What I primarily rely on for my backup strategy, however, is volume
mirroring.  You can have a volume live on two or more AFS file servers
(in my case, one in my office and the other in FRII's co-lo), so that's
what I use for all critical data (work files).

Did I mention AFS is open source?  http://www.openafs.org/
