Symptoms

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:

Note

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

Cause

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