backupRetentionPeriod

The number of days to retain automated backups. Setting this parameter to a positive number enables backups. Setting this parameter to 0 disables automated backups.

Enabling and disabling backups can result in a brief I/O suspension that lasts from a few seconds to a few minutes, depending on the size and class of your DB instance.

These changes are applied during the next maintenance window unless the ApplyImmediately parameter is enabled for this request. If you change the parameter from one non-zero value to another non-zero value, the change is asynchronously applied as soon as possible.

This setting doesn't apply to Amazon Aurora DB instances. The retention period for automated backups is managed by the DB cluster. For more information, see ModifyDBCluster.

Default: Uses existing setting

Constraints:

• Must be a value from 0 to 35.

• Can't be set to 0 if the DB instance is a source to read replicas.

• Can't be set to 0 for an RDS Custom for Oracle DB instance.
