this looks great:

"kCDrec makes a bootable (El Torito) disaster recovery image (CDrec.iso),
including backups of the linux system to the same CD-ROM (or CD-RW) if space
permits, or to a multi-volume CD-ROM set. Otherwise, the backups can be
stored on another local disk, NFS disk or (remote) tape.
After a disaster (disk crash or system intrusion) the system can be booted
from the CD-ROM and one can restore the complete system as it was (at the
time mkCDrec was run)"

I think this is exactly what I´m looking for
