1. Files backup copy have been blocked or damaged. To fix the error, you will initially need to restart your PC, which will solve the problem if files are temporarily blocked. If the reboot does not bring results, you will have to repeat the following algorithm:

• Delete the existing backup in the iTunes program settings (Settings -> Device tab) or move it to another folder.
• After that, connect your iPhone to iTunes again to create a new backup.
• If the above manipulations did not help, then you will need to create a new user who will have administrator rights. Subsequently, backups must be made on his behalf.

2. It happens that the iPhone does not create a backup copy due to outdated iTunes, Mac or iOS software. To fix the error, just download latest version and install the necessary updates.

3. Impossibility Reserve copy may be due to different time zones that are set on the PC and iPhone. Fixing the problem is quite simple - just check the box next to the line “Automatic change to daylight saving time”.

4. When backing up using iCloud, an error may occur if the account password cannot be verified, for example, after the user resets the password. To solve the problem, just log into your account again.

You've just had a long day and the last thing you need is for something as important as an iCloud backup to stop working. Unfortunately, this is an area where iOS 11 does a really good job of addressing its issues.

Of the many backup-related errors, you might get the message "Some files were unavailable during the last backup" is probably the worst, especially since you have no idea what exactly was wrong to begin with.

This usually happens for a number of reasons, ranging from poor network connections, backup management failures, and conflicting files. And that means working on a number of fixes that should hopefully resolve this issue.

So, without wasting any more time, let's get down to business.

Check connection

iOS 11 backups required Wi-Fi connection, and reliable - ideally you should have a full Wi-Fi meter. There is a known issue where iOS software updates won't download simply because the Wi-Fi connection counter is half full, so don't expect backups to be protected from anything like this. So consider moving closer to your Wi-Fi router and establishing a good connection.

That said, also consider unplugging and retrying. Wi-Fi connections. Often your connection may just freeze for no reason, and doing this will do wonders in fixing the situation. Just swipe up from the bottom of the screen and double-tap the Wi-Fi icon to make it happen.

You can resolve connection issues by resetting your network settings. Please note that you need to manually re-add Wi-Fi networks, and reconfigure any other changed network settings after the reset. Find and open Reset Network Settings using Siri Spotlight Search, then tap Reset Network Settings to perform full reset networks.

Try starting a backup. Was it completed successfully? If not, move on.

Reboot your device

iOS 11 isn't completely immune to common technical glitches, and there's nothing like a full restart to clear things up.

To restart your iPhone or iPad, press and hold the power button until the "Slide to Power Off" prompt appears. After your device turns off, press and hold the Power button again to turn it on again.

The iPhone X uses a slightly different shutdown procedure, which requires you to quickly press and release the volume up and down buttons. Once you do this, immediately press the Power button to bring up the "slide to power off" prompt.

If restarting the device did not allow the backup process to complete normally, continue.

Enable/Disable iCloud Backup

Since restarting the iOS device did not solve the problem, it may simply be a problem with iCloud Backup being faulty. The fix involves turning iCloud Backup on and off, after which the backup should run fine.

Step 1.

Step 2: Scroll down and tap iCloud Backup.

Step 3: Click the switch next to iCloud Backup to turn it off. In the pop-up window, click "OK" to confirm your actions.

Step 4. Wait ten seconds, and then tap the switch next to iCloud Backup to turn it back on. Click OK again on the confirmation pop-up window.

Step 5: Click "Backup Now" to perform a new backup.

Hopefully you should now see that the entire backup completed successfully. If you are still getting the error message “Some files were not available during the last backup,” let's move on to the next fix.

Sign out and return to iCloud

The latest fix focused on iCloud Backup glitches and how turning the option on and off might fix the problem. Since that didn't work, let's take it one step further and log out completely and go back to iCloud. Hopefully this will fix any remaining glitches and other anomalies associated with iCloud Backup.

If signing out of your iPhone or iPad deletes a certain amount of data, such as contacts associated with your account, you don't need to worry because all the deleted items are synced when you sign in again.

Step 1. On the Settings screen, tap your profile name and then tap Sign Out.

Step 2. Insert your Apple ID password when prompted to turn off Find My iPhone/iPad.

Step 3: Click "Sign Out" in both pop-ups. Wait a while for locally cached account data to be removed from your iPad.

Step 4. Return to iCloud using the Sign in to your iPhone/iPad option in the Settings screen.

