TL;DR Short answer: decide first whether you are replicating for analytics or for failover, because the two sets barely overlap. Analytics wants log-based CDC into a warehouse; disaster recovery wants block-level copies and automatic failover. A tool built for one is usually poor at the other. Ten tools:
Airbyte Fivetran Informatica IBM Data Replication Qlik Replicate Hevo Data Dell RecoverPoint Carbonite AWS Database Migration Service Google Datastream Data replication tools copy data from a primary database to one or more replicas, either continuously or on a schedule, so the same records are available in more than one place. That underpins two very different goals: keeping analytics current without hammering production, and staying available when something fails. The ten tools below cover both, along with the criteria that separate them.
What is data replication? Database replication is a pivotal function in data management, involving the movement of data from a primary database to one or more replica databases. This replication process can occur in real-time, continuously monitoring changes in the primary database. Alternatively, it can be executed periodically or as one-time batch processes.
The primary goal of database replication is to enhance data availability, which is critical for improving analytics capabilities and ensuring effective disaster recovery. By replicating data across multiple databases, organizations can minimize downtime and maintain business continuity in the event of system failures or disruptions.
Which data replication tools should you consider? Data Replication is an important process for maximizing analytics output. Choosing the right data replication tool is even more important. Here are 10 of the best data replication tools to consider.
