Disaster can strike a business at any moment. Research shows that without preparation and data protection, over 50% of businesses will not survive a major disaster. It is crucial to assess your IT infrastructure and understand what information security measures you can take to decrease the damage caused by a disaster and recover operations quickly. Learn about four essential elements you must include in your disaster recovery program for it to be effective. Show

What is Disaster Recovery?Disaster recovery is the practice of anticipating, planning for, surviving, and recovering from a disaster that may affect a business. Disasters can include:
What is a Disaster Recovery Plan?A disaster recovery plan enables businesses to respond quickly to a disaster and take immediate action to reduce damage, and resume operations as quickly as possible. A disaster recovery plan typically includes:
Why is Disaster Recovery Important?Drafting a disaster recovery plan, and ensuring you have the right staff in place to carry it out, can have the following benefits:
What Is the Difference Between Disaster Recovery and Business Continuity?Business continuity (BC) and disaster recovery (DR) are often grouped into one corporate identity called BCDR. However, while the two share similar objectives that help improve the organization’s resiliency, business continuity and disaster recovery differ in scope. Business continuity is a proactive approach to minimizing risks and ensuring the organization can continue to deliver products and services regardless of the circumstances. BC primarily focuses on defining ways to ensure employees can continue their work and enable the business to continue operations during disaster events. Disaster recovery is a subset of BC focused mainly on the IT systems required for business continuity. DR defines specific steps needed to resume technology operations after an event occurs. It is a reactive process that requires planning, but organizations implement DR only when a disaster truly occurs.

Know Your ThreatsLearn about the history of your business, the industry and the region, and map out the threats you are most likely to face. These should include natural disasters, geopolitical events like wars or civil unrest, failure to critical equipment like servers, Internet connections or software, and cyber attacks that are most likely to affect your type of business. Ensure your disaster recovery plan is effective against all, or at least the most likely or most significant threats. If necessary, develop separate DR plans or separate sections within your DR plan for specific types of disasters. 2. Know Your AssetsIt’s important to be comprehensive. Get your team together and make a big list of all the assets that are important for the day-to-day operations of your business. In the IT sphere this includes network equipment, servers, workstations, software, cloud services, mobile devices, and more. Once you have your list organize it into:
3. Define Your RTO and RPODefine your Recovery Time Objective (RTO) for critical assets. What period of downtime can you sustain? For example, a high traffic eCommerce site sustains major financial damage for every minute of downtime. An accounting firm may be able to sustain a day or two of downtime and resume normal operations, provided there is no data loss. Build a process and obtain technological means that can help you bring operations back online within the RTO. The term recovery point objective (RPO) refers to the maximum age of files the organization must recover from backup storage to resume normal operations after a disaster occurs. Organizations use RPO to determine the minimum frequency of backups. For example, a four-hour RPO requires backing up at least every four hours. 4. Set Up Disaster Recovery SitesA cornerstone of almost every disaster recovery plan is having a way to replicate data between multiple disaster recovery sites. While many businesses schedule periodic data backups, for disaster recovery purposes, the preferred approach is to continuously replicate data to another system. Data may be replicated to:
Local storage is less resilient to disaster but gives you a shorter RTO. It also allows you to replicate or backup data more frequently, improving your Recovery Point Objective (RPO) – meaning you can restore your data from almost every point in time. 5. Test Backups and Restoration of ServicesJust like business systems can fail in a disaster, so can backups. There are many horror stories of organizations that had a backup system in place, but discovered too late that backups were not actually working properly. A configuration problem, software error or equipment failure can render your backups useless, and you may never know it unless you test them. An inseparable part of any disaster recovery plan is to test that data is being replicated correctly to the target location. It’s just as important to test that it’s possible to restore data back to your production site. These tests must be conducted once, when you set up your disaster recovery apparatus, and repeated periodically to ensure the setup is still working. Building Your Disaster Recovery PlanHere are key steps to help guide you through the process of creating a disaster recovery plan: Risk AssessmentA disaster recovery plan should start with business impact analysis (BIA) and risk assessment that address the relevant potential disasters. Here are key aspects of considerations:
Evaluate Critical NeedsOnce you have completed a risk assessment, you need to evaluate the critical needs of each department and establish priorities for operations and processing. It involves creating written agreements for predetermined alternatives and specifying the following details:
Set Disaster Recovery Plan ObjectivesHere are key aspects to help you set disaster recovery plan objectives:
Collect Data and Create the Written DocumentData helps create informed and relevant disaster recovery plans. Here are key data types to collect at this stage:
Organize and include this data in a written, documented plan. Test and ReviseA disaster recovery plan should remain theoretical – you need to regularly test and revise the plan to ensure it remains relevant. Testing can help obtain the following benefits:
Here are several types of disaster recovery plan tests you can employ:
Before running the test, you should determine the criteria and procedures for testing your disaster recovery plan. After choosing a test, you should conduct a structured walk-through test or an initial dry run and correct any issues. Ideally, you should run this run dry outside normal business hours to avoid disrupting work.

The scale and vision of an organization’s DR plan may require specific teams for departments like networking or data centers. Here are some examples of DR solutions: Data Center Disaster RecoveryA data center DR strategy is essential for organizations that store their data in an on-prem data center. This strategy addresses the security of an organization’s physical and IT infrastructure in addition to the data backups. An important aspect of this strategy is a backup to a failover site at a secondary location. Organizations should document and devise methods and procedures when facilities-related issues affect electrical, heating/cooling, physical security, and fire safety systems. Network Disaster RecoveryNetwork connectivity is vital to maintain communication, application access, and data sharing in a disaster. A plan to restore network services is an essential component of a network DR strategy. This strategy should emphasize access to backup data and sites. Cloud Disaster RecoveryThe rise of the cloud has attracted organizations that would have traditionally used a secondary physical location to host their DR. Cloud-hosted DR is an alternative that provides more than a simple cloud backup. A proper cloud DR strategy requires an IT team to implement automatic workload failover to a public cloud in the event of a disaster. Related content: Read our guide to disaster recovery in the cloud Virtualized Disaster RecoveryA virtualized disaster recovery strategy replicates workloads to an alternative physical or cloud-based location. Virtualization offers flexibility and is fast, efficient, and easy to implement – a virtualized workload has a smaller IT footprint and allows for frequent replication and quick failover. Various data protection providers offer virtual backup and disaster recovery products. Disaster Recovery as a Service (DRaaS)DR as a Service is a cloud-based commercial service provided by a third party that replicates and hosts an organization’s virtual and physical servers. According to the service-level agreement (SLA), the provider is responsible for implementing and managing the DR strategy in the event of a disaster.
