Backup to Disk and then to Tape

I don't know if this is a new suggestion or if this is a capability in Backup Exec that I haven't discovered. When I backup with Backup Exec 2010 R3.  I have some jobs that Backup to Disk, then wit...

     I regularly have to free up disk space to keep the Backup to Disk running

    It is always recommended to configure BE to that instead of doing it manually.

    You have to configure b2d jobs to overwrite because there is no advanteage in appending to disk backups.

    I doubt you are appending now. Set B2D jobs to Overwrite only and configure media sets with 0 hours append period and proper OPP. These settings will ensure proper media management. 

    Also give a read here: https://www-secure.symantec.com/connect/blogs/faq-how-configure-media-setsb2d-jobs-and-backup-exec-proper-management-disk-space-while-using-

    Once b2d jobs configured in such a way, duplicate to tape job will run before the bkf files overwritten in next cycle.

I have 2 TB of disk space to backup to backup most servers.  I have a separate 1TB for our Exchange (the separation made the Exchange backups more reliable).  I don't have the deduplication function either.  The guy who originally configured this server, setup the Jobs where multiple servers are in a single Backup Selection List, then there are Backup Policies for Virtual Servers.  In troubleshooting this server, I keep breaking down the Selection lists to have less servers in each list.  In the older installation of Backup Exec 12.5, I had each server with it's own selection list, and used the policy to backup the servers.  I am starting to wonder if it is better to have a selection list for each server, although it creates lots of jobs. 

I did change the Backup to Disk policy to not append (although Append was a short timeframe).

I am filling up two LTO4 tapes and halfway filling the third LTO4 tape in a weekly full backup.  Roughly 3TB of backed up data from what I can discern.  I am not as worried about the incrementals, but I would like to be able to have a full backup with the current weeks worth of incrementals if I could hold it.

I am OK with keeping the data on disk for a week, but I also have issues with the Backup to Disk being erased before I can even get the incrementals to tape, I don't always get the Incrementals written to tape at times.
