[nflug] Image backups

[Joe]

I have shell scripts for my ancient desktop that create image backups of
my Linux and Windows partitions and burn them to CDROM's using dump for
Linux and partimage for Windows.

I want to adapt these for use on my new (dual boot - kubuntu feisty/win
XP) notebook with a single layer DVD burner (and much bigger disk
partitions).

Do I keep everything the same, just making the iso files much larger or
do I need a new method of doing things?

The current script does a:
/sbin/dump 0uMBzf 614400 <target-drive> <source-drive>

for each Linux (ext2/3) partition and a

/usr/sbin/partimage -V614400 -z1 -o -d -m -b  -f3 save  <source-drive>
<target-drive>

for each Windows (FAT32) partition.  Then, I just run a script that
burns all the images in the order I wanted them while I do a protracted
CD shuffle.

How many blocks big is a DVD or do I have to do things entirely
differently?  My new notebook uses ext3 and NTFS.

TIA

P.S. I just extracted the lines of code that make the backups and
removed variable references to make it more clear.  I'd have to pour
over the man pages to remember what all the options mean.  The whole
scripts are available if anyone wants to see them.
