The other option is LVM snapshots or a filesystem that has snapshots like ZFS. Just don't use ext3 with snapshots on a busy server - it's a horrible performer because it's block-based. Extent-based ones like xfs perform much better and you can "freeze" an xfs filesystem so the snapshot is consistent. This is about MySQL but it has some good information: http://www.mysqlperformanceblog.com/2009/02/05/disaster-lvm-performance-in-snapshot-mode/ And this Ars article describes the basic snapshot procedure for those unfamiliar with it: http://arstechnica.com/open-source/news/2004/10/linux-20041013.ars ~Seth
