You were the one asking me to look at LVM snapshots, as though they had 
some relevance to the discussion. Do you backpedal from that now?

Presumably you were relying on the applications themselves (e.g. DBMSes) 
to recover from inconsistencies in their data. Things are always easier 
when they’re Someone Else’s Problem, aren’t they?

Fun fact: Andrew Tridgell, who originally created rsync, did his PhD 
thesis on the algorithm it uses that allows two processes on different 
machines to compare two files, one on each side, without having to copy 
the bulk of either one of them over the network to the other side.

Veritas Appliances never had anything like that, did they?
