Lxc copy --refresh workaround: efficient incremental ZFS snapshot sync with send/receive

Hi Florian

Thanks for clarifying your script! On further consideration, I think I’d prefer to backup to a machine with a ZFS pool that isn’t running LXD as I don’t need a hot standby. Might you be able to answer my latest questions regarding LXD and ZFS in this thread?

Lxc image import and ZFS

I’m trying to work out the best (simplest and most efficient) way to backup and restore my ZFS pool backed LXD containers whilst retaining all snapshots intact. I would prefer to do this by backing up the lxd config and using the zfs send command to backup the LXD containers dataset onto a ZFS dataset on a remote machine not running LXD. The backing up bit should be easy enough but it is the restore process I’m not sure about as I’m really hoping to avoid having to create any tarballs for the r…

Thanks!
