I have created automatic backups of my data using the built-in automatic backup feature of Vista Professional.
However, the automatic backup refuses to run if I am running on battery.
How can I enable this job to run even when battery powered?
I'm answering my own question here since I found the solution and wanted to share it :)
The automatic backup is scheduled using the regular Windows Task Scheduler, and advanced parameters can be changed there.
Other options can also be changed here. Note that I haven't tested whether changing the automatic backup using Backup Status and Configuration overwrites these changes.
Note: Although this permits the job to run on battery, it still failed when I tried to start the job manually. To manually start the job you need to go through the "Schedule tasks" tool and run the job from there.
