How to backup and restore a UEFI based system drive, backup dynamic volume or backup data to share/NAS network? AOMEI Backupper’s FAQ will answer these questions.

Does AOMEI Backupper support backing up and restoring MBR dynamic volumes?

For MBR dynamic volumes backup, you can use System Backup and Partition Backup, Disk Backup function is not supported yet. Note that you can only restore them to the original location or a basic disk.

Does AOMEI Backupper support clone volumes on a dynamic disk?

For volumes on dynamic disk, System Clone and Partition Clone are supported, Disk Clone is not supported yet.

Does AOMEI Backupper support backup/clone GPT dynamic volumes?

Currently, AOMEI Backupper does not support dynamic GPT disk backup and clone.

You get too large/small window of AOMEI Backupper.

If the window is too small and you are using a high resolution on your computer, please check “enable the large window mode” option under Menu-->Settings-->Other.

If the window is too large, please check “enable the large window mode” and then unmark it. But if the option can’t be marked, please find BackupRecovery.ini file under the path C:\ProgramData\AomeiBR\ and then cut it to other location. Finally, please rerun AOMEI Backupper.
BTW, the “Program Data” folder is a hidden folder, so you first need to show hidden files/folder in Folder Options.

The old backup files are not deleted with backup scheme.

Please check if the versions of backup have reached the number you set. And please note that these old backup files which are produced before enabling the backup scheme will not be deleted.
If you edit the backup task, backup scheme will recount the number of backup version based on the first backup file produced after you edit backup task. If all is ok and the backup files still are not deleted, please try to recreate the backup task and set the backup scheme.

AOMEI Backupper can’t find the system partitions or can’t see the disks under windows.

Please make sure the drive is listed under Windows Disk Management. 
Please check the type of this drive. Backupper doesn’t support eMMC storage device. 
Please check whether or not the drive is 4096 bytes per sector. You can install and run Partition Assistant, then right click a partition on the drive-->select Properties-->File System Info to check it. Backupper doesn’t support drives with 4096 bytes per sector.

When you restore the disk image from GPT disk with 5 (or more) partitions to a MBR disk, you get the message said that system refuse to restore more than 3 partitions because the destination drive not UEFI.

Because MBR disk only support 4 primary partitions, you can’t directly restore the GPT disk image with 5 (or more) partitions to MBR disk. So you need first convert the MBR disk to GPT with AOMEI Partition Assistant and then restore.

What does it mean about “User interaction required” in email notification?

When the schedule backup is performed, the program might need you to confirm some operations. At this time, the program will send an email to request the interaction. But, if you don't respond the "User interaction required" timely, the program will select a default option and then continue to do the operation.

Why send email notification test encounter “Sorry, failed to send text message” error?

For Gmail Sever: When you set up email notification with Gmail server, you may encounter this issue, as far as we know, it is because Google enhanced Gmail’s security level, you need to turn on access for less secure app in Google setting , then retry.

For Custom SMTP Server: AOMEI Backupper requires SMTP authentication, it does not support anonymous access. if you set up it without credentials, you will encounter this error.

Why Outlook OST files not being backed up with System/Disk Backup?

By default, AOMEI Backupper uses Volume Shadow Copy Service (VSS), in this way, Outlook OST files are excluded from being backed up.

To solve this problem:

    . Run regedit

    . Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToSnapshot

    . Delete the key value OutlookOST

    . Restart PC

Whether or not AOMEI Backupper can be installed to a path that contains semicolon?

No, installing to a path that contains semicolon will lead to AOMEI Backupper Service startup failure.

Why AOMEI Backupper encounters error “Failed to enable backup service. Please retry or reinstall the software…” when doing backup, how to solve it?

1 If you install AOMEI Backupper to a path contains semicolon (;), you will get the failure when running a backup task, please reinstall AOMEI Backupper into a path without semicolon.

2 Please check ABService.exe if it is running, you can open Windows Task Manager (press CTRL+SHIFT+ESC) -> Details (or Processes) and check status column if it shows running, if not, please go to Windows Services to manually enable it.

What else should I take note of when backing up using the Command Line with AOMEI Backupper?

There are four things to note:

1. You cannot back up data to disc (CD/DVD) by using command line. If you want to back up data to disc, please use the AOMEI Backupper GUI.

2. When you back up dynamic volume(s), but the dynamic volume has no drive letter, you should assign a drive letter for it first. You may then back it up by using command line later.

