...strategies: BackoffStrategy[]

Returns BackoffStrategy

// Retry quickly at first, then back off
agenda.define('myJob', handler, {
  backoff: combine(
    // First 2 retries: immediate (100ms)
    (ctx) => ctx.attempt <= 2 ? 100 : null,
    // Then exponential backoff for 3 more attempts
    exponential({ delay: 1000, maxRetries: 3 })
  )
});
