Element not found or the image file not found.
Solution: If you get the error message during the backup process, please reinstall the software and then rerun the backup.
Error code: 0x000020e6
Find no unused space to store temporary files.
Solution: This error occurs when you run a sector-by-sector backup of the disk and the computer only has this one disk. In this situation, AOMEI Cyber Backup will backup all sectors whether used or not, so there is no space to save temporary cache files, please change the backup mode to "Intelligent Mode", or you can connect another disk to the computer. Please change the backup mode to "Intelligent Mode" under Backup Options, or you can try to temporarily connect a USB drive so the program will save temporary cache files to another drive so that the backup will be finished successfully.
Error code: 0x000020e7
The source partition or volume can not be backed up sector by sector.
Solution: Generally, the error occurs when you use the sector-by-sector backup way to do system/partition/disk backup and you also select a backup source partition as the destination to save backup. Please select another location as the destination, or select "Intelligent Mode" under Backup Options. Note: when you back up Bitlocker encrypted partitions (uncrypted state) or no-NTFS/FAT32 partitions, AOMEI Cyber Backup will use the sector-by-sector backup way by default, even though you select "Intelligent Mode", in this case, please select another location as the destination to save backup.
Error code: 0x000020ea
Failed to get bitmap
Solution: Please reinstall the software and then recreate the backup to run. We suggest that you use sector-by-sector mode configured in the Backup Options. And, please use chkdsk /r command to check and fix the partitions you would like to back up before backing up them.
Error code: 0x000020eb
All partitions that need to be backed up have not been found.
Solution: When the source partitions have changed, for example, the starting sector, partition’s size, or/and some other physical configuration has been changed, the program can’t detect the same source with the record of the backup task, then you will get the error. Please try to recreate the backup task. Note: If all disks fail to be listed after you do an automatic update for AOMEI Cyber Backup and then cause the error, please try to reinstall AOMEI Cyber Backup manually.
Error code: 0x000020fc
The backup driver works improperly, you could restart the computer to solve the problem.
Solution: please check the following items on the client computer:

2) Please select Start-->Settings-->Update&Security-->Windows Security to open Windows Security Center (or search and open Windows Defender). Then select “Virus&threat protection”, and click "Manage Settings" under Virus&threat protection settings to add the install directory of AOMEI Cyber Backup to exclusion. And, continue to click "Manage Ransomware Protection" under Ransomware Protection, then click “Allow an app through Controlled folder access” to add ABCore.exe of the install directory of AOMEI Cyber Backup as allowed apps.
Or, if you run any other antivirus software on the client computer, please try to add ABService.exe, BCore.exe and Backupper.exe to the white list of the antivirus software.
3) Please type into “cmd” at Start Menu, run Command Prompt as administrator to open Command Prompt window, then run “net start ambakdrv” to check if the drivers can be started.
Error code: 0x00002139
Exceeds the maximum 2TB partition size of the MBR disk.

Error code: 0x0000215f
The operation has been canceled.
Solution: Please try to manually run the backup task and check if it will require an interaction operation. When you don't respond to the interaction operation during a schedule backup, it will cancel the backup.
Error code: 0x000021be
The file record is invalid in MFT, please try to use chkdsk.exe in command prompt to fix and retry.
Solution: If you get the error when you do a restore, it is caused by the source partition having some File System error. Generally, if the source partition you backed up still exists, you need to use chkdsk /r to check and fix the source partitions and then recreate the backup. But, if the source partition doesn't exist, sorry that the backup can't be restored further. Ps. If it is a disk backup, you can try to restore partitions one by one.
Error code: 0x00002335
Failed to create storage.
Solution: Please rerun the backup to check again. If you still get the same error, please contact the support team and offer the log folder of client computer (generally, it is C:\Program Files (x86)\AOMEI Cyber Backup Agent\VolBackupCore\log) to check further.
