Article ID: MM0049 Auxiliary Copy or Restore job fails when encountering invalid or unreadable data on the disk,

Symptom

Auxiliary Copy job or restore job fails with the following error message:

Error Code 62:1421 Data Integrity validation failed for the data read from media

Cause

 Job has encountered invalid or unreadable data on the disk.

Resolution

  1. Run the data verification job to view the jobs that have the invalid data for a storage policy copy.

    See Data Verification for instructions.

    If you have service pack 7 or higher installed, run deduplicated data verification job to view the jobs that have the invalid data for a storage policy copy.

    See Verifying Deduplicated Data for instructions.

    When the data verification job is complete, the backup jobs with invalid data are identified with data verification status as Failed.
  2. Run the backup job.

    For more information on how to run backups, see the documentation for the specific agent.

    When the backup job is run, the new data blocks are not referred to the invalid data. As a result, new baseline data is written to the storage media.
