About the storage lifecycle policies required for Auto Image Replication

To replicate images from one NetBackup domain to another NetBackup domain requires two storage lifecycle policies. The following table describes the policies and their requirements:

Table: SLP requirements for Auto Image Replication

Domain	Storage lifecycle policy requirements
Domain 1 (Source domain)	The Auto Image Replication SLP in the source domain must meet the following criteria: The first operation must be a Backup operation to a Media Server Deduplication Pool. Indicate the exact storage unit from the drop-down list. Do not select Any Available. Note: The target domain must contain the same type of storage to import the image. At least one operation must be a Replication operation to a Media Server Deduplication Pool in another NetBackup domain. You can configure multiple Replication operations in an Auto Image Replication SLP. The Replication operation settings determine whether the backup is replicated to all replication targets in all master server domains or only to specific replication targets. See About trusted master servers for Auto Image Replication. The SLP must be of the same data classification as the Import SLP in Domain 2.
Domain 2 (Target domain)	If replicating to all targets in all domains, in each domain NetBackup automatically creates an Import SLP that meets all the necessary criteria. Note: If replicating to specific targets, you must create the Import SLP before creating the Auto Image Replication SLP in the originating domain. The Import SLP must meet the following criteria: The first operation in the SLP must be an Import operation. NetBackup must support the Destination storage as a target for replication from the source storage. Indicate the exact storage unit from the drop-down list. Do not select Any Available. The SLP must contain at least one operation that has the Target retention specified. The SLP must be of the same data classification as the SLP in Domain 1. Matching the data classification keeps a consistent meaning to the classification and facilitates global reporting by data classification. See the following topic for more information about Replication operation configuration:

Storage lifecycle policy requirements

Domain 1

(Source domain)

The Auto Image Replication SLP in the source domain must meet the following criteria:

The first operation must be a Backup operation to a Media Server Deduplication Pool.
Indicate the exact storage unit from the drop-down list. Do not select Any Available.
Note:
The target domain must contain the same type of storage to import the image.
At least one operation must be a Replication operation to a Media Server Deduplication Pool in another NetBackup domain.
You can configure multiple Replication operations in an Auto Image Replication SLP. The Replication operation settings determine whether the backup is replicated to all replication targets in all master server domains or only to specific replication targets.
See About trusted master servers for Auto Image Replication.
The SLP must be of the same data classification as the Import SLP in Domain 2.

Domain 2

(Target domain)

If replicating to all targets in all domains, in each domain NetBackup automatically creates an Import SLP that meets all the necessary criteria.

Note:

If replicating to specific targets, you must create the Import SLP before creating the Auto Image Replication SLP in the originating domain.

The Import SLP must meet the following criteria:

The first operation in the SLP must be an Import operation. NetBackup must support the Destination storage as a target for replication from the source storage.
Indicate the exact storage unit from the drop-down list. Do not select Any Available.
The SLP must contain at least one operation that has the Target retention specified.
The SLP must be of the same data classification as the SLP in Domain 1. Matching the data classification keeps a consistent meaning to the classification and facilitates global reporting by data classification.

See the following topic for more information about Replication operation configuration:

Figure: Storage lifecycle policy pair required for Auto Image Replication shows how the SLP in the target domain is set up to replicate the images from the originating master server domain.

Note:

Restart nbstserv after you make changes to the underlying storage for any operation in an SLP.
