Quick Example​

Backup a Topic​

# Create a backup configuration
cat > backup.yaml << EOF
mode: backup
backup_id: "my-first-backup"

source:
  bootstrap_servers:
    - kafka:9092
  topics:
    include:
      - orders
      - payments

storage:
  backend: filesystem
  path: "/var/lib/kafka-backup/data"

backup:
  compression: zstd
EOF

# Run the backup
kafka-backup backup --config backup.yaml

Restore with Point-in-Time Recovery​

# Create a restore configuration with time window
cat > restore.yaml << EOF
mode: restore
backup_id: "my-first-backup"

target:
  bootstrap_servers:
    - kafka-dr:9092

storage:
  backend: filesystem
  path: "/var/lib/kafka-backup/data"

restore:
  time_window_start: 1701417600000  # Dec 1, 2024 10:00 UTC
  time_window_end: 1701504000000    # Dec 2, 2024 10:00 UTC
EOF

# Run the restore
kafka-backup restore --config restore.yaml

What's New​

  • Kafka Backup v0.22.0 - backup.on_missing_topic: warn to skip absent topics, describe/validate --config, S3 path_style honoured and http:// endpoints imply allow_http, offset_storage.sync_interval_secs honoured (ignored keys now warn); v0.21.0 added safe retention (kafka-backup prune, backup.retention) and the restore record-filter hook behind the Enterprise GDPR erasure feature
  • Strimzi Backup Operator v0.3.1 - Stable kafkabackup.com/v1 API (v1alpha1 served but deprecated), CRDs rendered by the Helm chart so upgrades apply them, default job image osodevops/kafka-backup:v0.22.0, published API stability, support and security policies
  • Kafka Backup v0.19.2 - restore.strip_offset_headers for header-for-header identical restores, the backup logs the offset headers it adds, compressed legacy JSON segments restorable again; v0.18.0 fixed null header values being archived as empty
  • Kubernetes Operator v1.3.0 - Uses kafka-backup-core v0.19.2; KafkaRestore exposes includeOriginalOffsetHeader and stripOffsetHeaders
