Amazon Redshift replicates all your data within your data warehouse cluster when it is loaded and also continuously backs up your data to S3. Amazon Redshift always attempts to maintain at least three copies of your data. By default, Amazon Redshift enables automated backups of your data warehouse cluster with a 1-day retention period. You can configure this to be as long as 35 days.

When you need to restore a backup, you have access to all the automated backups within your backup retention window. Once you choose a backup from which to restore, you will be provisioned with a new data warehouse cluster and restore your data to it.
