Hey together :)
I just connected my Proxmox Backup Server (version 2.2) to my PVE (pve-manager/7.2-3).
Backupping works just fine, but every time I try to restore single files I receive following error message:

proxmox-file-restore failed: Error: Starting VM failed. See output above for more information. (500)

Any idea what causes this error?
If any further information is needed, I will provide it of course.

BR :)
 
well, what is the output above mentioned in the error message? : )
 
So, no information at all that in the task log? Please also check the PBS logs.
Also take a look at the server status. Were the pbs out of ram when you did the restore?

within the PBS task-log I received this log:

RAM on the PBS looks Ok as well. It has 4GB RAM and there is not other Task running.

please check the logs in '/var/log/proxmox-backup/file-restore/qemu.log' on the pve node
 
Hey Dominik,

not saying much:

Code: 
root@pve92:~# cat /var/log/proxmox-backup/file-restore/qemu.log
[2022-06-01T08:56:46+02:00] PBS file restore VM log

BR,
Patrick
 
you could try to invoke the 'proxmox-file-restore' commands manually, this should give more output (hopefully)
 
Hey Dominik,

if you can tell me, what exactly to do, of cause... I'm struggling with the exact parameters... I can see the snapshots with the backup-client, but I'm not aware how I can do a restore from command line.

Code: 
root@pve92:~# proxmox-backup-client list --repository pve92@pbs@xxx:8007:pbs-backup1
Password for "pve92@pbs": ****************

check the 'proxmox-file-restore' command e.g. the manpage: 'man proxmox-file-restore'
there is a 'list' and 'extract' command

e.g.
Code: 
proxmox-file-restore list <snapshot> <path> --repository <repository>
i'd start with the path '/' and then work your way forward until you get an error (if you get one)
 
HI Dominik,

ah, okay:

Code: 
root@pve92:~# proxmox-file-restore list vm/187/2022-05-31T22:00:04Z / --repository pve92@pbs@xxx:8007:pbs-backup1

I still have this issue :(
Rebootet the host and the pbs. The host is inside a cluster - should the whole cluster be rebooted?

that should not be necessary as it does nothing for that issue..
can you post your pbs & pve versions?

EDIT: add '& pve'
EDIT2: after thinking, which host did you reboot? for the file restore, the host where you connect to is relevant, not where the target vm is

Thanks for your fast reply! :)
I rebooted the host containing the VMs. So the proxmox-infrastructure is setup as cluster. So I connected pbs at Datacenter/cluster level. Where can I find out which host pbs connects to?

Will send you the versions when I know which host to check :)

Thanks and BR!

with that i mean the host (hostname/ip) which you enter in your browser and you connect to.
