Copying deduplicated data between deduplication storage folders or OpenStorage devices by using optimized duplication

Optimized duplication enables deduplicated data to be copied directly from one OpenStorage device to another OpenStorage device from the same vendor. Both devices must be attached to a single media server. If you have the Central Admin Server Option (CAS) installed, you can also copy data from one OpenStorage device on a media server to a different OpenStorage device on a different media server. With CASO, you can also copy deduplicated data from one deduplication storage folder on a media server to another deduplication storage folder on a different media server.

You set up a duplicate backup job to perform optimized duplication.

Step

For more information

If you are using CASO, do the following:

  • Verify that you have one central admin server option and at least one managed media server.

  • Verify that the media server from which you want to copy the deduplicated data has a deduplication storage folder (for client or media server deduplication) or an OpenStorage device (for appliance deduplication). Also verify that the media server to which you want to copy the deduplicated data has a deduplication storage folder (for client or media server deduplication) or an OpenStorage device (for appliance deduplication).

  • Verify that the media servers are enabled for sharing.

Note:

This information applies only to CASO. If you do not have CASO, skip this step.

See Sharing a deduplication device between multiple media servers.

Create a backup job that uses an OpenStorage device or a deduplication storage folder as the destination.

See Creating a backup job by setting job properties.

Create a duplicate backup job and select the appropriate OpenStorage device or deduplication storage folder as the destination.

Note:

The destination device for the duplicate job must be the same type of device from the same vendor as the device that was used in the source backup job.
