I got daromizer to produce and burn one (smaller) slice. Could not coax it
into continuing from there.
I have a feeling that having to load all three disks is part of dar's method.
Mondo keeps a catalog so may be better and also does the whole job. Has
numerous command options similar to dar. One can write script once to take
care of original and for differential backups. Also produces bootable media.
However, it shares the same problem. One must have the whole 4.5 gig available
for the image and it takes all day to make that one. Has 9 different
compression levels and apparently can use lzo.
