You can associate one or more Backup Gateways to a disk storage.

A Backup Gateway can have one or both of the following roles:

• Storage: The Backup Gateway with this role manages the backup data.
• DDB: The Backup Gateway hosts the deduplication database. The software automatically selects the Backup Gateways to host the DDBs for optimal usage. The software hosts the new DDBs on the Backup Gateways when the software adds more deduplication databases (DDBs) for horizontal scaling or when a DDB is sealed and a new DDB is created.

Before You Begin

• User must have edit permission on the storage pool.
• User must have Library Administration or Library Management permission on the storage pool to perform the following operations:
  • Add or remove Storage role
  • Add or remove both Storage and DDB roles
