If you want tapes around forever, I think your best bet is to change the 
retention time in the pool to, say, ten years (I'm not sure if you can 
do an infinite retention time off the top of my head). Usually, if 
bacula can manage something, why would you want to do it manually?

That said, to answer your other questions: you actually can recover what 
is on a tape even after the tape has been marked as "purged" in the 
database. The data on the tape is unchanged, and the btape and bextract 
utilities allow you to recover whatever is on the tape, even if it is no 
longer in the database.

In addition to Recycle = no, you may also want to set AutoPrune = no. 
Otherwise, bacula will still delete database records about your tapes. 
You probably should make sure that the fileset resource has a shorter 
retention time than the jobs or volumes in the pool, since the file 
information takes up a lot of space in the database. The bacula manual 
has quite a bit of information on that aspect in the database 
maintenance chapter.
