Pretty much any backup software should allow you to do this, as long as the tape is big enough. There should be an option somewhere in your backup to either overwrite or append to the tape. I wouldn't try this with a 20/40GB tape...that 40 is with an assumed 2 to 1 compression ratio, most tape compression I've seen is usually closer to 1.6 to 1.
