Windows Home Server Not Starting Automatic Backups

Posted by jcnnghm Wed, 23 Feb 2011 08:57:00 GMT

I began experiencing an issue where Windows Home Server was not initiating automatic backups of my Windows 7 Ultimate 64-bit Desktop. I believe that the issues were related to a UPS that was incorrectly reporting that the system was on battery power 100% of the time, even if the system was actually on utility power. To work around the problem, I setup a task in the Task Scheduler to manually initiate an automatic backup. The command to initiate a backup is:

"C:\Program Files\Windows Home Server\BackupEngine.exe" -a

You’ll need to launch the command from an elevated command prompt to get it to work. You can schedule it by opening the Task Scheduler, selecting “Create Basic task”, then following the prompts until you get to Program/Script. Here you enter “C:\Program Files\Windows Home Server\BackupEngine.exe” as the program, and -a as the arguments. Once you complete the remainder of the wizard, the properties for the task will open. From here, make sure “Run with highest privileges” is checked on the General Tab, and “Start the task only if the computer is on AC Power” is unchecked on the Conditions tab. You many also want to check “Run task as soon as possible after a scheduled start is missed” on the settings tab, which will ensure the task runs as soon as it can if there is a missed time.

This process will create a manual task that will initiate WHS automatic backups every day.
