Suppose you have a scenario where you have multiple disk staging backup jobs or multiple GFS Rotation backup jobs, and each job formats its own tape for incremental or differential backups. If the incremental or differential size of the data is lesser than the capacity of the tapes, the tape usage will not be optimized and space on the tapes will be wasted. In addition, using more tapes will increase the requirement for the number of slots in a tape library and can also result in the need to ship more tapes off-site.
There are two approaches to resolving this problem: Media Maximization and Consolidation During Migration.
