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.
