All, thanks!

Nope, I wouldn't think of changing anything inside a backup repo.  Since it
seems to work with the right permissions and ownership in repos, my only
real question is whether the 777 on the owned-by-me partition and the 755
on the owned-by-me backups directory  would get me in trouble at some point.

I get the point about saving /home as its owner, but that would have
required me to figure out how to suid better and how to do it without
saving passwords in cleartext or asking for password entry at various
times.  This seems to work, and I haven't heard a showstopper objection yet.