Step 5: Click "Merge" in the prompts that appear to complete your iCloud sign-in.

After logging in, try running the update. If you still can't complete it successfully, it's time to get a little serious.

Delete previous backups

There are numerous complaints popping up on forums that previous backup files actually conflict with iOS when trying to create new backups, hence the infamous "Some files were not available during the last backup" error. If this is the case, then deleting the old backup should fix the situation.

Step 1. On the Settings screen, tap your name and then tap iCloud.

Step 2. In the Storage section, click Manage Storage.

Step 3. On the iCloud Storage screen, tap Backups.

Step 4. Under Backups, tap your iOS device.

Step 5. Scroll down and then click "Delete Backup". Click "Uninstall" in the "Turn Off and Uninstall" pop-up window. iOS should now remove any existing file iCloud backup.

Step 6. Deleting a backup also causes automatic shutdown iCloud Backup. Go to the iCloud Backup screen and then tap the switch next to iCloud Backup to turn it back on.

Now tap the Back up now option to start and complete a new backup. This time, your backup has a huge chance of completing successfully.

A couple of days ago I tried to do it in iCloud, but, unfortunately, without success: in the window located at “Settings” - iCloud - “Backup”, I was greeted with a message telling me what to create device backup impossible. Why did it happen? The answer to this question was left behind the scenes, but not the solution from idownloadblog.

If you also encounter a similar error, first of all, delete the old backup copy of your gadget from the cloud storage. You can do this on your iPhone or iPad in the “Settings” - - “Storage” section. Click Manage, select the backup, and delete it.

It happens that for unknown reasons it is not possible to delete a copy from the device. In this case, a computer comes to the rescue: on OS X, open “Settings” - iCloud (this is the iCloud control panel). Click “Manage” again and in the list of backups that opens, delete the unnecessary one.

Did not help? Then try logging out of your iPhone or iPad and then logging in again. Resetting your network settings in the General section of your phone settings may also help.

By the way, it is quite possible that the copy is not created due to the poor quality of the Internet connection. Connect to another Wi-Fi network and start the copying process again.

Problems when creating a backup copy in iCloud - solutions

Find all posts by sashalav. Find all posts by sashken. Find all posts by kharsanov. Find all posts by alyska. Find all posts by pallado.

To protect yourself from losing information if your Apple device breaks down, it is recommended to create a backup copy. But sometimes the operation fails and the copying fails. To correct an error, you must first identify the causes of its occurrence.

Why couldn't I create a backup via iTunes or iCloud?

Errors “Unable to create a backup copy”, “Error in creating a backup copy”, “Failed to create a backup copy” appear for the following reasons:

• iTunes version is outdated;
• The USB cable is not working properly;
• Internet connection and speed are unstable;
• too many backups have been created;
• the problem is in the device itself.

How to fix an error in creating a backup copy

If you do not know the exact cause of the failure, then follow all the steps one by one until you solve the problem.

Reboot the system

Try rebooting the device you are using. This action will restart all processes running in background, and will probably solve the issue.

Checking your Internet connection

The problem may be with your internet connection, so try connecting to a different one. Wi-Fi hotspot, reboot the router or check the mobile network status.

Application update

If you use iTunes, make sure you have the latest version of the program installed:

Updating iOS and programs

Make sure that the applications installed on your phone or tablet are updated and the firmware version matches the latest iOS version:

Freeing up disk space

Your computer's hard disk probably runs out of space, so you can't save a backup copy. Then open File Explorer and clear the memory.

Sign in to your Apple ID account

Sign out of your Apple ID account and sign in again. On iPhone, iPad, iPod touch this is possible through the settings:

On Mac OS and Windows using iTunes, just click on the account name, then on the “Sign Out” button, and then log in to the program again.

When you don’t have a computer at hand, but you really need a backup copy.

Mobile operating system ecosystem iOS systems designed in such a way that as soon as you connect your smartphone to charger, I have it at hand available network Wi-Fi, and iPhone screen or the iPad is locked, it starts copying photos, text messages, applications, mail, calendars and other data to the remote iCloud cloud. What to copy and what not is decided by the user in the corresponding menu: Settings - iCloud.

