Media Server Deduplication Pool storage unit properties
The following are the configuration options for a storage unit that has a as a target.
Table: Media Server Deduplication Pool storage unit properties
| Property | Description |
|---|
|
Storage unit name
|
A unique name for the new storage unit. The name can describe the type of storage. The storage unit name is the name used to specify a storage unit for policies and schedules. The storage unit name cannot be changed after creation.
|
|
Storage unit type
|
Select as the storage unit type.
|
|
Disk type
|
Select for the disk type for a .
|
|
Disk pool
|
Select the disk pool that contains the storage for this storage unit.
All disk pools of the specified appear in the list. If no disk pools are configured, no disk pools appear in the list.
|
|
Media server
|
The Media server setting specifies the NetBackup media servers that can deduplicate the data for this storage unit. Only the deduplication storage server and the load balancing servers appear in the media server list.
Specify the media server or servers as follows: To allow any server in the media server list to deduplicate data, select . To use specific media servers to deduplicate the data, select . Then, select the media servers to allow.
NetBackup selects the media server to use when the policy runs.

|
Maximum fragment size
|
For normal backups, NetBackup breaks each backup image into fragments so it does not exceed the maximum file size that the file system allows. You can enter a value from 20 MBs to 51200 MBs.
For a FlashBackup policy, Veritas recommends that you use the default, maximum fragment size to ensure optimal deduplication performance.

|
Maximum concurrent jobs
|
The setting specifies the maximum number of jobs that NetBackup can send to a disk storage unit at one time. (Default: one job. The job count can range from 0 to 256.) This setting corresponds to the Maximum concurrent write drives setting for a Media Manager storage unit.
NetBackup queues jobs until the storage unit is available. If three backup jobs are scheduled and is set to two, NetBackup starts the first two jobs and queues the third job. If a job contains multiple copies, each copy applies toward the count.
controls the traffic for backup and duplication jobs but not restore jobs. The count applies to all servers in the storage unit, not per server. If you select multiple media servers in the storage unit and 1 for , only one job runs at a time.
The number to enter depends on the available disk space and the server's ability to run multiple backup processes.
A Maximum concurrent jobs setting of 0 disables the storage unit. |
Use WORM | This option is enabled for storage units that are WORM capable. WORM is the acronym for Write Once Read Many. Select this option if you want the backup images on this storage unit to be immutable and indelible until the WORM Unlock Time. |
