Hello,

from this excerpt:

ERROR: [{"ret_code":-4611686018407202610,"message":"Not enough free space available for volume 0 of resource 'snap_pm-6ae4d75b_vzdump'.","details":"Resource: snap_pm-6ae4d75b_vzdump","error_report_ids":["6712BBF1-00000-000005"]

Can you verify if you have enough space in the storage pool(s)?

I have 300gb free but I still can't do the backup, but with a VM that weighs 330gb I can do it. Maybe it's because for an lxc container the same disk space that it occupies is needed free? Because the container contains 500gb although it only has 80gb used internally, and they are in Zfs
