How You Can Maximize the Use of Media

To take full advantage of the Media Maximization option, use the following guidelines when submitting GFS backup jobs using the same media pool:

Use the same Rotation Scheme--GFS jobs that use different rotation schemes may need different tape names. To ensure that multiple GFS jobs will share the media, use the same rotation scheme.
Start GFS jobs on the same day--The first day of a GFS job is a full backup. Jobs that start with different dates may not be able to share media during the first week. To ensure that multiple GFS jobs will share media during the first week, start GFS jobs on the same day. Otherwise, media sharing will begin after the weekend.
If you want to modify multiple GFS backup jobs to use a new media pool, modify them on the same day--This ensures that all jobs will share the media right away. Otherwise, media sharing will begin after the weekend.
Modify existing GFS jobs to use the same media pool as other GFS jobs--If the existing GFS jobs you modified use the same rotation scheme, media sharing should begin right away. However, if any of the jobs have been running for less than one week, media sharing may begin after the weekend.
