At a time when less-than-great news has become the norm, it’s hard to act surprised when a crisis looms. Although we continue to hope for the best, we’ve all come to expect the worst. That’s why having a disaster recovery plan ready to roll is crucial.
A comprehensive recovery plan will minimize the effect of a natural disaster on business continuity, compliance, and data loss. A good plan also helps speed up recovery from cyberattacks, such as those recently hitting Infosys, Boeing, and Okta.
If your organization’s disaster recovery plan is outdated, insufficient, or worse, nonexistent, let these events motivate you to review, revise, or create a recovery strategy now, before you need it.
So, what is a disaster recovery plan, and what should it include?
Here are eight steps to create a disaster recovery plan that will help prevent data loss, facilitate business continuity, and ensure your sensitive data and SLAs remain compliant.
Step 1: Create a Disaster Response Team and Document Responsibilities
During a crisis, your disaster response team will spearhead recovery efforts and disseminate information to employees, customers, and stakeholders.
Assign each team member specific tasks during the response and document them so everyone knows who oversees what. You will also need backup staff for key team members if a designated lead isn’t available during a crisis.
Step 2: Set Clear RTOs and RPOs
One of the most crucial components of a disaster recovery plan is establishing your recovery time objective (RTO) and recovery point objective (RPO).
RTO is the length of time an application can be down before your business is negatively impacted. RTO varies widely among applications because some can be down for only a few seconds before the business, customers, or users are impacted. In contrast, others can be down for hours, days, or weeks.
RTOs are calculated based on the application’s importance:
- RTO near zero: Mission-critical applications that must failover
- RTO of four hours: Less critical, so there is time for on-site recovery from bare metal
- RTO of eight or more hours: Nonessential applications that can be down indefinitely
Your recovery point objective (RPO) is the most data that can be lost before your business is significantly harmed. This IT disaster recovery plan component dictates how frequently you’ll need to back up your data.
The amount you are willing to spend to back up a particular application also comes into play because as you work to control IT costs:
- RPO of near zero: Use continuous replication (mission-critical data). This requirement will require effective business continuity solutions that virtually eliminate downtime.
- RPO of four hours: Use scheduled snapshot replication
- RPO of 8-24 hours: Use existing backup solution (data that can potentially be recreated from other repositories)
Step 3: Make a Blueprint of Your Network Infrastructure
Creating detailed documentation of your network infrastructure will make it much easier to rebuild the system after a disaster, especially if a cyberattack corrupted the network.
Different system components have different levels of importance to business continuity, so be sure to indicate the priority of each service as mission-critical, essential, or nonessential so they can be restored in the appropriate order. Don’t forget to include system dependencies in your blueprint because they may impact how you prioritize recovery.
Step 4: Select a Disaster Recovery Solution
Storage capacity, recovery timeline, and configuration complexity will affect the cost of a disaster recovery solution. In many cases, you are choosing between a solution that offers quick recovery times but may lose days of data and a solution that maintains system availability but kills you with high complexity and costs.
Look for a disaster recovery solution like Arcserve Unified Data Protection (UDP) that affordably protects your systems and applications from data loss. Arcserve also minimizes complexity by making it easy to manage backup and disaster recovery and restore service-level agreements using Arcserve Cloud Console, a unified, web-based management interface.
Step 5: Create a Checklist of Criteria for Initiating the Disaster Response Plan
Only some incidents warrant a full-fledged deployment of your disaster response plan. Creating a checklist of criteria to identify what constitutes a disaster helps your recovery team know when it’s time to jump into action without wasting resources or money by overreacting to a minor threat.
For example, a temporary power outage and a direct hit from a category four hurricane require very different responses.
Step 6: Document the Disaster Recovery Process
To ensure data and operations are restored quickly after a disaster, create step-by-step instructions in plain language so your team can start the disaster recovery effort as soon as it’s safe.
Store a copy of the disaster recovery plan away from the network or in immutable storage to protect it from corruption during a ransomware attack or physical loss from a natural disaster.
Step 7: Test Your Disaster Recovery Plan
Regularly test your disaster recovery plan to ensure it will work when needed. Run a partial recovery test twice a year and a full recovery simulation annually.
It also doesn’t hurt to periodically spring surprise drills on the company so you can accurately assess how well the processes will work in a real emergency.
Step 8: Review and Update Your Disaster Recovery Plan Regularly
Your disaster recovery plan needs to be reviewed and updated regularly to reflect organizational changes and how they impact the recovery process. For disaster recovery plan example steps, check out our eBook How to Build a Disaster Recovery Plan.
