Data recovery assistance required in today's world for producing information in huge sum. Regardless of systems are down, the cloud service providers provide security to the client. A lot of client's private information is stored in cloud environment. The needs for recovery of data services are growing and an efficient powerful data Rescue methods to be developed in case of information lost In a disaster. The inclination behind recovery strategy is to collect information from alternate server

Situations like Fire, Natural calamities or any accidental deletion of data cannot be accessed once more. The scope of this recovery is to focus on enormous data recovery procedures that are used as a part of Cloud computing area. In addition, Identifying open issues and recovery stages are described. Recovery Point Objective: The period taken to recover the information after a disaster happens is classed as RPO. The requirement of this RPO is that Correlated Failures: If a disaster is occurred in an area which leads to high interruption of services, many customers approaches CSP to recover the data. The main task in instance is to allocate clients between servers in such a way that they can reduce correlated failure risk
