Creating GFS Tape Jobs
To create a GFS archive on tape, you need to create a GFS media pool and target a backup to tape job to it. Technically, a GFS tape job is a variant of backup to tape job. When you select a GFS media pool as target, the job schedule automatically changes to the GFS mode. For details, see Creating Backup to Tape Jobs.
As a source, you can use a backup job with any backup method: forever forward incremental, forward incremental or reversed incremental.
If you use a job with enabled GFS retention as a source for a GFS tape job, the GFS tape job writes restore points to tapes according to its own schedule. The schedule of the source job is not taken into account.
