I wonder if anyone would be interested in creating a launcher for Personal-Backup. It can be found here http://personal-backup.rathlev-home.de/index-e.html.
I don't believe it is OSS, (the legal stuff is in German) so (as I understand) only a launcher could be released, but it is free and gives instructions on how to run from USB with command-line options.
While I use Toucan there are always different strokes for.. you know.
Just a suggestion.