3. AOMEI Backupper command line program must be run by a user with Administrator privileges. If you are a non-Administrator user, a window will pop up, in which you need to enter the correct account information to finish the backup process.

4. When you back up data to shared network or NAS, you must provide a valid IP address, such as "\\192.168.0.10\foldername", in order to identify the network path.

What else should I take note of when backing up files/folders with AOMEI Backupper?

There are five things to note:

1. In order to avoid backing up temporary files, garbage files and other useless data, we suggest you perform a data clean up first and back up later.

2. Files and folders in the Recycle Bin cannot be backed up.

3. AOMEI Backupper can effectively back up files like NTFS compressed files or EFS encrypted files, but the files will no longer have NTFS properties after restoration.

4. AOMEI Backupper can back up NTFS files along with their security permissions automatically, and also supports restoring each file’s security permissions together with the file.

5. We suggest you first put the files you plan to back up into the same folder, and then back up this folder. To save all those files you would then only need to add one backup source to the Backup List, rather than several (Note: every item in the Backup list is called a backup source). This would make backup management more convenient. We suggest you do not add too many backup sources to the Backup list (e.g. the backup source count has reached 2000 or more).

Some files may be in use by other programs exclusively, and these may not be backed up. In that case, AOMEI Backupper will prompt you, and guide you step-by-step.

I have received the message: “If the program is unable to restart the computer or failed to enter into Restart Mode, you could…” How do I resolve this?

If some files or partitions are occupied by other programs, the restore operation will be performed under Restart Mode. However, AOMEI Backupper may fail to enter into Restart Mode automatically because of some unknown error such as a power failure while the task was being performed. You can make a bootable disc by clicking "Utilities" -> "Create Bootable Media" and boot from a CD/DVD to backup or restore.

Solution: Always make sure you have created a Windows PE bootable disc based on legacy boot mode (not UEFI boot mode) or make a Linux bootable disc manually. This will enable you to boot your computer from the bootable disc to restore data.

I received the message: “When failed to create a bootable USB drive or disc directly, you could…” How do I resolve this?

When creating a bootable disc using the “Burn To CD/DVD” or “USB Boot Device” option, some unknown errors may have occurred during the creation process , causing failure to make a bootable USB drive or bootable disc. You can solve this by an alternative solution: In the "Select Bootable Media" dialog box, choose "Export ISO File" instead of "Burn To CD/DVD" or "USB Boot Device", and then use third-party burning tools to burn the ISO file to USB, CD or DVD.

I received the message: “After completing the bootable disc, if it is unable to boot the computer, you could…” How do I resolve this?

After creating a bootable disc, it may rarely fail to boot because of some unknown error in the process of creating the bootable disc. You can solve this by another solution: Instead, make a Windows PE bootable disc based on legacy boot mode (not UEFI boot mode) or make a Linux bootable disc. In the "Select Bootable Media" dialog box, choose "Export ISO File" instead of "Burn To CD/DVD" or "USB Boot Device", and then use third-party burning tools to burn the ISO file to USB, CD or DVD.

Does AOMEI Backupper support backing up and restoring a UEFI based system drive?

Yes, it completely supports UEFI boot backup and restore, while ensuring your system bootable after restoration. Click here to learn more.

I have received the message: “Because the image file exists in a dynamic volume, you need to make a bootable CD based on Windows PE...” How do I resolve this?

If there are programs still running on the destination partition during the restore process, the program will automatically restart the computer and run AOMEI Backupper from the Linux Bootable CD or WinPE Bootable CD to complete the restore process. This problem arises because an image file in a dynamic partition cannot be recognized by Linux Bootable CD.

    · To solve the problem, either:

    · Copy this image file to a basic partition and then restore again, or

    · Click Utilities -> Create Bootable Media, to create a WinPE Bootable CD. A WinPE Bootable CD is able to recognize image files in a dynamic volume. Then run AOMEI Backupper on the desktop or use this CD to complete the restore process.

I received the message: “Because the image file exists in a share/NAS network, you need to make a bootable CD…” How to resolve?

If the image file is kept in a share folder or a NAS device, you will receive the above message if there are programs still running in the target partition which cannot close. 
To solve the problem, you only need to click Utilities -> Create Bootable Media to create a bootable CD. Then, use this CD to boot your computer to complete the restore process.

I received the message: “Because the system partition exists in a dynamic disk, you need to make a bootable CD…” How do I resolve this?

