Using Ubuntu 20.04; zfs and latest stable snap package of LXD.
We have prod. servers with SSD zpools running the containers and a backup server with HHD zpool to collect and store daily snapshots from the former.
Snapshots are created on the prod servers via
lxc snapshot and purged after a couple of days. On the backup server the snapshots remain for a longer time as historical backup.
I wonder if this behavior could be replicated with pure lxd tools.
lxc copy transfers a container and all the actual snapshots to the backup server wonderfully; but it also deletes old snapshots on the backup side which were purged on the prod. server side.
Can I avoid that somehow?
Any other ideas for this use-case?
