Apache Kafka Backup: Everything You Need To Know [Video]

Backup Strategies for Apache Kafka

Several strategic approaches exist for backing up Kafka clusters. The most common methods include topic-based backup, where individual topics are backed up separately, and cluster-wide backup, which creates comprehensive snapshots of the entire deployment. Organizations can also implement periodic snapshots of broker storage, though it requires careful coordination to maintain data consistency. Each strategy presents different trade-offs between complexity, resource utilization, and recovery time objectives (RTO).

Backup Tools and Techniques

The Kafka ecosystem offers various tools for implementing backup solutions. Kafka Connect provides a framework for building scalable backup systems through its source and sink connectors. Popular tools include:

Kafka Connect S3 Sink for cloud-based backups
Google Cloud Storage Sink Connector based backup
Another way to backup a Kafka cluster is to set up a second cluster and replicate events between topics in the cluster.

The choice of tool depends on factors such as data volume, backup frequency requirements, and infrastructure constraints.