This is done for security purposes and the possibility of further data recovery in case of loss or breakdown of the device. If at least one of the three conditions is not met (the smartphone is not charging, there is no connection to Wi-Fi, or the screen is unlocked), copying to iCloud does not occur. Now imagine a situation where you are forced to go to another city for several days or weeks. You make new acquaintances, take a number of photographs, fill up your contact book with the numbers of interesting people... In a word, if you don’t have a computer at hand, a smartphone completely replaces it. But we rarely find time to create a full backup using the stationary iTunes application, and losing or breaking a device can turn into a real headache.

Anticipating human laziness, the developers included the ability to create backups without the need to connect to a Mac or PC. It's more convenient, it's faster and it will save you from digital losses. In addition, when purchasing a new smartphone “far from the homeland,” such mobile copying will allow you to easily start using the new smartphone with a complete transfer of all data.

What is saved in iCloud backup from iPhone

The algorithm for backing up directly from a smartphone is similar to traditional creation of copies using iTunes. A backup created exclusively using a smartphone will contain:

• application data;
• history of SMS, MMS and iMessage messages;
• device settings;
• Health data;
• purchase history: applications, books, music, movies;
• photos and videos (if iCloud Photo Library is enabled: Settings – iCloud – iCloud Photo Library – Enable);
• ringtones;
• HomeKit data and configuration.

Please note that music and videos not purchased from official iTunes stores and App Store, a backup created without using a Mac or PC will not be included.

Creating a Backup

To start synchronizing you will need a stable Wi-Fi signal. You can use either your home wireless network or use the Internet at the nearest restaurant, hotel or airport.

Open Settings - iCloud and go to Backup copy and turn the slider on.

Agree to the request to start the backup. Enter the password for the account you use in iCloud. After enabling backup, iPhone will display the current version of the last save:

Now you can start creating a new copy by clicking Create Backup.

The smartphone will warn you about how long ago backups were not created. In my case, two weeks have passed since the last save, and considering that I use the smartphone’s capabilities to the fullest, the losses could be great. The backup time depends on the quantity installed applications, downloaded music, videos and general “load” of iOS device. During copying, you can minimize the corresponding menu and use your smartphone: the process will take place in the background.

Restoring from a backup

To completely reset your iOS device for further restoration from the backup you just created, transfer to Settings – General – Reset – Erase content and settings.

Enter set password and select Erase iPhone. Enter your iCloud account password. The smartphone will reboot. All data will be deleted.

Regardless of whether you are setting up a newly purchased smartphone, or want to return the current settings to your native device, the further steps will be completely identical.

1. Once connected to a Wi-Fi network, select Recover from iCloud copy(Restore from iCloud Backup).
2. Enter the login and password for the account in which the backup was created.

3. Select the current backup and wait for the process to complete.

After restoring the settings (takes a few minutes), the iOS device will reboot. You will be required to re-enter your iCloud password and standard setting iMessage, TouchID service. When the Springboard appears, you'll be greeted with a familiar selection of apps and games that will immediately begin loading (connecting to a charger is recommended at this point in the recovery process).

Website When you don’t have a computer at hand, but you really need a backup copy. The ecosystem of the iOS mobile operating system is designed in such a way that as soon as you connect your smartphone to a charger, there is an available Wi-Fi network at hand, and the iPhone or iPad screen is locked, copying photos, text messages, applications, mail, calendars and other data begins to remote cloud iCloud. What...

If you haven’t found the answer to your question or something didn’t work out for you, and there is no suitable solution in the comments below, ask a question through ours. It's fast, simple, convenient and doesn't require registration. You will find answers to your and other questions in the section.

A couple of days ago I tried to do it in iCloud, but, unfortunately, without success: in the window located at “Settings” - iCloud - “Backup”, I was greeted with a message that it was impossible to create a backup of the device. Why did it happen? The answer to this question was left behind the scenes, but not the solution from idownloadblog.

If you also encounter a similar error, first of all, delete the old backup copy of your gadget from the cloud storage. You can do this on your iPhone or iPad in the “Settings” - - “Storage” section. Click Manage, select the backup, and delete it.

It happens that for unknown reasons it is not possible to delete a copy from the device. In this case, a computer comes to the rescue: on OS X, open “Settings” - iCloud (this is the iCloud control panel). Click “Manage” again and in the list of backups that opens, delete the unnecessary one.

Did not help? Then try logging out of your iPhone or iPad and then logging in again. Resetting your network settings in the General section of your phone settings may also help.

By the way, it is quite possible that the copy is not created due to the poor quality of the Internet connection. Connect to another Wi-Fi network and start the copying process again.

