Do You Mirror Your Data Remotely?

December 2004
Storage Magazine;Dec2004, Vol. 3 Issue 10, p16
This article presents the results of a 2004 survey of the use of remote data replication. Over the next couple of years, more than 63 percent of respondents that do not already replicate remotely plan to start. The lion's share of data is replicated between 11 kilometers and 1,000 kilometers from the primary site; however, a significant number of respondents replicate to a site less than 10 kilometers away, while 21.8 percent replicate more than 1,000 kilometers away. Array and host-based replication are the most popular techniques, but nearly one-fifth of respondents are also trying out fabric-based replication services.
