Abstract

The present invention provides a system and method for management of Recovery Point Objectives (RPO) of a business continuity or disaster recovery solution. The system comprises a management server logically coupled with at least a first computer, at least a second computer, and a network coupling the first and the second computers. The first and second computers host at least one continuously available application and at least one data protection scheme for replicating the application data; the application data being periodically replicated from the first computer to at least the second computer. The system manages RPO by inputting an RPO value for the solution, calculating a real time RPO value for the solution, and making the real time RPO value equal to the input RPO value.
