This tool appears to be a popular Open Source disaster recovery suite for Linux (and Windows FAT32). Anyone tried this?
http://www.microwerks.net/~hugo/ What is Mondo? Mondo is reliable. It backs up your GNU/Linux server or workstation to tape, CD-R, CD-RW or NFS partition. In the event of catastrophic data loss, you will be able to restore all of your data [or as much as you want], from bare metal if necessary. Mondo is in use by Nortel Networks, Siemens, HP (US and France), IBM, NASA's JPL, dozens of smaller companies, and tens of thousands of users. Mondo is comprehensive. Mondo supports LVM, RAID, ext2, ext3, JFS, XFS, ReiserFS, VFAT, and can support additional filesystems easily: just e-mail the mailing list with your request. It supports adjustments in disk geometry, including migration from non-RAID to RAID. Mondo runs on all major Linux distributions and is getting better all the time. You may even backup non-Linux partitions. Mondo is free. It has been published under the GPL (GNU Public License), partly to expose it to thousands of potential beta-testers but mostly as a contribution to the Linux community. I fund its development by charging for technical support.
