Configuring media server deduplication in NetBackup

Table: MSDP configuration tasks describes the configuration tasks.

The NetBackup Administrator's Guide, Volume I describes how to configure a base NetBackup environment.

Table: MSDP configuration tasks

Task	Procedure
Configure a deduplication storage server	How many storage servers you configure depends on: your storage requirements and on whether or not you use optimized duplication or replication. When you configure a storage server, the wizard also lets you configure a disk pool and a storage unit. See About MSDP storage servers. See MSDP storage path properties. See About MSDP optimized duplication and replication. Which type of storage server to configure depends on the storage destination. See About the NetBackup deduplication destination. See Configuring a storage server for a Media Server Deduplication Pool.
Configure a disk pool	If you already configured a disk pool when you configured the storage server, you can skip this step. How many disk pools you configure depends on: your storage requirements and on whether or not you use optimized duplication or replication. See About disk pools for NetBackup deduplication. See Configuring a disk pool for deduplication.
Configure a storage unit	See Configuring a Media Server Deduplication Pool storage unit.
Configure a backup policy	Use the deduplication storage unit as the destination for the backup policy. If you configured replication, use the storage lifecycle policy as the storage destination. See About MSDP backup policy configuration. See Creating a backup policy.
Configure optimized duplication copy	Optimized duplication is optional.
Configure replication	Replication is optional.
Configure MSDP client-side deduplication	See Configuring MSDP client-side deduplication.
Create NetBackup log file directories on the primary server and the media servers	See NetBackup MSDP log files. See Creating NetBackup log file directories for MSDP.
Configure the Deduplication Multi-Threaded Agent behavior	The Deduplication Multi-Threaded Agent uses the default configuration values that control its behavior. You can change those values if you want to do so. See About the MSDP Deduplication Multi-Threaded Agent. See Configuring the Deduplication Multi-Threaded Agent behavior. See Configuring deduplication plug-in interaction with the Multi-Threaded Agent.
Configure the fingerprint cache behavior	Configuring the fingerprint cache behavior is optional. See About the MSDP fingerprint cache. See Configuring the MSDP fingerprint cache behavior.
Enable support for 400 TB MSDP	Before you configure a storage server that hosts a 400 TB Media Server Deduplication Pool, you must enable support for that size storage. See Enabling 400 TB support for MSDP.
Create the data directories for 400 TB support	For a 400 TB Media Server Deduplication Pool, you must create the data directories under the mount points for the storage directories. See Creating the data directories for 400 TB MSDP support.
Add the other volumes for 400 TB support	For a 400 TB Media Server Deduplication Pool, you must add the second and third volumes to the disk pool. See Adding volumes to a 400 TB Media Server Deduplication Pool.
Enable encryption	Encryption is optional. See Configuring encryption for MSDP local storage volume.
Configure optimized synthetic backups	Optimized synthetic backups are optional. See Configuring optimized synthetic backups for MSDP.
Configure MSDP restore behavior	Optionally, you can configure NetBackup to bypass media servers during restores. See How MSDP restores work. See Configuring MSDP restores directly to a client.
Specify advanced deduplication settings	Advanced settings are optional. See About the MSDP pd.conf configuration file. See Editing the MSDP pd.conf file. See MSDP pd.conf file parameters.
Protect the MSDP data and catalog	See About protecting the MSDP data. See About protecting the MSDP catalog.
