Excluding Files or Folders in Windows NT Backup – KB10391739


Description:  How to exclude files or folders in Windows NT Backup

Common customer description: My NT Backups are failing

Probing questions: When did this issue start?

Steps to isolate: Check the reports in Windows NT Backup

Steps to resolve:

1. Log into the backup server

2. Open the NT Backup console

3. Go to Tools>>Report


  • In this screen, it will show you all the backup jobs that has been done
  • To View the job, click on the selected date and press “View”

4. When you are viewing the job, figure out what the backup job has an issue with. Is it a file? Folder? Log File? Executable file? The Exchange database?



  • In this case, the backup is having an issue with a file called DominqueWEB.docx and the Microsoft Information Store

5. Once you figure out what the errors are, see if they are still even in the server. Follow the path, is the file still on the server? was it deleted? was it renamed?

For the Exchange issue, does the server have Exchange? Is the database mounted or dismounted? Did they migrate to a different email solution (office 365, Google Apps)?

6. Before you can exclude, click the Backup Tab

7. In this example the file was deleted, to exclude the file, follow these steps:

  • Go to Tools>>Options


  • Click the Exclude Files Tab

Exclude Tab

  • Click the “Add new…” button on the top middle (will say Files excluded for all users…)


  • In this part, make sure you know the file location that you need to go to. Click on “Browse…”


  • Browse the the location of the file


  • Now in order to add this file. NT Backup wants you to include a registered file type or file name. If you don’t you will get this error:


  • In this case the file is a .docx so in the custom file max put .docx


If it’s just a folder that needs to be excluded, in the custom file put * or *.*

  • When you are done, click OK. Then click Apply then OK again

8. Let the backup run according to the backup schedule unless you are able to run the backup job at that moment

9. Check on the backups again to see if it completed successfully. If it doesn’t, double check the logs again and make sure that there wasn’t any other errors reporting. If it’s the same issue, double check for other locations and double check to make sure the path is correct.

10. If it completes, watch it for a few days to make sure nothing else is wrong. If you had to bill them for anything, make sure when you close the ticket to put the ticket to “To Be Billed” instead of “Closed”

Additional considerations: If it still fails, you could also re-create the backup job.
