This paper discusses about the Continuous Data Protection (CDP) which is an emerging technology that offers faster data restoration and more certain data protection than traditional Backup and Recovery (B/R) technologies. Traditional backup and recovery using magnetic tape technology generally is limited to a recovery time of 24 hours: If a failure occurs today, the most recent data available to restore was yesterday's. Thus, any data added or changed since yesterday will be lost. This would be referred to as a "24-hour Recovery Point Objective (RPO)." Therefore, up to 24 hours of data can be at risk. Data-replication methodologies have emerged to reduce the 24-hour loss window of risk associated with tape backup.
