How Does Virtualization Help With Disaster Recovery

Virtualization empowers organizations to replicate entire IT infrastructures, offering a lifeline during disasters by creating virtual machines (VMs) that can be easily backed up and restored in the event of a disaster. This technology is quickly becoming a crucial part of the disaster recovery plan, ensuring swift recovery for business continuity. But what is virtualization, and how does it help with disaster recovery?

This article discusses virtualization, its vital role in disaster recovery, and effective recovery strategies to reduce downtime and ensure business continuity after a disaster.

What is Virtualization?

Virtualization is a technology used to create a virtual version of physical machines, physical servers, and other computing systems, mimicking their core features and operations. It replicates physical hardware, allowing users to run multiple virtual machines (VM) simultaneously. Thus, they enhance the capability of physical hardware, leading to better efficiency.

Virtualization and Disaster Recovery Plan

Virtualization is not enough to protect your data during a disaster. It only supports your disaster recovery plan. Thus, an organization must have a strategic plan for data loss caused by disasters like fire, security breaches, hardware failure, and natural disasters.

A data recovery plan (DRP) is a structured approach that describes how an organization will respond quickly to resume activities after a disaster that disrupts the usual flow of activities. A vital part of your DRP is recovering lost data.

Virtualization helps you protect your data online through virtual data recovery (VDR). VDR is the creation of a virtual copy of an organization’s data in a virtual environment to ensure a quick bounce back to normalcy following an IT disaster.

While having a virtual data recovery plan is good, you must also provide an off-site backup for a wholesome data recovery plan that can adequately prevent permanent data loss. An off-premises backup location provides an extra security layer in the event of data loss. Thus, you shouldn’t leave this out when planning your data recovery process.

Let’s try to look at this issue in a general way, knowing how diverse and capacious the issue of virtualization and disaster recovery is. Certainly, implementing a dedicated data protection solution will help streamline data protection and disaster recovery processes.

Benefits of Virtualization for Disaster Recovery

Virtualization plays a crucial role in disaster recovery. Its ability to create a digital version of your hardware offers a backup in the event of a disaster. Here are some benefits of virtualization for disaster recovery.

• Recover Data From Any Hardware

If your hardware fails, you can recover data from it through virtualization. You can access your virtual desktop from any hardware, allowing you to recover your information quickly. Thus, you can save time and prevent data loss during disasters.

• Backup and Restore Full Images

With virtualization, your server’s files will be stored in a single image file. Restoring the image file during data recovery requires you to duplicate and restore it. Thus, you can effectively store your files and recover them when needed.

• Copy Data to a Backup Site

Your organization’s backups must have at least one extra copy stored off-site. This off-premise backup protects your data against loss during natural disasters, hardware failure, and power outages. Data recovery will help automatically copy and transfer files virtually to the off-site storage occasions.

• Reduce Downtime

There’s little to no downtime when a disaster event occurs. You can quickly restore the data from the virtual machines. So recovery can happen within seconds to minutes instead of an hour, saving vital time for your organization.

• Test Disaster Recovery Plans

Virtualization can help you test your disaster recovery plans to see if they are fail-proof. Hence, you can test and analyze what format works for your business, ensuring you can predict a disaster’s aftermath.

• Reduce Hardware Needs

Since virtualization works online, it reduces the hardware resources you need to upscale. With only a few hardware, you can access multiple virtual machines simultaneously. This leads to a smaller workload and lower operation costs.

• Cost Effective

Generally, virtualization helps to reduce the cost of funding virtual disaster recovery time. With reduced use of hardware and quicker recovery time, the data recovery cost is reduced, decreasing the potential loss caused by disasters.

Data Recovery Strategies for Virtualization

Below are some practical strategies to help build a robust data recovery plan for your organization’s virtual environment:

• Backup and Replication

Create regular backups of your virtual machines that will be stored in a different location—for instance, an external drive or a cloud service. You can also create replicas and copies of your virtual machines that are synchronized with the original. You can switch from the original to a replica in case of failure.

• Snapshot and Restore

Snapshots capture your data at specific preset moments, creating memories of them. Restore points also capture data but include all information changes after the last snapshot. You can use snapshot and restore to recover the previous state of your data before the data loss or corruption.

• Encryption and Authentication

Encryption and authentication are essential security measures that work in tandem to safeguard data from unauthorized access. By employing both methods, you establish robust layers of defense. This, thereby, fortifies your data against potential cyber threats, ultimately mitigating the risks associated with corruption and theft.

Conclusion

Creating a disaster recovery plan is crucial for every organization as it helps prevent permanent data loss in the event of a disaster, leading to data loss or corruption. Virtualization helps in data recovery by creating a virtual copy of your hardware that can be accessed after a disaster.

Virtualization reduces downtime, helps to recover data from the hardware, reduces hardware needs, and facilitates testing your data recovery plans. However, you must note that virtual data recovery is only a part of a failproof disaster recovery plan. You must make provisions for an off-premises backup site for more robust protection.
