Greetings,
Could someone lead me in the right direction on best practice for the B2D option? As in, how long to keep differentials\fulls on disk, backing up the disk to tape? I have searched and not found too much information on it.
Kind Regards,
Mike..

Check this technote
http://www.symantec.com/docs/TECH164267 : Backup-to-Disk Best Practices
In addition to that check the following:
Backup Exec (BE) 2012 adds a new disk management function called Data Lifecycle Management (DLM). This allows BE to correctly manage disk targets and remove expired backup data. The Backup Definition (jobs) have a setting for how long the backup data should be kept. After that timeframe has expired, DLM will delete the backup sets from Disk. DLM checks for any expired data every 4 hours by default.
DLM is only used for Disk targets. Backup to Disk (B2D) and Deduplication.
Tape targets are managed by Media Sets like the previous versions of BE.