Problems when creating a backup copy in iCloud - solutions

Find all posts by sashalav. Find all posts by sashken. Find all posts by kharsanov. Find all posts by alyska. Find all posts by pallado.

The backup is saved to the location you choose in the same format as backups created using iTunes. For me, the message “iTunes could not create a backup of the iPad...” appears not in iTunes, but on the iPad. What should you do if an error like this occurs: “iTunes was unable to back up your iPhone.” And what to do about it, deleting the backup did not help.

If all the methods described above did not help you avoid some mistakes when creating a backup copy, then you can do this using this Apple service.

True, my message was “iTunes was unable to create a backup copy of the iPad...” and the reason seemed to be different, but it doesn’t matter. There is a problem with creating a backup copy and it needs to be solved somehow.

At least if some process in operating system is blocking backup files, then rebooting may solve this problem. Also, beginners will find the information given in the article useful: iPad backup, which explains why it is needed at all and how to completely disable it, etc. The backup takes a long time, and after some time the connection with the iPad may disappear for a moment.

Therefore, first of all, I advise you to save a copy on another drive, and the second point is to create a fresh account with administrator rights, which you can use to transfer it. Thanks for the instructions, there really is a problem, but the question is, how much of a backup is needed? Well, it doesn’t create it, so it doesn’t create it... Thanks for the answer, there is some awareness of the purchased product (iPad) and the importance of the backup copy. Thank you!

Created (in Windows 7) folders with the specified names and in the same sequence (missing ones). 1. In Settings -> The device tab in the window (name and time is assumed) is empty. No one ever... 2. I have windows 7. Users\[username]\AppData, etc. AppData being hidden now will be visible? This is just the beginning, what will happen next if I get to the backup copy. And another question, if I may be off topic, but this is because of the top five tomorrow.

1. The second screenshot in this article makes it clear that the name and time of the last copy have been recorded. I decided to create a new backup copy..... And I couldn’t, it says it failed. I deleted the old copy, but a new one is still not created. Computer 7 and HP laptop. On a laptop, backups are created without problems and quickly, but on a computer, the process simply “freezes” at the very beginning.

I tried to find backup copies using all the indicated methods, but they are nowhere to be found. I have Win XP. I don’t have many programs and everything else yet, but I would like everything to work fine.

Fixing the error “iTunes could not backup iPhone”

A multi-day struggle with “failed to create a backup copy” ended in victory, thanks to the reinstallation of Tuna and the removal of EVERYTHING that was manufactured by Appel, as recommended by sputnik1818.

The solution to changing the clocks helped. There was an error: iTunes could not restore the iPhone because the backup session failed. 33 GB, but it was not restored, it said that it was not possible to save the backup copy, but what if I found it through drive C. I clicked to create a new copy, the backup now weighed 27 GB, why?

Unable to Backup iPhone, iPad or Restore from iTunes Backup

COMPETENT in your questions. maybe I'll get lucky too. explain to the teapot - I got a window - iCloud copy, backups have not been created for 5 weeks. etc. Today we will tell you, dear readers, how to make a backup copy of your iPhone/iPad, what is included in the backup copy, where it is better to save a copy of your iPhone, and how to delete it. To protect personal data since the introduction of the iPhone in 2007, Apple has provided a simple but extremely important Backup tool.

A copy of the data is created on the iPhone/iPad and automatically downloaded to cloud service iCloud. In order to be able to create backup copies of data stored on an iOS device directly from the device, you need to enable “Copy to iCloud” in the device settings.

How to create a backup directly from iPhone?

On the Apple support website (support.apple.com) in the “Selecting an iOS backup location” section, developers give advice on how to speed up backup directly from your iOS device. This will allow you to get the backup file on your hard drive and have full access to it even when your PC is not connected to the Internet. Note: We recommend saving backups to an external HDD With large capacity or USB stick.

Alternatively, you can clear the main system disk so that iTunes can finish the backup. Perhaps many people face this problem, and an article about it will be useful. The problem is that this iTunes error can be caused by anything.

Can't Back Up Your iPhone, iPad, or iPod touch Using iTunes

Let's try to collect them all in this material. If this turns out to be useless, do a full reset (Settings-General-Reset-Delete content and settings). After this, you can take your iPhone to the service.

iTunes can't back up iPhone due to insufficient free space on computer

Surely, many iPhone/iPad/iPod owners have at least once encountered problems backing up their devices. Step-by-step instruction to overcome annoying errors when backing up iPhone/iPad/iPod in iTunes. Another frequently encountered problem when backing up a device is that the computer simply cannot recognize the device.

