AFAICT, duplicity differentiates between incremental and full backups,
which means that periodically we'd need to make a new full backup
instead of having to step through every incremental backup. That's
fine I guess, but I'd rather have full backups with deduplication,
like tarsnap or bup. Of course, tarsnap is nonfree, and bup is
immature.
(+10 internet points to whoever writes a Free clone of tarsnap.)
But also: I think the more important question to answer is "where does
the data go"? Where will we host it?
