Hi all,

Yesterday I configured a backup task in a recently updated PVE 8.3.5 .

Tonight's first run was mostly OK, but 5 of the 61 Windows VMs where 
rebooted + started for the backup.

VM disk storage is on ZFS mirror, NVMe disks.

Rebooted + Started VMs have each 1 snapshot, virtio disk and qemu agent.

There is a VM with virtio disk and qemu agent, but without snapshot. 
That VM was not rebooted + started.

Other VMs don't have snapshot nor qemu agent. Disk is ide.

Seems snapshot is related.

Is this the expected behaviour?

Thanks

Forgot to mention that backup mode is snapshot.

Thanks