In “Settings”, select the required section and click the corresponding “Storage and copies” button. At this time, iTunes freezes a little. Further nuance: if you do not find this path in Windows Explorer or in Finder Mac Os, then the easiest way to solve the problem is file managers. In these programs you must enable the display hidden files. If the iPad freezes during this process and does not turn off (I had this happen too), then press the power button and Home button again and hold it.

It says that the backup session failed. Guys, help...))) Everyone doesn’t make a backup copy, but for me everything is worse... So, in order. Now you know where the backup is saved copy iPhone and how to find it faster than usual. Fortunately or unfortunately, an iPhone backup does not include all the information stored on the device or downloaded to it by the owner. If there is no backup in the device tab or it is not deleted, you can delete it manually from the operating system.

I encountered this problem a long time ago, but I never got around to figuring out how to cure this disease. The most interesting thing is that I have three devices for iOS: two iPads and an iPhone. There were no problems with iPads, but the iPhone refuses to create a backup copy from the moment of purchase. In general, today I figured it all out and am sharing it with you.

I am aware that Apple devices are not a mass product these days. This is primarily due to the exchange rate of the ruble and their prices. However, judging by search queries The topic of life hacks for treating minor software problems is very relevant. For example, “”, written in the summer of 2014, is still at the peak of popularity in search queries:

People go, read and say thank you. I am very pleased that my posts help solve problems.

Let's go back to the backup. As we know, backup in iOS is available in two ways: through the iTunes program and copying to cloud storage iCloud. I always use the latter. This is very convenient, because... no need to connect the device to the computer, press any buttons... all you need to do is put your phone on charge with wi-fi connected and go to bed. A copy will be created in the morning. It is also very convenient to restore your device when purchasing a new device. Just connect to your account and restore from the latest copy.

So, two ways to restore copying if it is not carried out automatically.

1. You need to go to Settings-iCloud, go down the menu and log out of your account. When you exit, the system will ask whether to leave the content, we answer - yes:

If a copy is still not created, then you can try the second method. You need to delete the previously created copy of this device. It is best to do this not from the device, but from the computer. I have a Mac, so the screenshots will be from Mac OS. On Windows, you need to go to the iCloud application and find a similar function.

2. On the Mac, go to Settings - iCloud

At the bottom of the window, click the “Manage” button:

In storage management, select “Backups” on the left and the copy of the device that needs to be deleted. As I already said, copies have never been created on my iPhone, for this reason there is simply no previous copy. If you previously created copies and suddenly stopped, then the last copy will be here. It needs to be removed:

After deleting, go to the device menu Settings-iCloud-Backups and click “Create a backup copy”

That's all! I hope you find this useful.

The gadgets of the American corporation Apple are rightfully considered the most reliable in the world. Despite this, even they can sometimes fail. So that the joy of buying a smartphone is not overshadowed by the sudden loss of a huge amount of information, you should first take care of its additional preservation. Among existing methods It’s more convenient and reliable to use special cloud applications. Particularly convenient is that cloud copies will ensure complete recovery of saved data at any time convenient for you, regardless of what model of iPhone or other Mac device you use.

Backup failure - description of the essence of the problem for Apple mobile devices

First of all, let's find out:

• What is backup?
• What does backup failure mean on iPhone?
• Why does the crash occur?

If you have lost, damaged, accidentally broken yours, or want to have access to information through other Mac devices, then additionally saving data from your iOS device to external media (backup) will save a lot of time, nerves and money. For this purpose, Apple has created an Internet service (cloud storage) for data - iCloud (we read - ICloud). The iTunes branded media player is perfect for storing and playing movies or music.

If the process of saving information does not proceed correctly or for some reason is not carried out at all, the system notifies about this by displaying “− backup failure.” It is logical that after this a trivial question arises: how to remove the iCloud backup failure? Let's take a closer look.

Causes and solutions to the error

If an iCloud backup failure still overtakes you, don’t panic and immediately run to the service center. apple center. It is quite possible to deal with this problem on your own, without resorting to the help of a “guru”. Depending on the source of the error, select the appropriate one or convenient way to eliminate it:

Problems with Apple servers

The problem with servers is two-way, since the connection between “smartphone” and “server” is assumed. How can we find out which of them prevents us from sleeping peacefully? It turns out that it is quite possible to check the status of the servers yourself in a short time, without nervously calling friends, frantically searching for news on the Internet and other dubious options. To check, use the System Status tool. Information is provided in real time. As you understand, we can’t fix Apple’s problem in any way, so we just have to wait until the servers are repaired and try saving again.

