Data is currently the most valuable asset, which is why protection against its loose or theft becomes crucial challenge. Implementing proper practices related to data security is one of the fundamental priorities in every organization. Entrepreneurs, aiming to protect their sensitive resources, most often opt for backup and replication. However, even though terms are sometimes used interchangeably, they actually represent two completely different strategies, each serving a unique role in data protection.
Backup – how does it work?
Backup is the process of creating data copies and storing them in a separate location, providing protection against loss due to failures, user errors, cyberattacks or other incidents. Backup may be stored on local storage device or in the cloud. The process of creating backup enables the system to be restored to a previous state, which is crucial in crisis situation. Losing business data may lead to financial, reputational and legal consequences, making the implementation of a proper backup strategy essential.
Replication – what is it?
Data replication is a process, that focuses on creating exact copies of data and transmitting them to another location in real-time or near real-time window, following a change in the data source. It is a method of protecting resources, involving the transition of data in an unchanged form between independent data centers. It ensures data availability in the event of failure in one of the server rooms. Replication is typically used in situation, where the priorities are maintaining operational continuity and minimizing downtime. It is an ideal solution for organizations that need to encure continuous access to the services.
Key difference
Although both services may appear similar, they are different from each other. Replication focuses on maintaining exact copies of data in multiple locations, ensuring business continuity and fast recovery. On the other hand, backup is the process of creating copies and storing them to guard against loss. The crucial distinction lies in the fact that backup allows for reverting to a previous state, while replication focuses on data currency and availability.
