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

(+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?

Happy hacking,
