Types of destination volume integrity verification

You can run different types of SnapMirror destination volume integrity verifications for different SnapManager operations.

• Backup with verification
  When you run integrity verification on the SnapMirror destination volume, SnapManager requests SnapMirror updates using SnapDrive, verifies the backup, and monitors the SnapMirror update activity through SnapDrive.
• Integrity verification for test restore operations
  When you run an integrity verification for the test restore operation, SnapManager performs integrity verification and updates the verification results to the source SnapInfo volumes.
• Integrity verification for a restore process
  When you run an integrity verification for a restore process, SnapManager performs integrity verification, updates source SnapInfo volumes, and logs additional steps to event logs and restore reports.
• Remote destination volume integrity verification
  When you run integrity verification on a remote destination volume, SnapManager performs integrity verification and updates source SnapInfo volumes.
• Deferred integrity verification
  In deferred integrity verification, SnapManager checks if a backup copy exists and then updates SnapMirror if you select to update SnapMirror after the backup operation. If a backup Snapshot copy does not exist, SnapManager displays an appropriate error message.
