[SOLVED] PCT Container not Backing up to PBS or Local


Aug 15, 2021
Hi All,

Hope you're all well.

Struggling to get my head around this one. I have a PCT Instance running which just wont backup and gives an error as follows:

INFO: starting new backup job: vzdump 250 --remove 0 --mode snapshot --storage PBSneo --notes-template '{{guestname}}' --node EarthSpacedock
INFO: Starting Backup of VM 250 (lxc)

INFO: Failed at 2023-08-28 09:59:48
INFO: Backup job finished with errors

Any Ideas as i've exhausted many items such as adding the TMP Files to the whitelist for backups etc.

Would be grand.


Code 23 with rsync usually means that some files could not be transferred. Anything special about your CT? Can you share the configuration (pct config )? Does a backup work when the CT is shutdown or when using the stopped mode instead of the snapshot backup mode? Anything in journalctl around the time of the backup failure?
Hi Leesteken,

Thanks, please find the config:

features: fuse=1,keyctl=1,mknod=1,nesting=1
hostname: ReverseNEO
memory: 512
net0: name=eth0,bridge=vmbr0,firewall=1,gw=,hwaddr=36:62:34:27:EA:12,ip=,ip6=dhcp,type=veth
onboot: 1
ostype: ubuntu
protection: 1
rootfs: ESD-lvm:vm-250-disk-0,size=8G
swap: 512
unprivileged: 1

Other information will follow.


I basically recreated the whole PCT Setup and now works. Must have been an issue on how I was handling MariaDB in a Docker Instance.
