# Adding an Additional Deduplication Partition For Commvault Grid

A second location for backup data can be created on Cloud or Disk Storage remote to Commvault Grid. This requires the creation of a secondary Deduplication DataBase (DDB) to ensure that the data is retained in reduced format. This configuration is referred to as Deduplication Extended Mode.

## Procedure

1. Create a disk or cloud storage library as the storage target for the off-site copy. For more information about creating the storage, see one of the following:

   - Creating a Disk Library

   - Creating a Cloud Storage Library

2. Create a storage pool using the storage library. For more information about creating a storage pool, see one of the following:

   - Configuring Disk Storage Pool

   - Configuring Cloud Storage Pool

     Important

     - Use the Partition Path /ws/ddb for the Deduplication Database

     - Do NOT re-partition /ws/ddb to create additional drives to host DDBs.
