Configuring global deduplication using the Veritas Data Deduplication storage server across the domain
Access Appliance supports the configuration of multiple Logical Storage Units (LSU) with Veritas Data Deduplication. Using the global deduplication feature, multiple NetBackup domains can access the Veritas Data Deduplication storage server in Access Appliance. By default, only one NetBackup domain is preconfigured with the Veritas Data Deduplication storage server. To configure multiple domains, you need to create a new user for each domain. Different NetBackup domains require a different Veritas Data Deduplication user. A specific user can access data only from the domain to which the user has been added.
To add a new user to the deduplication storage server, enter the following:
dedupe> adduser username
Where username is the user name of the second domain user.
The command should be run on the Access Appliance cluster.
After a new user name is added to the storage server in Access Appliance, you can use the credentials of the new user to add a STU on NetBackup in the new domain. Any backups taken from the new domain are visible only to the new user. The NetBackup domain can access the catalog and data of the user. When you configure Auto Image Replication and add the storage target, use the Veritas Data Deduplication user name used by the target NetBackup domain.
To show the list of users of the deduplication storage server, enter the following:
dedupe> listuser
The command should be run on the Access Appliance cluster.
Note:
You must use the deduplication IP address of Veritas Data Deduplication host that was previously configured with the first domain in the form when you provide the details of the storage server.
