Hello,

we have a PVE Cluster runnning in version 8.2.7. We try to make backups from our LXC containers but every time the backup hang and won't finish. I notice in the task log, that the backup job suspend the container for the snapshot, What surprises me, why make a susped for snapshot?

Bash:
INFO: starting new backup job: vzdump 1145 --notification-mode auto --storage PBS-TEST-LXC --remove 0 --notes-template '{{cluster}}, {{guestname}}, {{node}}, {{vmid}}'  --node prod-01 --mode snapshot
INFO: Starting Backup of VM 1145 (lxc)
INFO: Backup started at 2024-09-30 11:35:58
INFO: status = running
INFO: CT Name: ldpgs
INFO: including mount point rootfs ('/') in backup
INFO: including mount point mp1 ('/home/tdas') in backup
INFO: including mount point mp2 ('/mnt/ldpgs/refdata') in backup
INFO: backup mode: snapshot
INFO: ionice priority: 7
INFO: suspend vm to make snapshot
INFO: create storage snapshot 'vzdump'

we also have a slightly older PVE in Version 8.2.5 running and there the snapshot backup for a lxc is running nromaly and didn't suspend the container.

As storage a ZFS is used in both cases.
