About robotic library partitions

You can group one or more robotic library slots into partitions. Partitioning robotic library slots provides you with more control over which tape is used for backup jobs. When you create robotic library partitions, Backup Exec creates a storage device pool for each partition. Jobs that you send to a partition's storage device pool run on the media that is located in the partition's slots. For example, if you set up a partition that contains slots 1 and 2 and you want to run a weekly backup only on the media in these slots, you would submit the job to the storage device pool for the partition that contains slots 1 and 2. The storage device pools for robotic library partitions appear in the drop-down menu for the Storage field when you edit the backup job. All storage device pools for a robotic library partition have the same name and display the slot ranges for the partition in parentheses within the name.

Partitions can include any number of robotic library slots. However, you cannot move or delete the first partition when other partitions exist.

Depending on the robotic library configuration, the first slot may be numbered 1 or 0. If the robotic library uses a zero-based slot configuration and you assign the first partition to begin with slot 1, the Partition Utility will actually use slot 0 as the first slot for partition 1 and adjust the starting slot accordingly for all other partitions.

When the robotic library is partitioned, Backup Exec searches for the oldest recyclable media in the targeted partition only. If more than one media is found that meets the requirements, Backup Exec then selects the media in the lowest-numbered slot; for example, media in slot 2 is selected before equivalent media in slot 4.

You can create a partitioning scheme that best suits your environment. For example, some administrators may create partitions based on users and groups, while others may create partitions according to operation types.
