Disaster Recovery

What is Disaster Recovery?

Disaster Recovery (DR) and Business Continuity are terms used to describe the methods used to mitigate against unexpected occurrences. Many businesses think that it will never happen to them, but what if it did? What if there was a massive power surge in your office which led to the data on your services becoming corrupt or what if the office became flooded or there was a fire? There are any number of situations which could potentially cost your business money in lost productivity or lost data if you haven't prepared for the worst. A number of organisations have gone out of business because they didn't put contingency plans in place before they suffered a catastrophic data loss. Think of DR as insurance policy.

Contingency and business continuity planning are of fundamental importance to the health of an organisation. It adds a layer of resilience, just in case.

Disaster recovery systems most commonly refer to a second set of computer systems that are physically located away from your main datacentre or place of work. These secondary systems are kept constantly up to date by means of various technologies that replicate continuously with the live production systems.

Which Systems Should I Protect?

All of them! If possible. Start with what your organisation considers to be most critically important components of your IT infrastructure and work your way down. Some technologies have resilience built into them by default, for example if you have multiple Active Directory domain controllers in different physical locations, you've already protected your directory services as the domain controllers are constantly replicating with each other and so are protected in case of disaster.

These days most database, file and email systems have some form of replication technology built in. This makes the process of building a DR site that much easier. However, there is still an amount of planning and management process development that would be required to ensure that in the event of a catastrophe your business will be back up and running in a minimal time frame. Code Blast understands these challenges and the importance of ensuring that the correct technologies and methodologies are in place to best protect your key systems.
