The NetBackup model for disk storage accommodates all Enterprise Disk Options. That is, it is the model for all disk types except for the Basic Disk type.
The following items describe components of the disk storage model:
An entity that moves data between the primary storage (the NetBackup client) and the storage server. NetBackup media servers function as data movers.
Depending on the Enterprise Disk Option, a NetBackup media server also may function as a storage server.
An entity that writes data to and reads data from the disk storage. A storage server is the entity that has a mount on the file system on the storage.
A collection of disk volumes that are administered as an entity. NetBackup aggregates the disk volumes into pools of storage (a disk pool) you can use for backups.
A disk pool is a storage type in NetBackup. When you create a storage unit, you select the disk type and then you select a specific disk pool.
