Onderwerp: [PVE-User] Radical difference in Backup times for one Vm's

Wondering if anyone can suggest a reason for this. I have 7 VM's being backed off a node, direct to a USB3 external disk via a Directory based Storage

6 of the VM's have backup times varying from 8 min to 52 min. The "dh -h" 
sizes of their disks vary from 16GB to 57GB.

The 7th vm has a du size of 97GB and takes 4 *hours* (240 min) to back up.

It seems rather more than it should take compared to the others - any thoughts?

All VM's are windows, qcow2 on shared NFS storage. Backups take place at night when nothing else is using the hosts or network.
