And if you want to do it in a text terminal:
Task: Save /home/gonzalo on a multi-session CD-R
Pre-Task: Determine which device is your CDRW:
Open a text console (xterm) and su to root.
Type: cdrecord --scanbus
The output shows your device in the format 0,0,0. You only need the
second and third number.
# cd /home/gonzalo
1. Make an image of the data:
# mkisofs -R -L -T -o foo.raw /home/gonzalo
where 'foo.raw' is a given name whatever suits you, the date of
the backup like 10192002.raw as example.
2. Burn this image as first track on a new CD-R:
# cdrecord -multi -v speed=2 dev=0,0 ./foo.raw
where 'dev=0,0' is the device you determined earlier.
And you can of course change the speed!
3. Determine Start and End of the track:
# cdrecord -msinfo dev=0,0
which puts out 2 numbers like this:
start,end
4. Make an image for the next track:
# mkisofs -R -L -T -C start,end -M 4,0 -o foo.raw /home/gonzalo
where you need to put in the 'sart,end' numbers you determined in
step 2. And you may change the name 'foo.raw' into something
sensible.
5. Burn next track:
# cdrecord -multi -v speed=2 dev=4,0 ./foo.raw
After that you can go on by repeating steps 3 to 5
Thats what I'm doing all the time (if I'm not too lazy)
