Notes on a few of the programs I have considered:
Clonezilla doesn't know how to span to DVD's.
Promising newcomer Aomei Backupper has no stated support for ext4
partitions.
Redo Backup is a front-end for partclone, and I have seen no
documentation indicates that it supports spanned DVD's.
In short, everything that I have looked at in the past or now in a
fresh
new sweep falls short on one point or another.
I'm willing to fudge on my desire for a single image-the-disk
operation
if I could find a recipe or documentation on how to use a
partition-oriented tool with a script that uses several succeeding
operations to build a complete drive backup. Needless to say, I would
want to arrive at both backup and restore scripts.
Hi John,
Clonezilla creates 2 GB chunks, which can be copied to DVDs and file
systems in general, that cannot manage files larger than that. I don't
know (haven't tried) to write the image directly to DVDs, but it would
certainly be possible in a two-step procedure (with intermediate
storage
in an external HDD or flash drive).
Best regards
Nio

I don't really trust DVD disks for backup, but that is another issue.

Hi, Nio.
Yes, I was aware that I could do such a restore in two steps, and have
used that setup at least once. But I wanted the cheapest, simplest
thing to give away with a computer to someone with no more than average
skills. ("Just boot with this .....")
I have had a fair amount of exchange about this on the Ubuntu users
forum, much of it exploring the idea of using dd in conjunction with
utilities that zero-fill free space (as a preliminary step) and then
compress and split the resulting dd archive. But that idea stalled at
the point where there was no apparent way to input the DVD splits to dd
during a restore. (Also a challenge with removing the boot disc and
replacing it with a data disc, but I imagined that could probably be
solved with a small distro that boots to memory.)
After I last posted there, I also encountered PING, which may possibly
do what I wanted, at least on a dual boot setup with Win Vista. But it
and its backend partimage are apparently no longer under active
development, and people report some problems with Win 7, so I already
regard it with less enthusiasm and have not had a closer look. (But
interesting to note that partimage is one of the alternate backends
employed by Clonezilla, so they must think it is reliable for certain
purposes.)
I've concluded that, for the moment, I can't get quite what I was
looking for. My choices are among half a dozen solutions that are a
compromise on one goal or another.

Hi again John,
I see your situation. How much data is it (compressed)? Would it be
possible to squeeze it into a reasonably cheap USB pendrive?
Best regards/Nio
I looked at that. As I recall, the drive image of the dual-boot
installation with maximum compression was over 20GB (the lion's share of
that due to the Windows Vista partition -- I think I can probably still
get my usual Lubuntu-only installation onto a single bootable Clonezilla
DVD). In any case, I remember that a 16GB drive would not do -- I would
have to move up to a 32GB drive.
The cheapest (and rather slow) 32 GB pendrives cost approximately
18 € or $ 24 in my country. There is a 'pirate tax' on DVDs so seven or
eight of them cost a significant sum too.
$20-25 would be a decent price for the 32 GB drive here. Compare that
to the 5 image DVD's I would need for the same installation. A Verbatim
50-pack of DVD's I can get here for about $0.30/DVD, so cost of the DVD
set would be about $1.50.
That's a big difference, especially for something to give away with an
older computer. It's a backup measure that many people will never need,
and it doesn't justify too many $$.
