It'd be nice to take a backup once a week or once a fortnight, but the
data doesn't change often.  Generally I just add more photos to the
collection.

Not much.  JPEGs don't compress.  There is less mail, but that could
compress quite well.

I'm a bit concerned about storing data in a compressed format, ever
since I backed up my minix partition onto floppies (circa '90) and one
sector on floppy #4 died, resulting in a completely unrecoverable
backup.

Interesting.  Is that 8GB of real storage or compressed?
