Xopero Desktop application is meant for installing on PCs with Microsoft Windows operating systems. It allows the PC user to create backup and synchronize data. Xopero works both as an application and as a service. The application provides only a graphical user interface, which can be used to configure the application and all settings reffering to backups. The service, works in the background and does not require user intervention; it is responsible for creating backups and synchronization of the Briefcase. Thanks to this solution, after creating backup sets and configuring the Briefcase there is no need to run the client application, whereas the service will work in the background and carry out entrusted operations; everything will become transparent for the user.
