In Microsoft SQL Server 2012 or SQL Server 2014, you try back up a large database by using the Backup-SqlDatabase cmdlet, or you try to restore a large database by using the Restore-SqlDatabase cmdlet. In this situation, a time-out error occurs after 10 minutes. Additionally, you receive the following error message in Windows PowerShell:

Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.


The issue occurs because the Backup-SqlDatabase and Restore-SqlDatabase cmdlets use 600 seconds as the default time-out value.

Each new cumulative update for SQL Server contains all the hotfixes and all the security fixes that were included with the previous cumulative update. Check out the latest cumulative updates for SQL Server:


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
