Commvault supports data backups on high capacity, low cost, and long term storage disk devices, also known as the cold storage devices. These cold storage devices are beneficial for storing dormant data which is not necessarily accessed regularly by organizations but might still be of use.
Example
Spectra Logic Verde DPE (Digital Preservation for Enterprise). You can use Spectra Logic Verde DPE as a disk target and set up long term retention for extended time period.
