Well, I was able to run --list-increments before to see all the
previous backups, but now I'm getting an error when doing anything
with rdiff-backup.

"Fatal Error: Previous backup to /Volumes/Backup320 seems to have failed.
Rerun rdiff-backup with --check-destination-dir option to revert
directory to state before unsuccessful session."




Here's what I get with -v8 and -r 0B:

When I run "--check-destination-dir" I get more errors:

Hm, I'm on Leopard... there's an option called "Ignore ownership on
this volume" which sounds like the same (Tiger?) option. It is not
checked.

Should I just cut my losses and reformat the backup drive and start
over? I'm getting those errors with any rdiff-backup command that's
run.
