[lxc-users] Correct way to rsync /var/lib/lxd

[Mark Constable]

I'm just trying to do a simple rsync backup of /var/lib/lxd/ to a local NAS and get
these errors as root on the host. I understand the issue of subgids and subuids not
being valid on the target machine (the below errors are coming from the destination)
outside the normal range of uid/gids but I'm still not sure of the best flags, if any,
to provide for rsync to get around this? Or is there a better way to backup containers?
