I've been playing with [sanoid] for generating/pruning snapshots on a
remote machine, `syncoid` from the same package for "pull" syncing
from the remote machine to a FreeNAS system, and [sanoid] on the local
backup server solely to prune the snapshots.  It's working reasonably
well (e.g. I just got a weird email (cron) about it failing to remove
something, but it's gone on the next iteration, so....).

I've submitted [a bug report][new-ports] that contains a release port
and a devel port.  Any help getting it committed would be most
welcome.

I also have both ports in my ["personal ports tree"][my-ports], it's
intended to be layered over the full ports tree with e.g. portshaker.
