Instant recovery takes advantage of continuous data protection to provide simultaneous data backup and disaster recover. The instant recovery of virtual machines (VMs) utilizes numerous technologies for both virtualization and storage. However, we will first discuss the convergence of data backup and disaster recovery in Part 1.

Backup Evolution

In existence as long as IT, the technology of data backup has stayed mostly static for many years. Although there have been upgrades in the capacity and performance of backups and applications, the core ideas have stayed the same. Purposed to copy data at points of time, backups were used for restoration following catastrophic losses. However, there has been a rapid evolution during the last 10 years due to technological advances like virtualization. As a result, current software for backup is quite different from what was available before the leap.

The evolution of backups has been in several areas, but the most significant involves data backup and disaster recovery converging, which led to the creation of instant recovery. Backup’s technological purpose was to recover data which would have been lost without it. Typical recovery involved failures of storage, accidental overwriting of files, and the restoration of data after unintentional erasure.

Disaster Recovery Overview

As opposed to backup, disaster recovery (DR) concentrates on business continuity. The majority of DR initiatives have the main goal of restoring the function of information systems after a disaster. Should a company’s data center be destroyed by a natural disaster, for example, the company can transfer workloads to another data center or the cloud to return critical systems online, so that it may conduct business. In any case, disaster recovery and data backup are alike in an important way. They are both considered contingency plans in case of disaster. Moreover, DR typically utilizes backup media, and it is deemed a component of the data backup operations of a company.

Convergence of Data Backup and Disaster Recovery

As the distinctions between data backup and disaster recovery have become hazy, it should not be astonishing there has been a convergence of the two. Nowadays, backups involve the creation of recoverable data copies, while disaster recovery involves the maintenance of business continuity. Due to their convergence, an organization may now utilize one application for both services.

Part 2 will discuss instant recovery and continuous data protection.
