Sure thing.  The sysresccd iso is obtained from:
http://www.sysresccd.org/

Just modify the scripts to use your appropriate paths and dump utilities
(e.g. if you don't use xfs).   mbr.txt and xfsrestore.txt are just some
notes that I have for restoring those respective backups.   (you should
be able to google for it)
