Hello,
Just a feedback. I am having trouble using CBT Backups with NBD.
Host Details:
XCP-NG Version : 8.3 latest (stable)
Xen Orchestra: latest:stable (From Source)
The first full backup always seems to work. The delta backup gives the error: 'HANDLE_INVALID'
the writer IncrementalXapiWriter has failed the step writer.checkBaseVdis() with error HANDLE_INVALID(VBD, OpaqueRef:xxxxx). It won't be used anymore in this job execution.
Start: 2026-08-09 14:01
End: 2026-08-09 14:01
Duration: a few seconds
Error: HANDLE_INVALID(VBD, OpaqueRef:xxxxxx)
This is a XenServer/XCP-ng error
