    Depends on your exact needs - you can create a separate volume pool and limit it to 3 partially full tapes. If you allocate this one backup to that pool, it wil do what oyu need.

    As you write the backups to tape it will only use 3 at a time,so you will fill three and always have multiples of 3 tapes.

    Essentially you are not using the other 7 drives for this backup.

    There are issues with tape usage when creatig too many volumne pools though

Nicolai is correct, it is possible but messy.

NBU + associated hardware costs $$$ - tapes are very very cheap.

NBU is complex these days, but going back to basics all backups went to tape, and NBU was designed to manage tapes and it does this very very well.  Use this feature - get plenty of tapes, throw them at NBU and forget about it, that is what it is designed to do.
