Redshift deferred maintenance disabled

Risk Level

Informational (4)



Deferred maintenance is disabled for a Redshift cluster. The ""defer maintenance"" attribute of a Redshift configuration allows you to postpone maintenance of a cluster and keep your warehouses running without any interruptions during peak/critical business timespans. The maintenance can be deferred by up to 45 days. If the feature is disabled, you may experience downtime during crucial business periods.
  • Recommended Mitigation

    Consider enabling the “defer maintenance” feature and postpone scheduled maintenance to run during off-peak hours.