·  There are two methods available to deal with this problem:

·  Click Utilities -> Create Bootable Media to create a bootable CD based on Windows PE. (Not a Linux Bootable CD). Then open AOMEI Backupper on Windows desktop to try again.

·  Create a Linux Bootable CD or a Windows PE Bootable CD first. Then set this created CD to be the first bootable device in BIOS. In this way, AOMEI Backupper will run automatically when the computer is turned on. You can then click the Restore button in the main interface, then click “Path: Browse a path to select an image file and restore data from the file” to complete the restore process.

What should be paid attention to when you use AOMEI File Sync?

There are 4 aspects you should pay attention to:

    1. After synchronizing file, any changes on target files and folder such as delete, add or rename one of them, will cause that target files or folder are inconsistent with source ones. This situation will not benefit for file management.

    2. AOMEI File Sync supports VSS (Volume Shadow Copy Service), therefore, AOMEI Backupper can normally synchronize the files that are being used or occupied by other programs, but, you need to make sure that the "Volume Shadow Copy" service in your computer is enabled status.

    3. The main function of AOMEI File Sync is to help you to synchronize working files and user data files, however, if there are some special system files or files with special security attributes in source folders (e.g. C:\boot\bcd, C:\Windows\CSC), they are not synchronized.

How to back up or clone partitions and dynamic volumes that have no drive letter under command-line?

1. If your partition has no drive letter, you can use the index of partition on the disk to specify this partition. For example, partition D is on the second location of the first disk, then you can use “1:2” to replace drive letter D. You can find the index of disks and partitions by program’s inquiry command “/L”.

2. If your dynamic volumes have no drive letter, we can only suggest you assign your dynamic volumes drive letters first, then do backups.

What makes backup scheme become invalid?

1. Maybe it’s because you deleted the previous image files manually, and this results in the version chain of backup task being damaged so that the backup schemes become invalid.

2. Or maybe it’s because the program has something wrong which leaded to the invalidation of the backup scheme. Under this circumstance, you need to contact our support team to get help.

Why importing an image file can’t generate a task?

It may because the image file you imported has corresponding task in the task list of Home screen so there was no new task being generated after importing. In this case, you need to delete the corresponding task, then import again.

Click here to learn more about importing task.

Why task schedules weren’t actually executed as type you set after setting full backup, incremental backup, differential backup in “Advanced” of task schedule?

1. Maybe it’s because you only created scheduled task but didn’t do backup immediately. No matter what type of operation you have set, you should make a full backup at first, and operate as the backup type of your setting in the future.

2. It may because when you set scheduled task, you also set backup scheme at the same time. If so, the program will ignore the backup type you set in schedule, but take backup operation according to the setting of backup scheme.

The bootable ISO creation failed with message: “Can’t find some necessary files”.

Please check if there is the Winre.wim file under the path C:\Recovery\WindowsPE (it may also be in system reserved partition). If the file is in here, please modify the access permission of the recovery folder to "everyone" and then create again. Btw, the recovery folder is a hidden folder, so you first need to show hidden files/folder in Control Panel-->Folder Options.

AOMEI Backupper fails to install because it can’t replace the existing file (C:\Windows\System 32\ammntdrv.sys).

Please browse the path C:\Windows\system 32, then find and delete ammntdrv.sys file manually. After that, please reinstall the software. Or you can directly skip the message and continue to install it.

AOMEI Backupper can’t recognize the USB drive, USB mouse, keyboard or other devices in WinPE created by AOMEI Backupper.

The problem might be because there are not the corresponding drivers in the WinPE. You can recreate the WinPE and add these drivers manually. Click here to learn more details.

What does it mean about “User interaction required” in email notification?

When the schedule backup is performed, the program might need you to confirm some operations. At this time, the program will send an email to request the interaction. But, if you don't respond the "User interaction required" timely, the program will select a default option and then continue to do the operation.

When you connect your Network drive via AOMEI Backupper, you get the message: “Failed to access the network path, please...” or “A specified logon session does not exist......”

Please check if the computers or programs connected to NAS have reached the ceiling of NAS. If yes, you need to disconnect some computers or programs so that the AOMEI Backupper can connect the NAS to do the backup. If not, please delete the "NAS.xml" file under the path C:\ProgramData\AomeiBR. After that, please connect your NAS again.

When you edit /restore a backup, you get the message: “Unable to get the backup information because the image file does not exist, or it can’t be access......”

