Enabling Data Integrity Validation on Network

To verify the integrity of the data transferred over the network, Cyclic Redundancy Check (CRC) checksums are generated at the respective clients before the data transfer. These checksums are verified with the CRC checksums generated by the MediaAgent, as soon as the data transfer is complete, and vice versa. This verification is done for all backup and restore operation for all data travelling to and from the MediaAgents.


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