Thanks Alex, I've never heard of rsnapshot tool. We got rsync all started
when we were using Gentoo, but have since moved to CentOS. Right now I have
seperate scripts for hourly, daily and weekly. The hourly does all the heavy
lifting, with daily and weekly being simple scripts that makes hardlinks
from all the hourly snapshots. All in all, it's pretty cool. Never have to
flip tapes everyday in the tape library, works on holidays without missing
backups and restores happen at network speeds. If you've ever tried to pull
100GB off of AIT3 tapes, you know what I'm talking about.
