Backup job fails with a communications failure when selecting NIC and IPv4 with Direct Access

Problem

Backup job fails with a communications failure when all of the following conditions are met.

• Enabled the remote computer to directly access the storage device and to perform client-side deduplication
• Enabled Granular Recovery Technology (GRT) (Hyper-V backups with or without GRT)
• A Network interface is selected and IPv4 is additionally selected in either Protocol or Subnet.

Error Message

Final error: 0xe000fe30 - A communications failure has occurred.
Final error category: Server Errors

For additional information regarding this error refer to link V-79-57344-65072

Solution

Do not select IPv4 in the property of a backup job which uses the client-side deduplication.

Please note that the specified network Interface in the property of a backup job is effective for the Network Data Management Protocol (NDMP) which is used between Backup Exec Job Engine and Remote Agent. The network is not effective for the direct access between Backup Exec Remote Agent and the deduplication storage device. Please use hosts file to select a network interface for the direct access.

Backup Exec Deduplication option

Any Backup Exec Agents with GRT except VMware Agent.

Note: Because VMware Agent works on the Backup Exec server, the direct access and client-side deduplication would not work.