If everything is fine with the servers (and most likely it is), you need to look for the problem directly in the smartphone. First of all, difficulties may arise with identifying the device directly on the server. These include an error connecting to the Apple ID server.

Server problems often occur after updating an iPhone. First, you should check the identifier for functionality. This is easy to do: go to the company’s official website and enter your account information. What to do if it doesn't open? − You can create a new one. If, fortunately, everything is fine with your account, then the reason for the failure is related to other problems.

Network problems

The Internet is the link between the smartphone and the clouds. It is logical that the absence of a network makes it impossible to transmit information, resulting in a failure.

The simplest way to make sure everything is ok with the network:

• Connect other devices to the network;
• Connect the iPhone itself to another network.

If other devices connected to the Internet work, or the smartphone works when connected to another network, then most likely the culprit of the misfortune has been found.

The speed of operation should also be taken into account. Excessive fluctuations may cause failure.

System problems

The most common problem, the following methods are used to solve it:

The simplest way to treat many hanging diseases is to restart all processes that were running in the background. Suitable for eliminating the specified error and helps in about a third of cases.

To reboot, you must simultaneously press and hold the buttons for 5-7 seconds:

• Home and side button (for iPhone 6, iPhone 7 and later models, and iPhone X);
• Home and top button (for iPhone SE and earlier models).

After this, the company logo should appear on the screen. Then repeat the procedure for creating a backup copy in the chain: “Settings” - “iCloud” - “Backup”.

1. Deleting old backup versions

If previous method didn't give any results, it's worth trying to delete old backups. You can do this:

• Through a smartphone along the chain: “Settings” - “iCloud” - “Storage and copies” - “Manage”. Clicking the last button deletes the old backup
• Via a computer using the iCloud utility for Windows OS X, using the “Storage Management” section.

After completing the procedure, you need to disconnect the smartphone from the computer, then reset the network settings using the chain: “Settings” - “General” - “Reset” and try again to create a cloud backup.

By the way, too many backups can also cause a failure.

1. iOS software update

A fairly common cause of errors. To fix it, you need to check for software updates. The check is carried out along the chain: “Settings” - “Basic” - “Software update”. If the system offers updates, install new versions.

1. Buying additional space

If the failure is due to the fact that there is not enough free space in iCloud, the problem can be solved by purchasing additional gigabytes. The thing is that Apple provides free data storage only up to 5 GB. If the volume of your backups exceeds the free limit, you can simply purchase the missing gigabytes. To do this, you need to perform the following sequence of actions: go to “Settings” and then go to “ Account" After that, select “iCloud” and “Storage”. In the “Buy another seat” option, select the appropriate tariff and pay. It should be remembered that this fee is a subscription fee, not a one-time fee, and if the payment is delayed, some functions may not be available.

1. Freeing up space

If the amount of free space has been exhausted, and you don’t want to pay for additional gigabytes (for various reasons), you can solve the problem by removing excess, unnecessary, irrelevant, outdated, and junk information from the storage.

If there is nothing special to delete or it’s a pity, try optimizing the space. In this case, enabling several functions will help that force photos and videos to be sent to the storage, thereby significantly reducing its space. You can use the function as follows: follow the “Settings” - “Photos” chain, enable the “iCloud Photo Library” functions , “Optimizing storage on iPhone” and “Uploading to My Photo Stream”. Result: the “heaviness” is relieved, but not lost, and the phone’s memory is freed up for further comfortable work.

1. Disabling the option

If you're tired of constantly clearing media garbage into your storage, simply go to settings and turn off this option on your iPhone. This is not about disabling automatic copying of information “to the cloud”, but about preventing the smartphone from dragging everything there. For example, bad photos you take that are completely unnecessary automatically fly away and litter the cloud space, making it impossible to save truly valuable information. What to do in this situation? − Everything is the same as in the previous paragraph, only for the purpose of disconnecting.

1. Setting up folder synchronization

Folder synchronization helps iOS and iCloud agree with each other, and also provides access to other Mac devices. The easiest way to do this automatically is using the iCloud Drive utility. It is installed and launched one-time, creating a folder of the same name directly in the user’s folder. To synchronize, just move the files to the iCloud Drive folder and they will automatically go to the storage.

