Longer than normal backup time when switching from append to overwrite mode.

Is it normal for the job to take longer when switching from append to overwrite? We are running 11d using B2D. Jobs are taking 1.5 times longer when they switch from append to media and go to overwriteable media.
Hi Christopher, Yes and
Hi Christopher,
Yes and no.
When using Append, it's going to add data onto that tape until it cannot anymore. The tape then gets write protected as per your retention policy.
When using Overwrite, the data gets written to the tape, and then write protected. When it's made available to scratch media, the tape is then erased. This is the only time it should be adding to your backup times.
With you running this to disk, it could be taking a longer time to erase the B2D file, and make it available.
Laters!
