Disaster Recovery Site Planning

Implement the systems or capabilities required to deliver the plan.

 This will involve definition of some type of disaster recovery site to deal with situations where the data center or main facility are unavailable
 Primary types of sites include:

 HOT SITE
 Site that has live communication links, working systems and real data (typically with real-time data replication),ready for an Immediate or near-immediate fail over of operations

 WARM SITE
 Site that typically has live communication links and some amount or hardware, but typically requires Installation or software and/or restoration of data from tape or another media format

 COLD SITE
 Typically Is a facility where your staff can go to when a disaster Is declared,and which may have external communications, but which does not typically have pre-existing hardware, software or data

Hot Site Data Replication

 There are several ways to implement data replication in a Hot Site scenario,ranging from t1med copying of files or database backups to using replication software.
 It is important to account for the bandwidth requirements for the data being copied from site to site.
 Data replication can consume significant bandwidth, and therefore it Is important to plan this and ensure that disaster recovery replication does not consume precious Internet access bandwidth or WAN links and compete with existing applications.
 Make sure to account for the timing of replication.
