I am using "smart mode" for backup jobs. The standalone job went through with and without "smart mode".

Removing the tag from the VM in question and adding it again did not help. I have also deleted the snapshot linked to the backup job and retried, with no change in behavior.

The VM is shutdown and I only turn it on when I need to. During backup it is usually not running.

Thanks again.

@itservices Hi,
It seems the parent of the backup chain is not found (a delta backup links to another delta and another, until you have a full backup, it seems a backup on this chain is missing).
Can you restart a backup chain to have a full backup? You can do it by reducing the retention in your backup job.

Hi @pierrebrunet.

Thanks for the tip.

Didn't help, unfortunately. Same error message regarding VDI_IN_USE.

@itservices It may be a storage or a xo issue. You can try to restart xo-server and retry the backup. If it is solved, it was an issue with xo-server not freeing your vdi. If it still happens, it will be a storage issue

I have restarted XO as well as my NAS several times since Saturday.

Still no change.

The problem still persists with commit e376a.

After installation of updates to XenOrchestra I reboot the VM. Still no backup on this one VM possible.

For now I have created a separate backup job which seems to be working.

Commit 1ba82 did change something. It transferred the VDI but then fails with the VDI_IN_USE on that particular machine.

Problem still persists with commit e9b66.

Thanks for the support!

@itservices Hi,
We did not forget you, working on it!

I am giving a short "report", when there is new version out and I have tested it.

Nice weekend @y'all
