[CLOSED] Unable to backup Debian VM

[vendo232]

I can backup to the same location other VMs just one is causing an issue ( the most important )

Getting following erros when I try to backup in 'STOP" mode

INFO: include disk 'scsi0' 'local-lvm:vm-100-disk-0' 164G
ERROR: Backup of VM 100 failed - unable to open '/mnt/pve/Plex/dump/vzdump-qemu-100-2024_04_21-13_51_42.tmp/qemu-server.conf' at /usr/share/perl5/PVE/VZDump/QemuServer.pm line 223.

Hi,
please share your storage configuration cat /etc/pve/storage.cfg and the output of pveversion -v. Is there anything specific about this VM compared to the others?

thank you for your reply. I went through the bottom yesterday. Decided to to migrate from 7to8 to see if it fixes my issue and it went sounth.
I had something blocking the upgrade from my CPU passthrough attempt and I could not figure out what to do with it.

Luckily i was able to backup magicaly the VM while I was upgrading!!! I know, gambling!

after couple of hours reimaged to fresh 8.2 , restored backup and running clean install today.

Storage management on Proxmox is something I need to learn more.
