Backup Exec 2014 Question

Hi,

  I have a problem for you.

We use Backup Exec 2014.  It is all patched and updated to the most current version.  
The OS is Window Server 2012.  
The tape drive we use is a Dell ML-6000.

We have to keep our tapes for 1 year then we can recycle them to use over again.  We do incremental backups M-F and full backups on the weekend.

Here is the problem, whenever BE2014 gets a tape from scratch media, it moves it to the media set of “Keep 1 Year”.  I will only write to the tape once.  It is a LTO 4 tape that can hold 800 gig uncompressed or 1.6 TB compressed.  So, it will write an incremental of 120 gigs to the tape and the next night I will grab the next tape out of scratch media.  

When I go to backup options, and select storage, I have it set to Overwrite Media.  My other two choices are Append to media, overwrite if no appendable media is available, and Append to media, terminate job if no appendable media is available.

When I go and look at the three tapes that have been written to once, it says,

Tapes 100    
Overwrite Protection = Infinite, Do not allow overwrite  
Append Until = Infinite, Allow append  
Capacity = 106 GB of 745


Tape 110
Overwrite Protection = Infinite, Do not allow overwrite  
Append Until = Infinite, Allow append  
Capacity = 26 GB of 745


Tape 120    
Overwrite Protection = Infinite, Do not allow overwrite  
 Append Until = Infinite, Allow append  
Capacity = 56 GB of 745

I want to utilize all the space on the tapes before it grabs another tape out of scratch media.  
What is going on now is just a waste of tape space because the whole tape is not being utilized.
