The restore job uses High encryption settings for Data Domain communication. This issue is more likely to occur when restoring across a WAN link between the Windows client and the Data Domain system.
Resolution

In the restore job settings, set Encryption method from Data Domain system to None.
This disables SSL encryption for the restore operation. -
If disabling encryption is not permitted due to security policies:
- Open a case with Dell Support for further troubleshooting.
Additional Information
- Disabling encryption may expose data during transfer; confirm compliance with your organization’s security requirements.
- Issue primarily affects WAN-based restores; LAN restores may succeed with encryption enabled.
