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

Backup Exec supports optimized duplication, which 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. For example, you can copy data from one Symantec PureDisk device to another Symantec PureDisk device. Because the data is deduplicated, only unique data is copied between the devices.

Note:

Optimized duplication is not available for backup sets that are enabled for Granular Recovery Technology.

If you use the Central Admin Server Option (CASO), the functionality of optimized duplication is expanded to let you do the following:

  • Copy data from a deduplication storage folder on one media server to a deduplication storage folder on another media server.

  • Copy data from an OpenStorage device that is attached to a media server to another OpenStorage device that is attached to a different media server.

To use optimized duplication with CASO, the following requirements must be met:

  • You must have a CASO license.

  • All media servers that you use with CASO as either a central administration server or as managed media servers must use the 64-bit version of Windows.

  • You must have a central administration server and at least one managed media server in your CASO environment.

  • For client deduplication and media server deduplication, you must configure one deduplication storage folder on the media server from which you want to copy the deduplicated data. You must also configure one deduplication storage folder on the media server to which you want to copy the deduplicated data.

  • For appliance deduplication, the media server from which you want to copy deduplicated data must have the appropriate plug-in for the OpenStorage device and a properly configured OpenStorage device. In addition, the media server to which you want to copy the deduplication data must have the appropriate plug-in for the OpenStorage device and a properly configured OpenStorage device.

    Note:

    The OpenStorage devices must be from the same vendor. You cannot copy deduplicated data between OpenStorage devices from different vendors.

  • You must share deduplication devices between the media servers.

  • You must inventory and catalog the media on the destination server before you recover any files from the duplicated backup set. You must do this regardless of how the catalog sharing option is configured for CASO.

Optimized duplication is available for OpenStorage devices from selected vendors. You can find a list of compatible devices at the following URL:

Hardware Compatibility List

To copy data between OpenStorage devices or deduplication storage folders, you must create a duplicate backup job. 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. You can restore data from either device.

See Sharing a deduplication device between multiple media servers.
