can't create backup from LXC

[MisterY]

Hi,

I restored a LXC and I want to make a new backup. But now I get everytime this error:

any ideas?

if I set the Backup = 0 for the mp0-2, it works. but I want them to be backuped

how does the container config look like?

arch: amd64
cmode: console
cores: 8
hostname: Nextcloud
lock: backup
memory: 2560
mp0: ZFSTank:subvol-151-disk-1,mp=mnt/data,backup=1,size=500G
mp1: ZFSTank:subvol-151-disk-2,mp=mnt/data2,backup=1,size=500G
mp2: ZFSTank:subvol-151-disk-3,mp=mnt/data3,backup=1,size=500G
net0: name=eth0,bridge=vmbr0,firewall=1,hwaddr=XXX,ip=dhcp,ip6=dhcp,type=veth
onboot: 1
ostype: ubuntu
parent: vzdump
rootfs: local-zfs:subvol-151-disk-1,size=15G
startup: order=1,up=15
swap: 512

ok, I found 1 problem: I restored mp2 accidently to /mnt/data3, it should have be /mnt/data4. I edited the config, but it doesn't work either..

i guess you would have to write the mp like this:

mp0: ZFSTank:subvol-151-disk-1,mp=/mnt/data,backup=1,size=500G

note the leading '/', but i am not sure at the moment

 

[MisterY]

it seems to work right now
