Want to know how other Linux users back up their systems? Linux-Backup.net, while a tad jarring on the eyes, has scripts and links.

I've mentioned Mondo Rescue before, and only today decided to try it out. It's fantastic, especially for CD-R backups, just run it and drop in the blanks. The backups it makes are bootable for recovery purposes. Do a whole machine, or just specific directories. Other backup media are supported, of course. The development team appears to have a (probably justified) bias against Debian Linux, which I'm running. Debian does come with Mondo, but (as is typical for Debian) the older version 1.4x. My Debian install did not have ramdisk support in the default kernel, but otherwise running a backup was a delightfully smooth process. This is easily something I can do once a month, like I ought to be doing.
