Problem description

By design, when the File server backup starts which has Pre/Postscript in the policy, it stays in Queued until the script execution gets completed.

This Queued condition can happen to Schedule as well as for Backup Now operation.

Make sure the Pre-Script location mentioned in the Policy and the actual location on the server is correct.

Edit the script and check the destination location of the script exists.

You should have enough space on the drive where output is pointed.

Try to run the script manually to validate if it runs.

If you get a Pop Window, once you run the script manually like “Windows server backup software” is not installed on Windows, then install the feature from Server Manager.
