Some kind of success: I mv'd the backup directory that backup-rdiff created out of the way, and repeated the backup, with a few extras to, before and after, show what files /dev/sd* existed and/or mounted.

This time it all seems to have worked, except for a few odd messages:

Warning: modification time of b'/usbackup/backup-by-rdiff/april/farhome--hendrik/dn/dosgames/Truelove/rdiff-backup.tmp.234919' isbefore 1970

The files it's trying to back up seem to be dated in 1916 or 1919. Suspicious, but not likely a backup failure. Maybe I should change their dates to something valid, like early in 1970?
