John,

Thanks for the reply.  I will give that a try and work on a script that will
tell me the next two tapes I could use based on the last written date.

Bacula can not do this because it only recycles volumes when a volume is
needed. Before running a job it does not have any idea how many volumes
would be needed. One way for you to figure out what tapes it will ask for is
to sort your destination pool by lastwritten.
