Problem is part (3) - if they are not deleted, there is after while no free space on the RAID. The backup files may be overwritten by BackupExec, but this slows down the system extremely.
?? it should be faster, since you don't have the overhead of creating each BKF file
AFAIK, there is no way to "auto delete" bkf files from within BackupExec
I suppose you could place a POST job with the DUPLICATE to tape that executes only on success which would execute a command file to delete all BKF files in the B2D folder
The problem with that is that BackupExec would still think that they are there, and list then in the catalog as active media
