The most critical and important aspect of disaster recovery is to protect the data from application fail over, natural disasters and infrastructure failures. Taking frequent backups of the huge volumes of data and storing it is also an integral part of the disaster recovery plan. Various scenarios of database replication strategies and techniques are provided in this survey paper addressing the need for replication of data. A wide range of open source and commercial tools have evolved over a period of time to deal with the issues and challenges involved during the process of database replication. This paper describes the general characteristics of replication & disaster recovery. Later the features of open source and commercial replication tools are compared.
