What is a service?
Windows services, formerly known as NT services, enable you to create long-running executable applications that run in their own Windows sessions. Windows services can be configured to start when the operating system is booted and run in the background as long as Windows is running, or they can be started manually when required. These services can be automatically started when the computer boots, can be stopped and restarted, and do not show any user interface. These features make services ideal for use on a server or whenever you need long-running functionality that does not interfere with other users who are working on the same computer. You can also run services in the security context of a specific user account that is different from the logged-on user or the default computer account.
After installing and starting the service, you DO NOT need to log in Windows and start up the software for backing up and restoring, all of the waiting tasks will run on schedule in the background without any users logged in.
You can start and stop the service any time in the software, and execute all of operations on the tasks ( create, edit, remove, copy, view logs, start, stop, run, etc. ) if the service is started or not.
