A Survey of Storage Remote Replication Software

Data availability at all times is the key requirement for major business operations and the financial impact of business outage could be disastrous (see table 1). There could be many majors threats to information availability, be it natural disasters, unplanned or planned occurrences. Remote replication is the process of creating copies of data known as replica at geographically distance location referred to as remote sites. With the advent of intelligent storage systems, there had been quite a pool of replication technologies emerging to avert business outage. In this paper we would describe important concepts of business continuity and remote replication mechanisms along with a study of major remote replication software available from major players in the storage technology.
