Storing business data is a challenge that all IT managers face. Ensuring data security and its access is critical, and this is possible through data replication and backups. Rapid recovery after a disaster is essential for the business to remain operational and prevent data loss. In this article, we will understand how important data replication is in backing up your information.
What is data replication?
Data replication is the development of a backup structure between equipment that is located in different places but connected by a central data network or storage. Replication is advised in any database software such as MySQL, Oracle, SQL Server, among others. The main purpose of data replication is to ensure greater availability and reliability of the system used. Information security, more than ever, is a prime point. If there is a dependency between equipment, private data traffic on unsafe networks is also there, so greater care is required to avoid data loss. Data replication is one step ahead of conventional backup as it enables data management and enables the destruction of the environment where information was stored.
How does the data replication process work?
Data replication is usually integrated into the virtualization or storage tool. The operation is simple: you create a synchronous or asynchronous replica of the data and then this replica is sent to a different location. The server to which the replica is sent may be in the same building or anywhere in the World. What is essential is that the replica is constantly updated, with a permanent “mirror” between the original version and the copied version. Thus, in the event of a natural disaster or hacker attack, you can recover damaged data without disruption to normal business operations.
What types of replication are there?
- Active – Active: In this situation, data is stored in two data centers, which gives the organization greater security because there is less risk of losing information.
- Active-passive: In this mode, replication is done through synchronization. This process does not always happen in real time and it can cause problems in case of computer attack or natural disaster. Unlike asset-asset, in this scenario there is a greater likelihood of losing valuable information.
