Disaster recovery is not what it used to be.

In the event of a flood or fire, for example, organisations have restored tape-based backup data from a remote location. This option is becoming less realistic as time constraints, data volumes and the cost of being offline continue to grow. Another option is data replication, but this carries its own challenges.

The result is what might be termed a replication gap, in which disaster recovery needs are moving beyond many organisations’ technical and budgetary capabilities.
