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
