Enabling Data Integrity Validation
Handling Data Integrity Validation Errors
Data Integrity Validation allows you to verify the integrity of the data secured by the data protection operations. Data Integrity Validation can be employed to verify the integrity of the data stored in the media, as well as the data transferred over the network.
Data Integrity Validation on Media checks the data restored from the media for any possible data corruption when the data resided in the media. The MediaAgent generates the integrity validation on data during the backup operation, and this is verified with the Data Integrity Validation generated on the data during the restore operation. Note that this option must be enabled during the backup as well as the restore operations.
To verify the integrity of the data transferred over the network, the Data Integrity Validation generated at the respective clients before the data transfer will be verified with the Data Integrity Validation generated at the MediaAgent after the data transfer is complete, and vice versa. This option can be enabled during backup operations, restore operations, or both.
Data Integrity Validation is enabled at the MediaAgent. This option is disabled by default. Use the following procedures to enable/disable Data Integrity Validation:
If the Data Integrity Validation fails, the data protection jobs will be moved to a pending state with the corresponding error code and description mentioned in the Reason for Delay field of the job, displayed in the Job Controller. See Job Errors for more information.
The pending jobs can be handled as follows:
The This feature is supported on all platforms supported by MediaAgent. See System Requirements - MediaAgent platforms supported by MediaAgent.
Consider the following for mixed mode configurations:
The Jobs in Storage Policy Copies Report provides a list of data protection jobs associated with the storage policy copies based on the selected filter criteria. If the Data Integrity Validation for data is enabled for a job, that information is displayed in the Job ID status.
The Data Integrity Validation status is also displayed in the Jobs for Storage Policy Copy window when you view the Jobs of a Storage Policy Copy.
