Ensure that the automated snapshot retention period set for your AWS Redshift clusters is a positive number, meaning that automated backups are enabled for the clusters. The retention period represents the number of days to retain automated snapshots. If the retention period is set to zero, automated snapshots are disabled for your Redshift clusters. You can still create manual backups when automated snapshots are disabled (retention period set to 0), however, automated actions are more reliable than manual processes, helping you to improve Redshift data protection and recoverability.

When the retention period is set to a positive number within a Redshift cluster configuration, the automated snapshots are enabled for that cluster. Cloud Conformity strongly recommends to automate backups for data recovery whenever possible in order to avoid unexpected failures.
To determine if your Amazon Redshift clusters are taking snapshots of their data automatically (i.e. automated snapshot retention period is set to a positive number), perform the following:
