Business Required Disaster Recovery and Business Continuity
What is Disaster Recovery?
Is that so simple to describe? Yes, it is. Theoretically, DR is a concept of managing your backups, systems etc with a presumption of data can be used in case you have any failures/accidents/natural calamities where your existing system failed to deliver any services. DR Principles are similar to all industries, Goal is to keep systems and User Experiences live or get back online.
What is Business Continuity and How it differs from Disaster Recovery?
DR is all about technicalities. Like Backup, Replication, Failover, Failback. Business Continuity is second and most critical, how you gonna manage Disaster Recovery services. Make sure all users know how to handle application “back online” from Disaster. Can you imagine 2000 users waiting for your instructions to start normal work? According to studies, 30% business never came back after disaster just because they failed to bring back things fast. Consider a bank, millions of people access online services and one-minute downtime may take loss of 5% customers. Regular failover testing, Regular Business Continuity plan updates, Improving Employee Awareness on how to manage after DR etc. will help business to survive.
How to choose a DR Plan/Solution?
Before moving into technology. Make clear plans with decision makers/crisis managers to understand critical part of Data. Analyze below metrics.
a) How much downtime business can absorb?
b) How much Data they afford to lose?
c) Budget allocations and other impacts.
This can be converted to DR Terms.
a) RTO (Recovery Time Objective) – Maximum downtime affordable
b) RPO (Restore Point Objective) – Maximum amount of Data can be lost.
c) Based on Budget, Business can decide HOT/COLD DR
Business and IT Team needs to work together to understand all these metrics that is going to help your business grow further.
