Off-host backup overview
One of the principal goals of NetBackup is to move I/O processing off the primary NetBackup client to a backup agent.
Table: Type of backup agents describes the types of backup agents.
Table: Type of backup agents
Type of backup agent | Description |
---|---|
A secondary or an alternate client performs the backup on behalf of the primary client. Compared to the other off-host methods, this approach reduces the backup I/O burden on the primary client to the greatest extent. | |
A NetBackup media server reads raw data from the client snapshot and writes it to a storage device, using mapping information that the client provides. | |
An NDMP (NAS) host performs the snapshot-only backup for Instant Recovery only. | |
Use to replicate NDMP snapshots. Select this agent in a policy that uses NDMP with Replication Director. For more information about configuring a policy to use NDMP with Replication Director, see the NetBackup Replication Director Solutions Guide. | |
Virtual machine host | A VMware backup host performs backups on behalf of the virtual machines. The host can also be configured as a NetBackup master or media server. |
