Actually using Image Catalogs are like using DVD optical media.
Kind of cool, but size somewhat limited. I think each virtual optical can be up to 16gb.
Not sure if that has increased.
The RDX thing is cool as well, but definitely requires the new machine.
Apparently the USB ports on the newer boxes will allow standard memory sticks to be used too :-)

I don't know anything about image catalogs, but from the sound of it,
this would be similar in principle to tar or other archiving formats.
Unix folks are of course familiar with tar, which presumably was
created for exactly this use (it means "Tape ARchive" after all). But
if you can trade some CPU time and temporary disk space for tape I/O
time and tape space, you can use a more modern compressed archive
format, like .zip or .7z.
I also like Nathan's idea of copying only new or changed files, which
is one of the main strategies used by dedicated backup software on
