Oh, there is, using the -r syntax (like "-r now").  But since you were
backing up locally I thought cp would be easier for you.

I see.  Right now there is no way to tell it "restore only the files
that have changed in these directories".  That is an option that could
perhaps be added (maybe in 1.1.x) but currently does not exist.  But I
think this is just a matter of speed and not functionality.  If you've
deleted files in /foo/bar and the backup is /backup/bar, you could

    rm -rf /foo/bar
    rdiff-backup -r <time> /backup/bar /foo/bar

Now, for the special case where the files are current in the mirror,
you CAN just restore the changed files, by using a mirroring tool:

    rsync -aH /backup/bar /foo/bar


    rdiff-backup -m /backup/bar /foo/bar

I think perhaps I am not understanding your question again.  When you
restore you don't destroy anything, you just retrieve the information
from the archive and save it somewhere.  To recover a file or
directory you can run rdiff-backup on the associated increment or use
the "rdiff-backup -r <time> file" syntax.
