Configuring Veritas Data Deduplication with WORM

You can configure Veritas Data Deduplication with WORM using both the Access Appliance GUI and command-line interface. Veritas recommends that you configure Veritas Data Deduplication usng the GUI as it ensures that the configuration is performed with the appropriate filesystem size, and volume layout along with catalog filesystem creation.

You can configure Veritas Data Deduplication with WORM when the lockdown mode is Enterprise or Compliance.

For more information, see the About lockdown modes section in the Access Appliance Administrator's Guide.

Only a single Veritas Data Deduplication pool is supported on Access Appliance. Veritas does not support converting an existing Veritas Data Deduplication pool (without WORM) to a Veritas Data Deduplication pool with WORM.

If you want to use the same appliance to configure a Veritas Data Deduplication pool with WORM, you must do the following:

You cannot convert non-WORM images to WORM images directly. But it is possible to convert the images using other methods. For example, you can provision an MSDP-C instance using Access appliance if there is enough space to store a copy of the data present in Veritas Data Deduplication. You can also provision another Access Appliance with Veritas Data Deduplication and duplicate all images onto it. After duplicating the images to another storage unit, you can expire the images from Veritas Data Deduplication and unconfigure it. Then, you can proceed to configure Veritas Data Deduplication in WORM mode and duplicate the data back to the Access Appliance with WORM protection. After the configuration, the server is WORM-enabled but the existing images are not WORM-enabled.
