you can substitute cpio for dump in what you planned to do and it will work, that will give you a filesystem rather than block-level copy of the contents of your disk, it's still not safe for some running applications like databases but under most circumstances it works pretty well.
There is also I believe a dump-safe version of xfs out there.

I should have supplied more details. My requirements are minimal. I have two machines (1 - FC4, and 1 - XP) that I'd like to back up. I don't need any archival on either machine. My primary concern is hard disk failure. FC4 box requirements: The FC4 box is running several websites with accompanying mySQL db's. The websites are all maintained under individual logins, under /home Everything else on the machine could recovered easily enough, so the only backups would be of /home and the mySQL db's. I've gotten the XP backup worked out. I use the Windows backup utility to a mapped Samba drive. (Which works fine for me.) I do a repeating cycle of 1 complete backup followed by 6 incremental backups, done daily. Then I re-use the same files every 7 days. In the event of a drive failure, I don't mind being down for a bit (even a few days), but I'd hate to lose any of my content.
