Backups to PBS just fine for Linux VMs, Windows based ones get stuck

[nighty2k7]

Hi,

when backuping up to a PBS I have no trouble backing up linux based VMs, but all my backups of windows VMs get stuck.

* "Backup job failed" info on proxmox node, on the pbs side I see the VM ID, and when looking at the snapshot I have a rotating icon on "size"
* I already tried deleting all backups on the pbs, so I have 2TB of free space
* The PBS is a Intel Nux 8th gen with a SSD as boot drive and a 2TB SATA HDD
* It seems to write for some time, then gets stuck
* I can write the backup to a mounted CIFS share just fine
* pve v7.4.4, pbs v2.4.2

Any ideas? Do you need further information to help me out here?

Okay, here is what I did to work around it:

* installed proxmox on the nuc

* backups to the virtualized pbs now working just fine

-> pbs running native on the nuc gave me trouble
