I suggest using afio. It compresses single files, not the whole archive,
which makes the backups less vulnerable. It is compatibel with cpio.

I would compile this into the kernel (not as module).

You do not need to mount a disk to used it with cdrecord and mkisofs.
What do you do with a blank disc?
,----[ mount /cdrw ]
| mount: wrong fs type, bad option, bad superblock on /dev/cdrw,
| or too many mounted file systems

Where is dev=0,0,0?
,----[ cdrecord fs=4m -dummy -v -multi ~/../image-dir/Backup_31_08_2002.iso ]
| cdrecord: No CD/DVD-Recorder device specified.

| Use cdrecord -help

| Use cdrecord blank=help

See above.
