Thanks for the suggestion, but it seems a fairly heavy-weight solution.  It's
got a snapperd that runs from dbus (a daemon?) and a command line utility to

overhead when you just want BTRFS.

Maybe not much use for you, however here is a solution that is LVM specific (and also uses a naming convention that is compatible with the Samba Volume Shadow Copy interface)