1. Contact Apple Support

If none of the proposed methods help resolve the problem, you will have to contact the Support Service specialists who will provide qualified assistance.

Data backup and recovery technologies have become more efficient over the past few years, but most administrators use them only as a last resort. Only if all other methods have failed do we try to restore the data from the backup. But to do this, you need to have confidence that the necessary data will be available at the decisive moment. However, Exchange administrators allow several typical mistakes that prevent backup and restore operations from running successfully.

Incorrect choice of archiving method

The two main methods for backing up Exchange data are online and offline. IN operational mode software interface Microsoft (such as the Extensible Storage Engine - ESE, custom APIs, or the Microsoft Volume Shadow Copy Service - VSS) provides copying of selected Exchange data while Exchange services are running and the target database is mounted and active. The APIs provided by Exchange archive and optionally truncate transaction logs.

In offline mode, the Exchange database and log files are copied until the database is mounted. Some solution providers claim that Exchange data is copied without using the Microsoft API or dismounting the databases. The article "XADM: Hot Split Snapshot Backups of Exchange" (http://support.microsoft.com/?kbid=311898) explains that Microsoft classifies such backups as offline backups.

For typical production purposes, hot copies are preferred because they provide a complete copy of the Exchange databases without interrupting user access. However, in some cases, offline backup is useful. For example, it is recommended that you take a full offline backup of your Exchange database and logs before you install Windows or an Exchange service pack, or before you move the database to another server. Creating offline copies is more time-consuming than online archiving, but many administrators choose to supplement regular working copies with periodic offline backups to improve security.

Saving unverified backups

A failure in the backup process may go unnoticed, but users will likely raise alarm if the administrator is unable to restore the data Email. I know of one company where the administrator accidentally corrupted the mailbox database. When trying to restore it, the administrator discovered that more than four months of backups were corrupted because installed version The third-party backup agent was not compatible with Exchange. The agent attempted to back up the files but was unable to because the Exchange Information Store (IS) files were open. Even a quick glance at the backup program's reports or the application's event log would reveal problems in copying Exchange data. Unfortunately, no one controlled the backup process. To avoid such a mishap, you should regularly check your backup program logs. You need to make sure that:

• the program copies the necessary data; check the correctness of the copy type, time and content;
• The backup process is completed, the requested data has been copied; look for possible errors;
• the copied data is suitable for recovery; if a tape is used, it must be read in another tape drive.

Make sure that the data can be recovered on the server and that Exchange can retrieve the information.

If one of the three checks fails, the cause of the failure must be found and corrected. For example, during a hot copy, Exchange calculates a checksum for each page and compares it to the checksum of the page on disk. If the checksums do not match, error 1018 is issued and the copying process stops. If errors are detected during the scan, the administrator will have a chance to correct the problems before stopping the copying procedure.

Even good backups may become unusable over time due to changes in the environment, backup software, Windows or Exchange configuration. The most reliable guarantee of success is regular checks, and the fastest and easiest way to ensure that your backups are working is to check the event log, applications and reports generated by the backup program. The event log should not contain any errors generated by Exchange during the backup period. The backup program report contains information about missing files and other errors.

Incorrect transaction log processing

The ability to recover an Exchange database is determined by the state of the transaction logs. If there is a valid set of log files for the database, then it is possible to recover the database from the point of failure. Conversely, if logs are lost or corrupted, the likelihood of full recovery is reduced. During the recovery process, Exchange attempts to replay log files sequentially, starting with the first log needed by the database (also called the low anchor log) and ending with the last available log (high anchor log). If there is no log file between the bottom and top anchors, log playback stops. The restore procedure cannot resume until the missing log file is restored.

Online backups automatically include log files as part of the backup set. During normal operation, Exchange continues to create new log files as transactions occur. These log files remain on disk until a full or hot copy is performed, at which point the Exchange IS process truncates or deletes the files. You cannot delete log files yourself. In some cases, you may need to copy the log files to a separate directory for safekeeping. The Microsoft article "Offline Backup and Restoration Procedures for Exchange" (http://support.microsoft.com/?kbid=296788) recommends saving copies of transaction logs to a separate location before restoring data from an offline backup.

When restoring with NTBackup, logs are not replayed unless the Last restore set checkbox is selected (or a similar checkbox in another backup program). The database being restored cannot be mounted unless this option is selected or the Eseutil /r command is used to manually start log processing.

