When you modify a snapshot schedule, the schedule is To precisely control when snapshots are taken, you can create a snapshot schedule andĪttach it to one or more clusters.

You can set an RA3 node type automated retention period from 1–35 days. You can't disable automated snapshots for RA3 node types. If you disableĪutomated snapshots, Amazon Redshift stops taking snapshots and deletes any existing automated To disable automated snapshots, set the retention period to zero. You can modify it by using the Amazon Redshift console or programmatically by using the Amazon Redshift The default retention period is one day, but Automated snapshots are enabled by default when you create a cluster.Īre deleted at the end of a retention period. If you're using custom schedules, the minimum amount of timeīetween automated snapshots is one hour. Alternatively, you can create a snapshot schedule to control when automated snapshots are Is larger than 5 GB * the number of nodes, the shortest amount of time in between automated snapshot creation Hours or following every 5 GB per node of data changes, or whichever comes first.
