Overview
A traditional backup process is based on the direct communication between the backup application (application, which initiates and performs backup) and an application to be backed up. This backup method requires from the backup application an individual interface for each application it backs up.
The number of applications on the market is constantly increasing. The necessity of handling application specific features can cause difficulties in backup, restore, and storage activities. An effective solution to this problem is introducing a coordinator among the actors of the backup and restore process.
