Failed Backup of Nextcloud LXC

[nicedevil]

Hey guys,

I was running a backupjob for a couple months now for my whole environment, ofc successfull
Now I started a new node in my cluster and moved over my nextcloud LXC to it.
Nextcloud is working but the backup is failing one day after an other:

maybe you could help, and yes the container was running on ZFS in the past.

Hi have you tried mode stop?

Hi have you tried mode stop?

yep did this 2 hours before, this is working, but I want the minimum of suspend back :/

I also have this problem... Would also be glad for a real solution.

I also had the same error in the past.
Rsync error code 11 means no Space left.
AFAIK when making a lxc backup it's first put in a temp dir on the node (you can change the directory location in vzdump.conf)
https://pve.proxmox.com/pve-docs/vzdump.1.html (it's the tpmdir option)

Your /var/tmp is probably running out of space. The solution is to use a temp directory on a larger local storage/partition

Space is not the problem. I have a different problem than yours. I had 2TB and the lxc i was trying to backup only had 16GB root and 16GB mounted disk. I heard that this was a bug when I was did have this problem. Funny thing is that other lxc with bigger disks worked perfectly. Sinced then i only did mode stop on certain lxc. Haven't changed it since then since i do my backups at 2 am anyways.
