AdvancedDisk storage unit properties

The following are the configuration options for a disk pool storage unit.

Table: AdvancedDisk storage unit properties

Property

Description

Storage unit name

Enter 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 Disk as the storage unit type.

Disk type

Select AdvancedDisk for the disk type.

Disk pool

Select the disk pool that contains the storage for this storage unit.

All disk pools of the specified Disk type appear in the Disk pool list. If no disk pools are configured, no disk pools appear in the list.

Media server

Specify the NetBackup media servers that can move data to and from the disk pool for this storage unit. Only the media servers that are configured as storage servers appear in the media servers list.

Specify the media server or servers as follows:

  • To allow any server in the media server list to access the disk storage (default), select Use any available media server.

  • To restrict the media servers that can access the disk storage, select Only use the following media servers. Then, select the media servers to allow. The selection list includes only the media servers that are configured as storage servers for the disk pool.

NetBackup selects the media server to use when the policy runs.

Maximum concurrent jobs

Specify the maximum number of write 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 tape storage unit.

NetBackup queues jobs until the storage unit is available. If three backup jobs are scheduled and Maximum concurrent jobs 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 Maximum concurrent jobs count.

Maximum concurrent jobs 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 Maximum concurrent jobs, 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.

Warning:

A Maximum concurrent jobs setting of 0 disables the storage unit.

Maximum fragment size

Specify the largest fragment size that NetBackup can create to store backups.

The default maximum fragment size for a disk storage unit is 524,288 megabytes. To specify a maximum fragment size other than the default, enter a value from 20 megabytes to 524,288 megabytes.

Backups to disk are usually fragmented to ensure that the backup does not exceed the maximum size that the file system allows.

If an error occurs in a backup, the entire backup is discarded. The backup restarts from the beginning, not from the fragment where the error occurred. (An exception is for backups for which checkpoint and restart are enabled. In that case, fragments before and including the last checkpoint are retained; the fragments after the last checkpoint are discarded.)
