I want to make a full system backup on a cd-RW.

What software is necessary ? an how to make it ?

Use Joerg Schilling's cdrecord to burn CD's under OSR 5, BUT: you cannot
fit your server's files on a CD-ROM disc, it just is too small.

Well, continue to use a DAT, but use LoneTar or BackupEDGE, not cpio.

First of all, why would you want to do a system backup of whats on a laptop?
Surely you would be better to just backup the essential files you need.
But if you must try. The command to do a full system backup to CD would go
like:-
find / -print | cpio -ovcB > /dev/cd0

Hope this helps

Andre,

You need to have a lot of free space on your file system to
do what you want with cpio.

1) run a find script to create a list of files to be backed
up.

2) cat the files to cpio to create an cpio archive of the files.

3) If necessary, compress the archive to get it below the
700M that you can write to a CD.

4) run mkisofs of the directory holding the cpio archive to
create the CD image.

5) run cdrecord to write the ISOF file to the CD.

Other considerations: You need to install enhanced WD driver
on 5.0.6 to enable CD record to write to ATAPI CD burners.

You need ot install CD record from Skunkware

I have found the following commands to work on 5.0.6

mkisofs -V "SCO 5.0.6 root 07.11.03" -b cdboot.img -R -J /app1/cd3 > /app1/506root.isofs
cdrecord -v -v fs=6m blank=fast speed=4 dev=5,0 /app1/505root.isofs | tee /tmp/logcd 2>&1


/app1/cd3 is the directory holding the ISO image of the root file system
and the bootable cdboot.img.

cdboot.img is my 2.88M Emergency boot image created with a modified mkdevfd
script to write the image to a RAM disk file system and then copied to
the cdboot.img file. Search groups.google.com on "Bootable Recovery CD."

After booting the image, mount the CD and use zcat to uncompress the
cpio backup:

mount /dev/cd0 /mnt1
mount /dev/hd0root /mnt
cd /mnt
zcat /mnt1/506root.isofs | cpio -icvmd

OK, then you have very little on there besides the OS.

Well it helps if that command works for you. Does it really work?

It's part of Schilling's cdrtools suite. I have the last stable release
source code on ftp.jpr.com.
