This technology helps in avoiding disruption during business activities and helps in data recovery and the continuity of business . In the early days , large companies who could afford to purchase that kind of technology were only using data replication . Today , there are many data replication tools that are

There are two major data replication technologies and they include the snapshots and remote replication . In snapshot replication , the replication is made through a copying by either snap-copy or pointer-based snapshots . The remote replication technology is used to replicate data on either another disk or in remote location and the copy can be made through synchronous or asynchronous replication methods (Nquyen , 1999

Before choosing any replication method , several elements have to be considered . First and foremost , one should consider cross-platform support which means that you should be sure if you want a database replication method that is limited to a particular vendors database .or does it allow cross-platform replication ' that is replication across different vendor databases (Nquyen , 1999 . Another factor to consider is the replication speed and efficiency of the replication technology . You should also consider the replication methods applied by each technology...
