You create a scheduled backup in Windows Server 2003/2008/2012/2016 for regular data backup, but Windows Server Backup schedule not running on schedule as expected. When you manually start the backup, it runs as successfully. This article will show you how to troubleshoot and fix the Windows Server 2008/2012/2016 scheduled backup not working problem.

Causes for Windows Server Backup schedule not running

Many reasons could result in Windows backup schedule not working.

  • Scheduled backup will fail when the target backup location is not available to write data to at the scheduled time.

  • That the Volume Shadow Services and other related services are neither set to Automatic nor Started will also lead to scheduled backup unable to start.

  • If you use Task Scheduler to run Windows Server Backup, the Task Scheduler service or settings may be the cause of Windows Server Backup not running on schedule error.

Solutions to Windows Server Backup not running on schedule

Based on the above causes, you can check the methods below to fix the Windows Server 2003/2008/2012/2016 backup schedule not running problem.

1. Whether you want to backup to external hard drive or network share, make sure the destination location is well connected and you do have permission to write data to it.

2. Type “services.msc” in the Run box and press Enter to open Services. Then locate the Windows Server Backup service and Volume Shadow Services, and change the Startup type to Automatic.

3. If after that, schedule backup is not started as it should, you can write a wbadmin backup command or make a script batch file and then let Task Scheduler run it.

4. For those who are using Task Scheduler to run scheduled backup and it still fails, you can manually start the task to see if it works. If it backups successfully, you can check if the Task Scheduler service is set to Automatic and the task was set to Run whether user is logged on or not. If it fails after a manual start, you need to check if the wbadmin command is correct.
