Error Message

The backup job fails with error 0xe000fe30 - A communications failure has occurred.

 

Cause

The root cause of the issue could be the large size of the backup job if the backup job exceeds 10TB. This size limitation causes a communications failure between the Backup Exec server and the remote server. Additionally, the lack of successful job completion for the full job from the initial configuration indicates a recurring problem.

 

Resolution

To resolve the issue, follow these steps:

  1. Split the backup job into two separate jobs. If the job size is over 10TBs, splitting it into two smaller jobs will help overcome the communications failure. Divide the data into logical groups and create two or more separate backup jobs for each group.

  2. Update the backup job configuration: Modify the selection list for each backup job to include the appropriate data for each group. Ensure that all necessary files and directories are selected for backup.

  3. Add antivirus exclusions on the Backup Exec server: Initiate a debug on the server and add the recommended antivirus exclusions as mentioned in the provided tech note. This will prevent any interference from the antivirus software during the backup process.

  4. Test the backup jobs: After making the necessary changes, run the backup jobs and monitor their progress. Verify that the backup completes successfully without any communication failures.

  5. Verify data integrity: Perform a restore test to ensure that the backed-up data can be successfully restored. This step is crucial to ensure the reliability of the backup solution.
