Disaster Recovery Planning - Tips to Help
Organizations I have worked with typically find themselves lacking a disaster recovery (DR) plan for an assortment of reasons. They have never had an outage; Disasters are too numerous to plan for; It is too expensive; They have one - it is called backups; Etc.
Technology has evolved to a point where every company, big and small, now has access to affordable and effective disaster recovery solutions. It doesn't take much to protect your organization from extinction due to a disaster. The following are a few things to think about when devising your organization's recovery plan.
#1 Disasters can and will happen and they don't announce themselves.
- Your organization is not impervious to disasters.
- You don't need to plan for disasters, you need to plan for the results of the disaster. Power outages; Datacenters destroyed; Loss of connectivity.
#2 Disaster recovery plans are a subset of a quality business continuity plan.
- The C-Suite needs to understand and be part of the solution.
- They need to buy into the plan, support the plan and fund the plan.
- They along with other business personnel need to determine recovery time objectives (RTO) and recovery point objectives (RPO) for each application.
- Depending on your RTO & RPO, you will be able to recommend the disaster recovery method to use for each application.
- Some different methods are Active-Active, Active-Standby and Active-Recovery.
- Large organizations will reduce costs by implementing tiered disaster recovery planning and methods.
#3 Having a documented plan that you can follow is half the battle.
- You do NOT want to be attempting to figure out what system to bring on line first during the chaos the occurs before, during and after a disaster.
- The plan should be socialized with anyone that has a role in recovery.
- Create step-by-step runbooks designed for someone who doesn't know the system to follow as the person responsible may not be available.
- Your plan/runbooks should document who, what, how, when and where.
- The runbook should define what systems should be brought up first, second, third, etc. as well as provide architectural diagrams.
- DO NOT SAVE security credentials in the plan or runbook.
#4 You must implement the technology required by the plan.
- Having a backup of your data is terrific, but if you have no way to restore the data and further, nowhere to restore the data to, how do you recover?
- You need target hardware, appropriate licensing and logistical coordination.
#5 Test your plan regularly.
- The solution you choose should be a solution that you can exercise on a regular basis.
- There are many ways to slice and dice a solution. It is very possible to create a plan that is testable.
#6 Choose an appropriate recovery site.
- Selection of the site at which you plan to recover systems is critical.
- Distance between your primary site and secondary site can vary, however, to avoid a single disaster affecting both sites, a distance of 105 miles between them is recommended.
- There are a number of variables you should consider when selecting a secondary site such as accessibility and latency.
If you don't have a DR background, I suggest working with a professional that is experienced.
