The Media Password is used when recovering data through Media Explorer or when the 'Catalog Media' option for tape is used. A media password is essential when using:
Hardware encryption
Commvault® software copy-based encryption (with the 'Direct Media Access' option set to 'Via Media Password')
By default, the password is set for the entire CommCell® environment in the System applet in Control Panel. The default password is blank. Storage policy level media passwords can be set, which will override the CommCell password settings. For higher level of security or if a department requires specific passwords, use the 'Policy level' password setting which is configured in the Advanced tab of the storage policy properties.
