Enabling Data Integrity Validation on Media

When data integrity validation on media is enabled, the CRC (Cyclic Redundancy Check) checksums are computed when data blocks are read from the source (client) and stored as part of backup. Subsequently, these checksums are used to validate data during Data Verification, Auxiliary Copy and Restore operations.


  1. From the CommCell Browser, expand Storage Resources > MediaAgent.
  2. Right click the appropriate MediaAgent, and then click Properties.
  3. In the MediaAgent Properties dialog box, on the General tab, select the Validation on Media checkbox, and then click OK.

    Default: Enabled.


When backup or auxiliary copy jobs are run to the storage policy associated with the MediaAgent, you can view the data integrity validation status under the CRC Checked column in the Jobs for Storage Policy Copy window. For instructions on how to view the job, see View the Jobs Associated with the Copy.
