I seriuosly doubt that you can do anything but reinstall. What happened is that you have overwritten the filesystem layout from the same filesystem you were "backing up" and at that *while* you were backing it up. There shouldn't be anything useful on /dev/rfd0a. You will need to newfs / again and reinstall. With luck your other directories (/usr, /var, ...) are on separate partitions.
