I use sanoid/syncoid to back up using zfs.  Its great, keeps snapshots
for as long as I want them (I use 80 days for now).  And it keeps
hourlies for the last couple of days as well, so I could roll back in
case of a problem.  Very nice if you use zfs.  I don't think btrfs is
ready for prime time -- its been under development for a while, but I
am scared to use it -- I did try once, but got nowhere.
