olivierlambert said in Error restore backup:

No I mean the file level restore feature from XO. If it all worked, I'm curious to understand why you had this issue in the first place. Did you restore the entire chain?

We had to restore the entire VM as a new instance from Xen Orchestra using the delta backup. However, the same error occurred with each restore point. So, we manually copied the backup files from XOA and imported them.

Hi,
Unfortunately, it's not possible to provide the files, as they are managed underneath by FreeNAS and ZFS. However, the manual restoration worked successfully by importing the VDI files from the backup

olivierlambert The issue persists, and we encounter the same error when launching Xen Orchestra in the premium trial version. However, when we manually open the VHD file from the backup, it appears to be consistent. We are using Delta Backup. Is there a way to manually restore this VHD file? The backup was performed on XCP version 8.0.0, and we are trying to restore it on version 8.3. Could this version difference be causing the problem?

Hi, I have got issue when I want to restore backup from one VM.

Is stucks at about 60 percentage of 1 disk with error:

Expected values to be strictly equal: 0 !== 2097664

We have version 78ae1

We have XCP NG 8.3.0.
