I do this as well, and it works great. Another way to do it is using rdiff-backup, which is fairly well tested at this point. It takes a lot less space than hardlink snapshots if you have huge files that change just a little on a regular basis (like a big database). It's much more complicated than hardlink snapshots, though, so more things can go wrong. If you use LVM snapshots (still marked "experimental" in the newest kernel but seems to be stable), I *believe* you can even trust that things like live databases will have a valid backup, assuming your database has a journal like Postgresql. If that's wrong, someone pipe up. Although I do daily database dumps as well, I haven't thought of a reason why LVM snapshots of the database directories in /var/lib shouldn't be flawless (assuming a database journal).
