Disk storage unit considerations
NetBackup permits the creation of an unlimited number of disk storage units.
Table: Disk media descriptions describes the different disk types that NetBackup can use as disk media.

A disk type storage unit is used for deduplicated data for a (MSDP), MSDP Cloud, or an MSDP volume group (MVG). |

An disk type storage unit is used for a dedicated disk that is directly attached to a NetBackup media server. An selection is available only when the Data Protection Optimization Option is licensed. NetBackup assumes the exclusive ownership of the disk resources that comprise an AdvancedDisk disk pool. If the resources are shared with other users, NetBackup cannot manage disk pool capacity or storage lifecycle policies correctly. For AdvancedDisk, the NetBackup media servers function as both data movers and storage servers. | |

An disk type storage unit is used for disk storage, usually provided by a third-party vendor. The actual name of the disk type depends on the vendor. An OpenStorage selection is available only when the OpenStorage Disk Option is licensed. The storage provided by storage vendor partners is integrated into NetBackup via the API. The storage host is the storage server. The NetBackup media servers function as the data movers. The storage vendor's plug-in must be installed on each media server that functions as a data mover. The logon credentials to the storage server must be configured on each media server. | |
An disk type storage unit is used for backups to cloud object storage, with no deduplication. See the NetBackup for Cloud Object Store Administrator's Guide. | |

A type storage unit consists of a directory on a locally-attached disk or a network-attached disk that is exposed as a file system to a NetBackup media server. NetBackup stores backup data in the specified directory. Notes about the type storage unit:

Not all settings are available on each disk storage unit type.
Note:
It is recommended that you do not impose quotas on any file systems that NetBackup uses for disk storage units. Some NetBackup features may not work properly when file systems have quotas in place. (For example, the capacity-managed retention selection in storage lifecycle policies and staging to storage units.)
