Re: Announcement: buttersink - like rsync for btrfs snapshots

[Jim Salter <jim@jrs-s.net>]

How has it been for reliability?

I wrote a btrsync app a while back, and the app /itself/ worked fine, 
but the btrfs send / btrfs receive itself proved problematic.  Since 
btrfs would keep a partial receive - with no easy way to tell whether a 
receive WAS partial or full - I would inevitably end up with interrupted 
sends causing a problem that couldn't be resolved without manually 
deleting snapshots on the target end haphazardly until I nailed the 
incomplete one.
