Enabling Cross-Region Copy of an Amazon Redshift Snapshot

You can enable cross-region snapshot copy operations for an Amazon Redshift cluster group.

Before You Begin

To specify the permissions to Amazon Web Services (AWS) resources that Commvault requires to perform cross-region copies of Redshift snapshots, download the amazon_redshift_backup_restore_permissions.json file and use it on the AWS command line.
To enable the mappings for the plan, create a server plan that is assigned to the cluster group, specifying the addition of a vault/replica snapshot copy to the plan. Specify Amazon as the vendor for the snapshot mappings. For more information about adding a snapshot copy, see Adding a Snapshot Copy to a Plan.
If the Redshift cluster is KMS encrypted, do the following:
- Identify the KMS key in the destination region for encryption.
- Add cvlt-redshift as a tag to the KMS key in the destination region and set the value to empty.

From the navigation pane, go to Protect > Databases.

The Instances page appears.
Click the instance.

The instance page appears.
In the Cluster groups section, click the cluster group.

The Snapshot properties appear.

The region mapping information initially displayed is inherited from the plan.
Modify the region mapping:
1. In the row for the mapping, click the action button , and then select Edit.
  
  An edit regions dialog appears.
2. From the Destination region list, select a region.
3. Click OK.
You can map only one destination region to each configured source region per instance group.
To create more region mappings, do the following:
1. In the Snapshot section, click Add.
  
  The Add a region mapping dialog box appears.
2. From the Source region list, select a source Amazon Web Services region.
3. From the Destination region list, select a target Amazon Web Services region.
Click OK.

The next backup applies your changes and enables cross-region snapshot copy operations.
