Q: It said that there is no system partitions detected when you do system backup under Window.

Please check if the system partitions are recognized as blank status on AOMEI Backupper.If yes, it might be that some other applications prevent the system drive from being read by AOMEI Backupper, such as: RollBack Rx, Reboot Restore Rx, Drive Cloner Rx.

Q: Why does running an existing backup task report error 4123?

A: 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.

Q: Why does the backup fail with error 4101?


1) Please first check if ABCore.exe is prevented by your antivirus software. You can run ABcore.exe (under the installation directory of AOMEI Backupper) as an administrator to check if it can run successfully. Or, antivirus software(such as windows defender) will prompt that the program is prevented (please allow it).

2) The backup process needs "System" permission. Please check if your destination path has "System" permission. If not, please add "System" permission for your destination path and retry. You can add permission under "Propreties"-"Security" tab.

3) And, please check if the external drive is disconnected or its' drive letter is changed when you back up to an external drive. Please reconnect the external drive with the same drive letter as the target path.

4) If you back up to NAS, you can try to map the network drive as a local drive in windows and then please set the mapped drive as the destination location. 

Or, the NAS is disconnected because the unstable network or user account is changed when you back up to NAS. Please delete the NAS.xml file under C:\ProgramData\AomeiBR, and then reconnect the NAS via typing into IP address.
