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.

Table: Disk media descriptions

Type of disk storage unit	Description
AdvancedDisk	An AdvancedDisk disk type storage unit is used for a dedicated disk that is directly attached to a NetBackup media server. An AdvancedDisk 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. See the NetBackup AdvancedDisk Storage Solutions Guide.
BasicDisk	A BasicDisk 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 BasicDisk type storage unit: Do not include the same volume or file system in multiple BasicDisk storage units. BasicDisk storage units cannot be used in a storage lifecycle policy.
Cloud Storage	A Cloud Storage disk type storage unit is used for storage in a cloud, usually provided by a third-party vendor. The actual name of the disk type depends on the cloud storage vendor. A Cloud Storage selection is available only when the Data Protection Optimization Option is licensed. The storage is integrated into NetBackup through an API. The cloud storage vendor partners with Veritas to integrate the storage into NetBackup. A vendor host on the Internet is the storage server. The NetBackup media servers function as the data movers. See the NetBackup Cloud Administrator's Guide: See the NetBackup Cloud Administrator's Guide.
OpenStorage	An OpenStorage 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 is integrated into NetBackup through an API. The storage vendor partners with Veritas to integrate the storage into NetBackup. 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. See the NetBackup OpenStorage Solutions Guide for Disk.
PureDisk	A PureDisk disk type storage unit is used for deduplicated data for a Media Server Deduplication Pool. PureDisk appears as a selection when the NetBackup Data Protection Optimization Option is licensed.

Not all settings are available on each disk storage unit type.

Note:

Veritas recommends 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.)
