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. Mark
