should backup-dir be INSIDE the sync'd folder?

Meh. rsync does the job well enough, I just wrote scripts for it.

Yeah, that seems to work.

Maybe, I guess. But it didn't look like it. I had verbose mode on, and it
appeared to keep freezing part way through uploading a file. But it was a
different file every time I ran it. If it happens again I'll investigate
Anyway, I basically started again, downloaded a new copy of the folder using
the --times option, and now it seems to be working fine.
I'd just like to thank everyone involved for the rsync program. It's a very
useful little tool, it's helping me keep my work safely backed up with
barely any effort and I expect I'll be using it throughout my three years of
