I think what you really want is something like "rdiff-backup" or 
"duplicity". Both tools let you maintain backups with history, remove 
old revisions, etc. You can indeed store the archives in mysqlfs if you 
wish.

Have a look at:
- http://www.nongnu.org/duplicity/
- http://rdiff-backup.stanford.edu/
- http://www.debian-administration.org/articles/209 (not really 
debian-specific, don't worry)

HTH.
