You can check the status of your Viper Scheduled Backup by looking at Windows Scheduled tasks. This is the repository of all scheduled tasks on a computer.
1) How to see Scheduled Tasks in Windows XP
You can get to the Windows Scheduled Tasks in Windows XP by navigating to Start -> Program Files -> Accessories -> System Tools -> Scheduled Tasks.
2) In Windows Vista & Windows 7
Click on Start/ Search --> Type Task Scheduler ---> You will see it appear, and can run from there. (You can also go to Progams/Accessories/System Tools/ Task Scheduler)
If you have correctly scheduled a backup with Viper Online Backup, there will be an icon with the Viper Online Backup logo sitting there. Right click and view properties.
