Introduction

Data is the most valuable resource and backbone for any modern business. Customer information, financial data or any business operational information are digital assets that drive the enterprise. Hence, it is crucial to save this business data against loss and threats. That’s why data backup and disaster recovery planning are essential. This blog will guide you about everything related to backup and disaster recovery planning- from their meaning to why they are important and how businesses can implement these strategies.

Understanding Backup and Disaster Recovery

Data backup and disaster recovery are indispensable parts of any business due to the importance and sensitivity of the data involved. Let’s understand data backup and disaster recovery in detail.

What is Data Backup?

Data backup, in layman’s terms, is basically a process of making copies or duplicating important business data. This practice safeguards the data against any potential loss. This loss can occur due to numerous reasons like an accident, corruption or destruction due to natural disasters. 

There are many types of backup strategies that can be implemented: Full backup, incremental backup and differential backup.

• Full Backup: This type of backup captures and duplicates all data in a single operation. Making full backups can be time-consuming and requires intensive storage.
• Incremental Backup: In this type of backup, only changes since the last backup are stored. It saves time and storage.
• Differential Backup: Differential backup captures changes since the last full backup. It is faster than full backup and larger than incremental backups.

What is Disaster Recovery?

Disaster recovery is the process of restoring essential business data following a disruptive event like a cyberattack, hardware issues, human error or natural disaster. Although data backup and disaster recovery are related, they differ in many aspects including purpose and scope.

Data backup duplicates data to ensure that business data is available while disaster recovery is focused on reducing downtime and operational continuity.

The Risks of Not Having a Backup and DR Plan

Businesses can be at intensive risk if they do not have a robust backup and disaster recovery plan implemented. Some primary threats include:

Data Loss Causes

• Cyberattacks like viruses, ransomware and other malicious attacks can halt the business systems.
• It is possible that hardware including systems, hard drives, servers and other devices fail due to power fluctuations or out of nowhere.
• Natural disasters like floods, fires, and earthquakes are out of anyone’s control but can disrupt business operations drastically by damaging physical infrastructure.
• Employees can accidentally or mistakenly delete or make misconfigurations which can result in data loss

Consequences of Data Loss

• Data loss can drastically impact in monetary terms such as loss of business, and additional cost of restoring operations.
• Businesses are at risk of losing customer trust and business reputation if sensitive data is lost or leaked.
• Businesses may also face legal consequences or penalties in case of loss of sensitive data like the personal and financial information of customers. 

Key Components of a Backup and Disaster Recovery Plan

An effective backup and disaster recovery plan is one that is inclusive, comprehensive and customised to your business needs. Below are some of the key components that should be considered while doing backup and disaster recovery planning:

• Assessing Business Needs: The first step is to identify sensitive and critical business data and systems that are essential for business operations. Then assess potential risks and vulnerabilities that could affect the business continuity. 
• Developing a Backup Strategy: According to the sensitivity and criticality of data decide on the frequency of data backups. It should be made sure that backups are created automatically to avoid any failure. Once the frequency is fixed, on-premises and cloud options should be evaluated and compared.
• Creating a Disaster Recovery Plan: Once the strategy is decided, Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) should be established. RTO is dedicated to resuming operations quickly so that productivity and revenue are not hampered while RPO is focused on minimising the amount of data loss.
• Testing and Updating Disaster Recovery Plan: The process of backup and disaster recovery planning does not end at implementation. The plan should be regularly tested to identify the gaps and update with the necessary changes.

Benefits of Disaster Recovery

Being proactive has always proved to be beneficial for businesses. Having a backup and disaster recovery plan has multiple benefits including:

1. Reduction in Downtime: Whenever any disaster happens, productivity, customer trust and company’s reputation come at stake. A robust disaster recovery plan helps in recovering in minimal possible time.
2. Better Business Continuity: A disaster recovery plan forms a part of business continuity planning and ensures that operations are resumed quickly without disrupting business continuity.
3. Enhanced Security: A disaster recovery plan is primarily focused on securing important and sensitive data for the business from getting lost or corrupted.
4. Better Regulatory Compliance: It may also be under regulatory compliance for a business to have a strong disaster recovery plan in place. It should be tested regularly to avoid loss of valuable data and customer trust.
5. Reduction in Recovery Costs: The financial effect of data loss or corruption can be significant. These costs include loss of business, penalties for ransomware, etc. A disaster recovery plan can save or reduce these costs. 

Best Practices for Effective Backup and Disaster Recovery

There are multiple practices that businesses follow for effective backup and disaster recovery. Some of the most common practices are as follows:

• Automating Backups: It is not enough to implement a backup and disaster recovery plan. It should be made sure that backups are automated and created without any human intervention. Automation should happen at regular intervals, say at the end of the day or weekly, as per the intensity required.

• Regular Testing of Disaster Recovery Plans: Effective backup and disaster recovery planning does not end as placement. It should be regularly tested through simulations and drills. Testing is important to identify gaps and make necessary changes.

• Keeping Multiple Backup Copies: Automated offsite and online backups mean that disaster needn’t be disastrous for your business. For offsite storage, the data centre should be based at a location which is highly secured. For online backups, cloud storage is the best option that provides flexibility, scalability and accessibility from any location.
• Documentation and Communication: It is important that backup and disaster recovery plans should be properly documented. This documentation should be communicated to all the concerned stakeholders to make them aware of their roles and responsibilities.

Technologies Supporting Backup and Disaster Recovery

With emerging awareness and the need for backup and disaster recovery, more and more technologies are supporting backup and disaster recovery planning. From offsite to online backups, every business can choose the one according to their budget and requirements. There are offsite backup solutions that create backups of business data at secure remote locations and online cloud-based solutions like Google Cloud and Microsoft Azure.

Advantages of Cloud-based Solutions

Cloud-based solutions for backup and disaster recovery are being widely used due to their benefits:

• Online cloud backups allow businesses to scale their storage without investing in additional backup hardware. It further provides flexibility for businesses with growth projections.
• Cloud-based solutions operate on a pay-as-you-go model. Hence businesses are saved from investing in hardware, software, and IT staff for backups and disaster recovery.
• In case of regional disruptions, cloud-based backup solutions reduce the risk of data loss as data can be accessed from multiple geographical locations.
• Disaster recovery through online cloud-based solutions is comparatively easier and faster than traditional forms of backup.

Emerging Technology: AI in Data Recovery

AI or Artificial Intelligence is transforming the process of data recovery in case of disaster recovery planning. Key advancements of AI in data recovery include:
