About the AdvancedDisk storage option
The NetBackup AdvancedDisk storage option lets you use the disk storage that is exposed to NetBackup as a file system for backups. Storage can be direct attached storage (DAS), network attached storage (NAS), or storage area network (SAN) storage.
NetBackup requires exclusive access to the storage for capacity management and load balancing.

Easy to deploy and use
NetBackup discovers the storage and uses NetBackup storage units and backup policies to use the storage.
Lets you increase storage unit capacity by adding disks. Only add the capacity required, then update the NetBackup disk pools. Logical units of storage span physical boundaries, so you do not have to create new NetBackup storage units or change the backup policies.
Multiple storage units can share a disk pool. Space is allocated dynamically as required. Automatic space allocation reduces the risk of backup failure.
Best fit selection
NetBackup predicts the size of the backup and selects the storage on which the backup fits best. The goal is to avoid out-of-space conditions and disk spanning.
Load balancing can occur at two levels, as follows:
Intelligent capacity management
NetBackup expires backup images when the storage that is consumed reaches a threshold. The disk pool high water mark applies to both individual disk volumes and to disk pools.
You can classify data based on its importance and manage it differently throughout each stage of its life. After it has been duplicated, data can be selectively expired based on the relative importance to the business. you can ensure that important backups are available for rapid restore for longer periods, ensuring your recovery time objectives.
