Yes, you can force rdiff-backup to do a regression of the most recent backup
just as it would do automatically if the most recent session had not run to
completion.  Basically, within the rdiff-backup-data metadata directory you
create a second current_mirror.{timestamp}.data file with a timestamp that
matches the mirror_metadata file for the immediately preceding backup.

Dominic Raferd has written a script that will automate that and take care
of various "gotcha"s that can arise.  It's attached to this message in
the mailing list archives:

Here's a direct link to the attached script:
