I think the partitioning will be hard to manage after awhile and what you are trying to do is handled by Media Sets and not partitions.
If you remove the partitioning and just let Backup Exec handle the media you'll be fine. First, set up media sets to what you need.
Full Media Set 5 Days overwrite 2 days append (total 7 days of protection) used for both fulls and incrementals
Monthly Media Set 63 Days (or a 2 months+) overwrite protections. You actually want to not overwrite this until you have another "good" monthly backup.
Yearly Media Set 1 year+ . Again do not overwrite until you have another good yearly.
Second, ask yourself "If the system crashes and I need to recover what's most important to protect and how far back should I restore from?" Do you really need a yearly or monthly backup? Do you need more fulls or can you get by with more incrementals/differentials? How far back can I restore from in the worst case scenario? Lets say you run fulls every night and keep seven days worth, is that better than running one full and 6 incrementals? How much data changes between backups?
To restore from an incremental you will first need the Full and then every incremental in between, but if you ran a full every night, then you would only need that tape. However it would require more tapes. However, to restore from a differential, I only need the Full and the one differential tape.
