Is there a reason you can't simply back up /Storage?  Is there anything 
under /Storagen that you DON'T want backed up?  Can you make that job 
use a Fileset that excludes the directories under /Storage that you 
don't want to back up?

Is there a reason not to make each folder its own Job, in which only the 
newest will ever see any significant backup data volume?  This avoids 
the problem of the first full backup taking a very long time to run. 
Each year you create a new folder and generate a new read-only archive.


There's probably multiple ways to approach this problem, but it doesn't 
sound difficult.
