According to
http://www.fedoraproject.org/wiki/FC5Future

is a back up feature considered, and I would like to suggest rsync
http://samba.anu.edu.au/rsync/

for this with the following arguments
rsync -avWHRx --delete --delete-excluded --log-format='%i %f %l'
--exclude-from=$(HOME)/.rsync-exclude-list source destination

# -a                    symbolic links, devices, attributes, permissions,
ownerships etc are preserved and recursive dirs.
# -v                    verbose
# -R                    relative
# -W                    whole files
# -H                    presurve hardlinks
# -x                    one file system
# --delete              delete files on dest side, that aren't on the src side
# --delete-excluded     also delete excluded files on receiver

After such back up, can the partition be made bootable and boot. So exact is it.
