Actually, amanda already does that. From man amanda:


chunksize   		     Dumps larger than the speci-
			     fied size will be stored in multiple
			     holding  disk  files.   The  size of
			     each chunk will not exceed the spec-
			     ified  value.   However, even though
			     dump images are split in the holding
			     disk,  they are concatenated as they
			     are written to tape,  so  each  dump
			     image  still corresponds to a single
			     continuous tape section.
