What is Disaster Recovery
Disaster Recovery (DR) refers to the process of recovering access to applications, data, and IT infrastructure functionality after disruptive events like fires, floods, system failures, human errors, or ransomware attacks. The main objective is to quickly restore operations during a disaster and bring systems back to normal. They are closely linked to business continuity and disaster recovery, collectively known as BCDR. Although these terms are often used interchangeably, there is a crucial distinction. While disaster recovery aims to restore technology systems as swiftly as possible, business continuity focuses on keeping the entire organization operational. Therefore, disaster recovery plays a vital role in business continuity strategies.
Types of Disaster Recovery
Companies can select one or multiple disaster recovery methods from the list below:
- Data Backup: Backing up your data is crucial for disaster recovery. Make sure to store your data off-site or on a removable drive regularly.
- Cold-Site: In the event of a disaster, a cold site can provide a basic office setup for your employees to continue working.
- Hot-Site: A hot site keeps real-time copies of your data, allowing you to recover your information from the exact point of disruption.
- DRaaS: Disaster Recovery as a Service (DRaaS) is a cloud service that can move your processing to a vendor’s location if your servers go down.
- Datacenter: Datacentre disaster recovery tools, like fire suppression equipment, help protect your IT equipment in case of a fire.
- Virtualization: Using virtual machines at an off-site location can serve as a backup or replica of your computing environment.
Working Process of Disaster Recovery
In disaster recovery, it is crucial to have a backup of your data stored in a remote location that remains unaffected by any potential disasters. This ensures that even if your IT infrastructure fails due to a natural disaster or a cyber-attack, your business can still retrieve and recover the lost data from this secure location.
Apart from backing up data, organizations can also transfer their computer processing to this remote location to ensure uninterrupted operations. This process, known as failback, allows businesses to sustain their critical functions and continue serving their customers even in the face of adversity.
Why is a Disaster Recovery Plan Important?
The increasing demand for enhanced customer experience and business results is driving the rise of hybrid multi-cloud adoption among businesses. However, this adoption also brings about infrastructure complexities and potential risks that call for specialized expertise and tools for effective management. Due to these complexities, organizations are facing frequent outages, system failures, cyber-attacks, skill shortages, and supplier issues.
The impact of these outages and downtime is particularly severe in a hybrid multi-cloud setting. To ensure resiliency in a hybrid multi-cloud environment, a disaster recovery plan with specialized skills, a cohesive strategy, and advanced technologies such as data protection and recovery orchestration is essential. Businesses need to have a robust enterprise resiliency framework with orchestration technology to mitigate business continuity risks in hybrid multi-cloud environments and successfully achieve their digital transformation objectives.
Key Best Practices of Disaster Recovery
It is crucial to comprehend the optimal methods involved in developing and executing disaster recovery planning, as it aids enterprises in resuming operations with minimal business interruption following data loss or IT equipment failure.
Develop the Plan with a Team of Experts
Creating a successful disaster recovery plan requires collaboration from a diverse group of individuals, both internally and externally. This includes experts who understand the ins and outs of hardware, software, data, and network connectivity. Additionally, it’s crucial to have department leaders and senior management involved in making important policy decisions.
Find the Essential Infrastructure
Make sure to pinpoint the essential software applications, hardware, and data needed for a data recovery plan. Standardized hardware can be used to replicate and reimage new hardware. Ready.gov suggests that companies should have program software available to facilitate reinstallation or replacement of equipment.
Assess and Improve the Disaster Recovery Procedure
A reliable disaster recovery plan is determined by its level of testing, and a plan that hasn’t been tested can give a false sense of security. Just like any other task that requires testing, companies should regularly test their disaster recovery plans. Moreover, as business needs shift and regulations develop, testing can identify areas that require adjustments. Given the importance of this process, it is crucial to allocate a budget for testing evaluation and refinement.
A successful testing activity should include a detailed report outlining the tests conducted, frequency, procedures, and factors contributing to success. When it comes to testing methods, there are various approaches to consider. For example, you could opt for a walk-through test where stakeholders review the plan’s playbook. Another option is a simulation test to assess the plan’s performance under disaster conditions. Additionally, a full interruption test can be used to evaluate the system’s response when it is completely down. To determine success factors, companies can analyze details, knowledge, skills, traits, values, and motivations that impact the effectiveness of the testing process.
Get your Employees and Processes Engaged
Disaster recovery planning goes beyond just information and technology. It also includes people and processes. It’s important for organizations to involve all relevant individuals in the process. One effective method is to integrate disaster recovery tests and drills into the company culture. Additionally, regular employee training and awareness sessions should be conducted.
Automate Workflow
Automation is essential for efficient and speedy disaster recovery in today’s IT infrastructures. Even small organizations manage complex environments with numerous critical nodes and large amounts of valuable data. Manual recovery of these infrastructure arrays is not feasible due to its slow and error-prone nature. Hence, it is crucial to have a suitable disaster recovery solution that can execute your pre-planned strategies with minimal staff involvement.
Conclusion
It’s inevitable for a modern organization to encounter an IT disaster at some point. That’s why it’s crucial for both SMBs and enterprises to adopt the best practices for IT disaster recovery. By doing so, they can ensure that they meet their desired recovery time objectives (RTOs) and recovery point objectives (RPOs), minimizing any potential data loss and downtime in the event of a disruptive incident.
To ensure optimal efficiency in disaster recovery (DR), it is crucial to educate your team members. It is also important to understand the distinction between disaster recovery and business continuity. Once you have a clear understanding, you can define potential threats and prioritize workloads accordingly to create a suitable recovery plan. Additionally, it is advisable to carefully calculate your budget to avoid unexpected financial shortfalls and prevent unnecessary expenses on performance, features, or capacity. Lastly, don’t forget the significance of DR automation, regular testing, and timely fixes to maintain an effective system.
