TL;DR This guide compares 10 data replication tools across CDC, batch and disaster recovery.
Warehouse replication: Airbyte, Fivetran and Hevo Data replicate sources into analytics destinations using change data capture.Enterprise CDC: Qlik Replicate, Informatica and IBM Informix handle high-volume, low-latency replication across legacy databases.Cloud-native: AWS Database Migration Service and Google Datastream suit teams already committed to one provider.Disaster recovery: Dell RecoverPoint and Carbonite replicate for continuity and failover rather than for analytics.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.
