Hi,

By wanting to backup my virtual machine in a some cases I have "backup failed" in both versions of proxmox 2.2-24 and 3.1-21 :
and here is the error message:

[COLOR=#000000][FONT=tahoma]INFO: starting new backup job: vzdump 100 --remove 0 --mode snapshot --compress lzo --storage Disque_Backups --node vm1[/FONT][/COLOR]

[COLOR=#000000][FONT=tahoma]INFO: Backup job finished with errors[/FONT][/COLOR]
[COLOR=#000000][FONT=tahoma]TASK ERROR: job errors[/FONT][/COLOR]

What could be the cause of this error ?
I made several research but I have not found any on this error.
thank you for helping me

Best regards,

Seem the VM is locked, caused by prevously aborted backup? Unlock with:

# qm unlock 100
