Project Description

Backup / Replication

In order to understand the definitions of backup and replication, it is necessary to touch upon the definitions of Disaster Recovery and Business Continuity.

Disaster Recovery (DR) is the process of restarting your business after a corruption event. This could include a natural disaster such as an earthquake or a hurricane, or it could be caused by a cyberattack, such as infrastructure failure.

Business Continuity (BC) describes the processes and procedures the organization has established to ensure that important functions in business processes continue during and after a disaster. The aim is to prevent disruption of critical services and to restore all functions as quickly and smoothly as possible.

Backup involves making a copy or copies of production data. Backup requires disk or tape based solutions and needs a place to store archived tapes.

The whole point of having a backup copy is for compatibility and detailed recovery requirements like recovering a user’s data from three years ago. Basically, the concept is based on snapshot technology, where copies of datasets are taken at a predetermined time and stored regularly. Sometimes old backups are replaced by new backups, and often each backup set is treated as a different entity.

In other words, the aim is to be able to work with zero loss of production data against dangers such as cyber attacks, data thefts and natural disasters. But making backup copies is not the only step in ensuring business continuity.

Replication is the act of copying data to a remote device or platform. Therefore, replication requires investing in another device or identical infrastructure, which can almost double the IT infrastructure costs. It usually scales with Recovery Time Objective (RTO) and Recovery Point Objective (RPO). The gain sought to be achieved with replication is to focus on business continuity, which enables operations to be revived quickly and easily after a disaster or similar scenarios.
