# Copy Data Management

Copy data management helps you administer active copies of production data. It reduces the amount of primary storage needed and the time taken for making copies. A single copy of production data is captured and used for all copy provisioning purposes. It continuously captures incremental change data from the production database, running in forever-incremental mode to make backup operations faster. A self-service console makes it easy to provide secure copies.

You can use the same backup for copy data management, backup, and recovery operations, including the following:

- Creating development or test copies

- Performing in-place partial restores

- Performing out-of-place restores for disaster recovery

- Performing disaster recovery operations

Commvault Copy Data Management uses the following methods, based on the available storage capabilities:

- Array snapshot technology, making snapshot copies from primary storage using the hardware and software capabilities of the array.

- Snapshot copies made from secondary storage, such as a company's own storage or any supported secondary storage option. This solution is agnostic to the type of secondary storage that is used.