If there are no transaction logs or at least one log file is corrupted, you should use free analyzer Exchange Server Disaster Recovery Analyzer (ExDRA) Microsoft. This tool analyzes the dismounted database, reports presence and absence of log files and possible options eliminate detected problems. ExDRA is a valuable tool when the recovery process fails unexpectedly, but the administrator still needs to understand the intricacies of the disaster recovery process and consult with Microsoft Customer Service and Support (CSS) or other experts.

Lack of time to copy

The backup process takes time. Each server configuration has an indicator bandwidth, which reflects the amount of data that can be copied or restored in a given time period. A common mistake is to underestimate the time required for recovery. Taking too long to recover sometimes results in service level agreement (SLA) violations and often leads to user dissatisfaction.

Microsoft recommends measuring the time it takes to back up your data and allowing twice as much time for recovery. Why does it take twice as long to restore than to copy? Let's say we need to get a 60 GB copy of a database using a backup system with a write speed of 12 GB/hour. Five hours is an acceptable time for a backup. However, when preparing to restore data, remember that simply reading the data will take five hours. The recovery process also requires the following steps:

• Find the appropriate backup media (if you are using removable media such as tape) or find the appropriate disk volume (if you are using VSS or SAN-based backups).
• Transfer the backup data to the server from which you are restoring.
• Create a recovery server or Recovery Storage Group (RSG), if necessary.
• Read the data from the backup media and fix any errors or problems.
• Replay transaction logs.
• Move data from the recovery server or RSG to production mailboxes.
• Mount the database successfully.
• Fix any related problems.

Meeting the requirements of this list is a serious task; If problems occur at any point in the process, subsequent restore operations will fail. The more experienced the administrator, the smoother the process. He more accurately estimates recovery time and has the skills to troubleshoot common problems in a specific environment.

Forgotten little things

Discussions about Exchange backup issues often revolve around copying and restoring data; this leaves out many other objects and data elements that also need to be copied and restored. For example, if there is a catastrophic hardware failure, the hardware must be replaced and Windows and Exchange installed on the new server before Exchange database and transaction log backups can be used. By backing up your Exchange server state, it is easy to restore your server and Exchange data and greatly speed up the return to normal operation without wasting time searching for CDs, product serial numbers, etc. If your Exchange environment has antivirus programs, spam filters, X.509 Certificate Authorities (CAs), fax connectors, or other support services, you need to make copies and restore their configuration, along with important data (for example, private keys and filter lists) to restore these services to their original working state.

System state backup using NTBackup collects all system data on the local computer, including the registry, Active Directory (AD) Directory Information Tree (DIT) files on the domain controller (DC), Windows data Certificate Services, DHCP and DNS server databases and other required data. Most third-party backup utilities also have this feature, but you can get by without these tools; With NTBackup, you can schedule a copy of the system state to a file on disk, and then inject that file into each Exchange backup. This method guarantees a timely updated copy of the system state. Don't forget to update your disk periodically automatic recovery system (Automated System Recovery (ASR). With its help, it is often possible to fix damaged instances of Windows without completely reinstalling the operating system.

Neglect of practice

It is best to master the data recovery process before problems occur. You can perform recovery even if the enterprise has only one database and a single server. To do this, you need to obtain a copy of Microsoft Virtual PC 2004 or VMware Workstation, build a test server and practice data recovery. When working with Exchange Server 2003, you need to learn about RSGs and how to use them. You need to learn how to restore data from the original server to another server using a backup program. Installation CDs and serial numbers products must be kept in a safe place (not in text file on the server that needs to be restored). It is useful to regularly train, restoring elements that will need to be returned to working order in the event of a real accident; depending on the characteristics of the environment, these elements can be separate mailboxes, individual messages, databases, storage groups (SGs), or entire servers. The time spent training will pay off if a failure occurs.

We spend time, save money

Many companies spend a lot of money on disaster recovery and resiliency solutions, only to find out too late that simply purchasing cutting-edge hardware and software is not enough. By using free utility NTBackup and low-cost backup systems based on tape or disk drives you can build a complete disaster recovery solution. To do this, you need to become familiar with backup and recovery, avoid the common mistakes discussed in this article, practice backing up and restoring data in your environment, and constantly monitor the processes. And then, in the event of an accident, you will be able to successfully use your skills.
