Problem Description
Backup jobs may complete with a status of "Successful with Errors" if temporary files are open during the backup process.
These files typically have names beginning with the prefix
~$.Such files are usually Microsoft Office temporary files or system-generated temp files that are in use at the time of backup.
Cause
The backup agent is unable to process these temporary files because they are locked by the application. As a result, the files are skipped, and the job is marked as successful with errors.
Resolution
To prevent these errors, configure or edit a content rule to exclude temporary files from the backup.
To edit content rule for NAS backups, see: Manage Content Rules in NAS
To edit content rule for File Server backups (FS), see: Manage Content Rules
In the File Exclusions section of the content rule, add the following pattern:
*~*
This ensures that temporary files such as ~$filename.docx are excluded.
Verification
Run the next backup (scheduled or manual).
Review the Job Details in the Management Console.
Confirm that:
The job completes as Successful, without errors related to temporary files.
Files starting with
~$are excluded and do not appear in the processed file list.
If temp files still appear:
Double-check the exclusion rule syntax (
*~*).Ensure the correct content rule is applied to the intended backup set or NAS share.
Additional Information
Excluding temporary files does not affect data integrity, as these files are automatically recreated by applications such as Microsoft Office.
If errors persist for non-temp files, further troubleshooting is required.
