HA Crash while Backup and turn PROXMOX Machine OFF

I installed Samba backup and set it to do a full backup at 3am. The next day I noticed that my HA crashed. My HA runs on a VM in PROXMOX (with autoboot). The VM was suddenly powered off. I then started the VM manually and everything worked again. (no backup)

Then I started a backup manually and the system was switched off again? What can that be (HDD full?!) Do you have any ideas?

Thanks in advance

i actually have the same setup here but without Samab Backup. When i try to create a manual backup or a automatic one before updating HA the VM just stops. I already tried to capture more detailed logs with Promtail but it didn’t show anything after starting a backup to the point where the vm shuts off…


on my Setup it was a result of to low RAM.
