Enum CfnDeletionPolicy
With the DeletionPolicy attribute you can preserve or (in some cases) backup a resource when its stack is deleted.
public enum CfnDeletionPolicy
Fields
DELETE = 0
AWS CloudFormation deletes the resource and all its content if applicable during stack deletion.
RETAIN = 1
AWS CloudFormation keeps the resource without deleting the resource or its contents when its stack is deleted.
SNAPSHOT = 2
For resources that support snapshots (AWS::EC2::Volume, AWS::ElastiCache::CacheCluster, AWS::ElastiCache::ReplicationGroup, AWS::RDS::DBInstance, AWS::RDS::DBCluster, and AWS::Redshift::Cluster), AWS CloudFormation creates a snapshot for the resource before deleting it.
Remarks
You specify a DeletionPolicy attribute for each resource that you want to control. If a resource has no DeletionPolicy attribute, AWS CloudFormation deletes the resource by default. Note that this capability also applies to update operations that lead to resources being removed.
