Hi!

I have a problem with backup and starting a VM after a backup failure.

My log:

INFO: starting new backup job: vzdump 103 --mailnotification always --quiet 1 --mode stop --storage Ev_backup --compress gzip
INFO: Starting Backup of VM 103 (qemu)
INFO: status = running

ERROR: Backup of VM 103 failed - unable to connect to VM 103 qmp socket - No such file or directory

I have found the similar issue in this forum (https://forum.proxmox.com/threads/qm-start-id-returns-malformed-json-string.44541/) but I don't want to restart my node. Maybe there are other ways to fix this?

Thank you.
 
hi,

which version are you running? pveversion -v

also could you post the VM config as well? qm config VMID
