I still think that if these are year-at-a-time folders that never change 
once the new one has been created, your obvious solution is to back them 
up as *separate jobs* for each annual folder.  You can do incrementals 
and periodic VirtualFull backup jobs over the course of the year, then 
when the folder gets replaced, do one final Full backup of THAT FOLDER 
ONLY on a separate tape, mark it as an archive, write-protect the tape, 
and set it aside somewhere safe.

(A VirtualFull backup uses the contents of previous Full, Differential 
and Incremental jobs to create a "synthetic" full backup that you can 
restore from as a single job, without re-backing up all of the data again.)
