# Supported Cloud Storage Features

All the storage related features available in the Commvault software are supported for Cloud Storage.

However, the following exceptions should be noted.

Feature | Notes
--- | ---
Life Cycle Policies | You can use life cycle policies to move data between tiers, but it is not recommended when archive storage class is selected. Commvault software will copy metadata on warmer tiers and data on archive tiers. Do not apply life cycle policies or use external tools to delete data from the storage used by Commvault for backups. The Commvault software automatically manages data life cycle and deletes backup data according to the defined retention policy. Note For WORM-enabled storage, you can configure a life cycle policy to delete object versions. This policy is supported only for version clean-up operations on WORM-enabled storage.
Auxiliary Copy and Synthetic Full backup operations in Archive Cloud Storage products | Archive Cloud Storage products as the source for Auxiliary Copy, Synthetic Full backups, Data Verification and Content Indexing operations, is not supported. This is because the data may be archived off and these operations are performed on low latency media. To perform these operations in Archive Cloud Storage products, first restore the data to the main cloud storage location. When all of the required backup data is restored to the main cloud storage location, perform an Auxiliary Copy, Synthetic Full backup, Data Verification and/or Content Indexing operation on the data.
Deduplication Database (DDB) reconstruction | DDB reconstruction is not supported by the Cloud Storage Archive Recall workflow. For more information on reconstructing a DDB, see Deduplication Database Recovery.
