I'm using LVW snapshots. As I see it, very many data files from very many applications will be corrupt in a conventional backup taken while the applications are running. Finding how to safely back up each one (i.e. the equivalent of svn hotcopy or psql-dump) would be very time-consuming and error prone. LVM snapshots take the approach of solving the problem at the filesystem level: you backup a "point-in-time" image of the filesystem.

I asked on this list a few months ago to see if other users had any experience with or comments about the approach, but didn't get much response. It is working well for me, and I would still be interested to hear of others' experiences of this and other backup techniques.
