I think the import is showing progress for the vm (docker of things) because the the target storage is not qcow2 enabled (yet) its reconverting it on the fly. -[XO] Importing content into VDI [Importing] Docker of Things

Also vms will get this error sometimes.

Updated to XO to latest commit was 4 behind (88a89) and ran backups again.

Both full and delta passed...

Full - 2026-04-17T11_32_42.906Z - backup NG.txt
Delta - 2026-04-17T13_26_54.973Z - backup NG.txt

@pilow

I just restarted tool stack on both pool master and second host. Re-edit backup job to remove the purge snapshot with cbt and re-ran a delta backup. Which still fell back to full backup.

i'll create a new topic for this

in the time being, if you can, do a toolstack restart on your pool when no tasks is ongoing
your backups with NBD could be better (spoiler alert : iptables rules... 😃 )

Yes...

Think i have solved it / fixed it... I ran the errors though AI and it suggested running a full backup to reset the chain. Full backup was successfull with out issues. Running delta backup now as we speak but looks good so far.

One mistake i made is enabled the purge snapshot with CBT and now vms now failling to full backups.

we 'll check for the progress bar
