OpenStorage storage unit properties

The configuration options for a OpenStorage disk pool storage unit are as follows:

Table: OpenStorage storage unit properties

Property

Description

Storage unit name

Provide 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 OpenStorage (Solution) for the disk type. Solution is a string provided by the storage vendor that may represent the vendor, the vendor device, or something else that is meaningful.

Disk pool configured for

Select Backup for the disk type.

Replication source

Select this option to filter the available disk pools to show only those that contain replication source volumes.

Replication target

Select this option to filter the available disk pools to show only those that contain replication target volumes.

A disk volume can be both a replication source and a replication target.

Disk pool

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

If you select a replication property, NetBackup filters the disk pools that appear in the Disk pool list. Otherwise, all disk pools of the specified Disk type appear. If no disk pools are configured, no disk pools appear in the list.

After you select a disk pool, you can click View Properties.

Media server

Specify the NetBackup media servers that can move data to the storage server for this storage unit. (For OpenStorage, NetBackup media servers function as data movers.)

Only the media servers that are configured as data movers for the OpenStorage implementation appear in the media server list. If a media server does not appear in the list, verify that the software plug-in is installed and that logon credentials are created.

Specify the media server or servers as follows:

  • To allow any media server in the media server list to move data to the storage server, check Use Any Available Media Server.

    If you configure more media server data movers in the future, you do not have to update the storage unit. After you install the plug-in and configure the credentials, NetBackup automatically uses the media servers for the backups that are sent to the storage unit.

  • To restrict the media servers that can move data to the storage server, check Only Use The Following Media Servers. Then select the media servers that are allowed to move the data.

Any media server in the list can receive data from the storage server; it does not have to be selected. A media server receives data for restore jobs and for storage monitoring purposes.

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

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 up to the last checkpoint are retained; the fragments after the last checkpoint are discarded.)

Maximum concurrent jobs

Specify 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.)

NetBackup queues jobs until the storage unit is available. If three backup jobs are ready to be sent to the storage unit and Maximum concurrent jobs is set to two, NetBackup starts the first two jobs. NetBackup 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.

See About throttling OpenStorage traffic to the media servers.

Use WORM

This option can be 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. The indelible property is set until the WORM Unlock Time.
