Hello
Recently i had to do a disaster recover of my lxd installation, i don’t have individual backups of the containers i only have the folder (/var/snap/lxd/common/lxd) content.
The previous and the current installation version of lxd is 3.0.0
After restoring the folder when i try to start a container i ged this error:
ivan@ti:~$ sudo lxc start ha
Error: Failed to run: /snap/lxd/current/bin/lxd forkstart ha /var/snap/lxd/common/lxd/containers /var/snap/lxd/common/lxd/logs/ha/lxc.conf:

After viewing this link: https://github.com/lxc/lxd/blob/master/doc/backup.md , i’m assuming that the folder restoration was enough.
Does anyone have any ideia how do correctly restore the lxd setup,.
Best regards.
