6.4 backup issue

[Eneko Lacunza]

Hi all,

3 days ago we updated a PVE 6.0 host to 6.4 . It has been working 
without issue for more than a year since last update until then.

After the update, one of the VMs has issues with backups:


INFO: Starting Backup of VM 105 (qemu)
INFO: Backup started at 2022-01-21 00:05:35

timeout
INFO: Failed at 2022-01-21 00:06:00

Other VMs' backups work without issues. Scheduled backup for this VM has 
failed 3 times. Launching backup by hand fails sometimes, but after one 
or two retries, it works.

Any idea? :-)

Storage is default "local", filesystem-based.
Backup is being done for al VMs to local NFS server.
