I find the cost of CD-R media and DVD+R, as well as the issues with
longevity, to be my biggest concerns. For those types of media,
having a very robust and redundant easy to recover format would be
key. Haven't seen it done yet, though it's been talked about. An
Archive filesystem, not a general access one.
Let me make one comment on that. To back up files of reasonable (<1GB)
files, you can build a list of files which will fit on a single DVD (a
series of lists actually), and backup the files to a DVD, either in ISO
format or using the loopback mount to make an ext2 filesystem you can
write to a DVD, or a tar, cpio, you get the idea. The tool to make the
lists of files which will fit is "breaker" and is on
www.tmr.com/~public/source for your enjoyment.
The other tool is dvdisaster, which builds software ECC for images you
are going to burn. You can make DVDs with 3.3GB data + ECC on each DVD,
or 4.4GB data per DVD and keep the ECC files separately, whatever
pleases you. The recovery mode does work, I used scissors to scratch a
DVD with my initials, then recovered the data.
Both programs have enough documentation for most users.
