Linux image copy on CD(RW)

I'm looking for a script (or two) that is able to make a:

1) bootable CD with the contents of my Linux Redhat 8.X harddisk, wich can be used to restore after a disaster or restore/ install on another machine.

2) regular databackup on CD/RW, which should run every night to backup/append the data on a CD

Thanks in advance

I have spent some hours some time ago sorting out my CD-RW device. Here are some short notes on what I uncovered:

This was on a slackware 8.1 box

1) Kernel compiled to include all the following options:

* Block devices
o turn ON Loopback device support
* ATA/IDE/MFM/RLL support
o IDE, ATA and ATAPI Block devices
+ turn OFF IDE/ATAPI CDROM support
+ turn ON SCSI emulation support
* SCSI support
o turn ON SCSI support
o turn ON SCSI CDROM support
o turn ON Enable vendor specific extensions
o turn ON SCSI generic support
* File Systems
o turn ON ISO 9660 CDROM file system support
o turn ON Microsoft Joliet CDROM extensions

2) cdrecord downloaded as part of cdrtools
3) Determine what device the SCSI burner is:

root@brezhnev:~# cdrecord -scanbus
Cdrecord 1.11a24 (i686-pc-linux-gnu) Copyright (C) 1995-2002 J�rg Schilling
Linux sg driver version: 3.1.24
Using libscg version 'schily-0.6'
scsibus0:
0,0,0 0) 'LITE-ON ' 'LTR-48125S ' '1S02' Removable CD-ROM
0,1,0 1) *

0,3,0 3) *
0,4,0 4) *
0,5,0 5) *
0,6,0 6) *
0,7,0 7) *

4) script written which uses cdrecord to convert from mp3 to cdr format and pipe the new file contents to a write process:

root@brezhnev:~# cat ~/bin/mkcd
#!/bin/bash
for I in *.mp3
do
mpg123 --cdr - "$I" | cdrecord -dev=0,0,0 speed=0 -audio -pad -nofix -
done
cdrecord -fix

5) Oddly, the CD created wouldn't play, but running a second 'fix' process seemed to partially help.

6) burning a data cd is easy. I have done the 6 cd's required for redhat 9, using the following oneliner:

cdrecord -v speed=0 dev=0,0,0 -data imagefile

------


note that all this is run in a terminal over my network, because the cd burner is in a headless box. You might find some tools likd xroast et al are helpful.
