Linux 5.4.106-1-pve #1 SMP PVE 5.4.106-1 (Fri, 19 Mar 2021 11:08:47 +0100)
pve-manager/6.3-6/2184247e

Over the last weeks I have noticed the following behaviour. When running a
scheduled or manual backup of my VMs there is a high change that the proxmox server itself will completly freeze. The only resolution would be to force a reboot of proxmox. The issue occurs both when using USB attached storage as backup target or even local storage.

Anything specific in regards to configuration,.. I can look at to resolve this issue?

**full backups logs can be found attached**

anything in the journal at the time the server froze? anything on the display? usually a complete hard freeze points to faulty hardware / driver
