Cluster Deletion Protection

01 Sign in to AWS Management Console.

02 Navigate to RDS dashboard at https://console.aws.amazon.com/rds/.

03 In the left navigation panel, under Amazon RDS, click Databases.

04 Click on the name (link) of the Aurora database cluster that you want to examine. To identify Aurora clusters, check the value available in the Engine column (e.g. Aurora MySQL).

05 On the cluster details page, select Configuration tab and check the Deletion protection configuration attribute value. If the attribute value is set to Disabled, the Deletion Protection safety feature is not enabled for the selected Amazon Aurora database cluster.

06 Repeat step no. 4 and 5 to determine the Deletion Protection feature status for other Amazon Aurora clusters available in the current region.

07 Change the AWS region from the navigation bar and repeat the process for other regions.

01 Run describe-db-clusters command (OSX/Linux/UNIX) using custom query filters to list the names of all Aurora database clusters available in the selected AWS region:

aws rds describe-db-clusters
	--region us-east-1
	--output table
	--query 'DBClusters[?Engine==`aurora`].DBClusterIdentifier | []'

02 The command output should return a table with the requested RDS resource names:

----------------------------
|  DescribeDBClusters      |
+--------------------------+
|  cc-project5-cluster     |
|  cc-serverless-cluster   |
+--------------------------+

03 Execute again describe-db-clusters command (OSX/Linux/UNIX) using the name of the database cluster that you want to examine as identifier and custom query filters to get the Deletion Protection feature status for the selected Amazon Aurora cluster:

aws rds describe-db-clusters
	--region us-east-1
	--db-cluster-identifier cc-project5-cluster
	--query 'DBClusters[*].DeletionProtection'

04 The command output should return the feature status (true for enabled, false for disabled):

[
    false
]

05 Repeat step no. 3 and 4 to check the Deletion Protection feature status for other Aurora clusters available within the selected region.

06 Change the AWS region by updating the --region command parameter value and repeat steps no. 1 – 5 to perform the audit process for other regions.

01 Sign in to AWS Management Console.

02 Navigate to RDS dashboard at https://console.aws.amazon.com/rds/.

03 In the left navigation panel, under Amazon RDS, click Databases.

04 Select the database cluster that you want to reconfigure (see Audit section part I to identify the right Amazon Aurora resource).

05 Click the Modify button from the dashboard top menu.

06 On the Modify DB Cluster: <cluster-identifier> page, in the Deletion protection section, select Enable deletion protection checkbox to activate Deletion Protection for the selected Amazon Aurora cluster.

07 Click Continue to continue the reconfiguration process.

08 Within Summary of modifications section, review the configuration changes that you want to apply to the cluster.

09 In the Scheduling of modifications section, perform one of the following actions based on your requirements:

1. Select Apply during the next scheduled maintenance window to apply the changes automatically during the next scheduled maintenance window.
2. Select Apply immediately to apply the changes right away. With this option any pending modifications will be asynchronously applied as soon as possible, regardless of the maintenance window setting for this Aurora database cluster. Note that any changes available in the pending modifications queue are also applied. If any of the pending modifications require downtime, choosing this option can cause unexpected downtime for your application.

10 Click Modify DB Cluster to apply the configuration changes.

11 Repeat steps no. 4 – 10 to enable the feature for other Amazon Aurora clusters available in the current region.

12 Change the AWS region from the navigation bar and repeat the process for other regions.

01 Run modify-db-cluster command (OSX/Linux/UNIX) to enable Deletion Protection feature for the selected Amazon Aurora database cluster (see Audit section part II to identify the right resource) by adding the --deletion-protection parameter to the command request. The following command example make use of --apply-immediately parameter to apply the configuration changes asynchronously and as soon as possible. Any changes available in the pending modifications queue are also applied with this request. If any of the pending modifications require downtime, choosing this option can cause unexpected downtime for your Aurora-based application. If you skip adding the --apply-immediately parameter to the command request, Amazon Aurora will apply your changes during the next maintenance window:

aws rds modify-db-cluster
	--region us-east-1
	--db-cluster-identifier cc-project5-cluster
	--deletion-protection
	--apply-immediately

02 The command output should return the new configuration metadata for the modified serverless cluster:

{
    "DBCluster": {
		"Status": "available",
		"MultiAZ": false,
		"PreferredBackupWindow": "05:07-05:37",
		"DBSubnetGroup": "default",
		"BackupRetentionPeriod": 7,
		"Engine": "aurora",
		"IAMDatabaseAuthenticationEnabled": false,
		"ClusterCreateTime": "2019-04-10T10:14:45.332Z",
		"EngineVersion": "5.6.10a",

		...

		"DeletionProtection": true,
		"DBClusterIdentifier": "cc-project5-cluster",
		"DbClusterResourceId": "cluster-AAAABBBBCCCCDDDDAAAABBBBCD",
		"DBClusterMembers": [],
		"StorageEncrypted": true,
		"DBClusterParameterGroup": "default.aurora5.6",
		"AvailabilityZones": [
			"us-east-1a",
			"us-east-1c"
		],
		"Port": 3306
    }
}

03 Repeat step no. 1 and 2 to enable the safety feature for other Amazon Aurora database clusters available in the selected region.

04 Change the AWS region by updating the --region command parameter value and repeat the entire process for other regions.
