Configuration backups for Aiven for Apache Kafka®

Aiven for Apache Kafka® includes configuration backups that automatically back up key service configurations at no additional cost.

By eliminating the need for manual reconfiguration, Aiven for Apache Kafka® configuration backups streamline disaster recovery and service restoration. This ensures a reliable way to restore your service configurations after an incident or when powering off/on your service, saving you valuable time and resources.

What is backed up​

Configuration backups cover the following components of your Aiven for Apache Kafka service:

  • Apache Kafka topics configurations: Including related configuration parameters such as retention time and number of partitions.
  • Apache Kafka users and ACLs: User permissions and access control lists are included.
  • Schema Registry data: Including schema definitions, schema IDs, configurations (such as compatibility level), subjects, and subject versions.
  • Apache Kafka Connect configurations: Includes all related settings.

How backups work​

  • Automatic backups: Backups are enabled by default and stored in cloud storage every 3 hours.
  • Encryption: Backups are encrypted for security, preventing direct access by users.
  • Automatic restoration and configuration retention: Configuration backups are automatically restored (using the latest backup) after a power off/on cycle. This ensures your service configurations are retained and ready for use.

Limitations​

While configuration backups offer significant benefits, there are some limitations:

  • No data backups: Configuration backups do not include the actual data stored in classic topics, consumer groups, and their offsets. Only the cluster configurations are backed up. Diskless topics support full restoration of data and configuration because topic data is stored in object storage.
  • Latest backup restoration: Restoration is always from the latest backup available. You cannot choose a specific backup for restoration.