The problem might be that the task can’t locate the backup files due to unknown reason. You need to re-import the backup task by browsing the backup files. Click here to learn more details.

AOMEI Backupper can’t detect the internet under Windows or WinPE.

1. If you are using the virtual network that is connected to a proxy server under Windows, AOMEI Backupper can’t detect the internet.

2. If it is connected via wireless network, AOMEI Backupper can’t detect the internet under WinPE.

3. If you AOMEI Backupper can’t connect the internet in WinPE, maybe there is not network card driver. Please recreate the WinPE and add these drivers manually during creating.

Or, you can download PE build environment beginning with AOMEI Backupper version 4.0.5, the PE build environment is based on Windows 10 with lots of common drivers included, so you may not have to add drivers like network adapter or NVME/m.2 etc.

Why cannot you run backup task again when the target location of the backup task is CD/DVD?

AOMEI Backupper doesn’t support to run backup task again when the destination is CD/DVD.

Why can’t see the small tray of AOMEI Backupper when the scheduled backup is performed with standard account?

AOMEI Backupper needs to acquire the administrator’s permission to run the interface program, while only use system permission to run backup. The small tray is a part of the interface program. Under the standard account, AOMEI Backupper can’t get the administrator’s permission to run the interface program and so the scheduled backup will be performed without the small tray.

The shutdown event backup doesn’t run after you power off the computer?

The shutdown event backup is based on the shutdown of windows. You can click the “shut down” or “restart” button in Start Menu to enable the shutdown event. However, if you power off the computer, it directly cuts off the power to close the computer forcibly. In this situation, the program can’t get the windows shutdown information to perform backup.

The event backup doesn’t run after the event occurs.

1. Please check if AOMEI Backupper Schedule Service is enabled in Windows Services (you can run “services.msc” to open Windows Services). If not, you can enable it manually or reinstall the software. The AOMEI Backupper Schedule Service will enable backup program to run backup when the event occurs.

2.Please check if abnotify is running in Windows Task Manager. If not, please find the abnotify.exe under installation directory of AOMEI Backupper to run. However, if the backup task still can’t run, please reinstall the software and backup again. The abnotify will tell AOMEI Backupper Schedule Service to enable backup program when the event occurs.

3.If AOMEI Backupper Schedule Service and abnotify are run normally , but the event backup still can’t run, please attach the log files under installation directory of the software to contact us.

The event backup doesn’t run on this day after you check “Run one time every day” in event triggers.

If the backup task has been executed on this day, the event backup will not run again when the event occurs this day.

There is not image file after the shutdown event backup is executed.

1. There may be user interaction operation when the shutdown event backup is running. Because you can’t see and respond the interaction during shutdown, the program cancels the backup and then turn off automatically. So, the image file is not produced. We suggest that you can run the backup manually in windows to check the interaction operation and then re-edit the backup to cancel interaction request during shutdown.

2. If you don’t see the interaction request when you run the backup manually in windows, please make the backup run again during shutdown. If there still is not image file, please attach the log files under installation directory of the software to contact us.

The program needs to open an interaction window which is waiting to be interacted by user in the following situations when the program invokes the small tray to run the backup.

A: In the three situations, the interactive window is waiting for response three Minutes during backup/sync. If it does not get response, the program will choose a default one to process automatically.

1.The interactive window shows that you need to restart or skip the files when you backup/sync the files accessed by other programs.

2.The interactive window shows that you need to enter the NAS username and password when the program cannot connect the NAS.

3.The interactive window shows that you need to make more space available when there is not enough space to save backup in destination.

-----------------------------------------

B: In the four situations, the interactive window is waiting for response until you do it.

1. The interactive window shows that you need to insert a new CD/DVD after the last CD/DVD is used up when you back up to CD/DVD.

2. The interactive window shows that the CD/DVD will be erased after you insert the CD-RW/DVD-RW when you back up to CD/DVD.

3. The interactive window shows that you need to register when the backup starts to run if the software is not registered or the trail has expired.

4. The interactive window shows that you need to confirm the operation when the program needs to reboot into the WinPE to complete the backup.

Why need to register again when running the portable version of AOMEI Backupper Technician that has been registered already?

The possible reason is that other edition of AOMEI Backupper has been installed in the current system. Two different editions cannot coexist in a system.

Note: If your question can't be found above, please describe more details about it, then send email to us.
