Are you "taping" to virtual tapes on hard disk?  If so, and your version
of amanda is recent, us the tape splitting feature that writes in chunks
than can, but don't have to, span several tapes.

If using a holding disk, use the chunk size feature to limit the maximum
size of a file on holding disk.
