Description:

This policy ensures that all critical system components have a backup schedule in place. This is important to protect data in the event of a disaster or accidental deletion.

Rationale:

A backup schedule ensures that critical system components are backed up on a regular basis. This can help to reduce the risk of data loss and improve the efficiency of the backup process.

Impact:

The impact of not having a backup schedule in place for critical system components can be significant. In the event of a disaster, data may be lost permanently. Additionally, if data is accidentally deleted, it may be difficult or impossible to recover.

Default Value:

AWS recommends that all critical system components have a backup schedule in place. The frequency of the backups will vary depending on the specific component, but AWS recommends that critical components be backed up at least daily.

Pre-requisites:

To implement this policy, you will need to have access to the AWS Management Console or the AWS CLI. You will also need to have the appropriate permissions to create and manage backups.

Remediation Steps:

The following steps can be used to remediate this policy:

  1. Identify the critical system components that need to be backed up.
  2. Determine the frequency of the backups.
  3. Create a backup schedule.
  4. Test the backup schedule.
  5. Document the backup schedule.

Test Plan:

The following steps can be used to test the backup schedule:

  1. Run the backup schedule.
  2. Verify that the backups have been created correctly.
  3. Restore the backups to a test environment.
  4. Verify that the data has been restored correctly.

Implementation Plan:

The following steps can be used to implement this policy:

  1. Create a backup schedule for each critical system component.
  2. Test the backup schedules.
  3. Document the backup schedules.

AWS CLI Process:

The following command can be used to create a backup schedule using the AWS CLI:

aws backup create-backup-schedule --name my-backup-schedule --schedule "cron(0 0 * * ? *)" --resource-types my-ec2-instance my-s3-bucket

Using AWS GUI:

The following steps can be used to create a backup schedule using the AWS Management Console:

  1. Go to the AWS Management Console.
  2. Click on the "Backup" service.
  3. Click on the "Backup Plans" tab.
  4. Click on the "Create Backup Schedule" button.
  5. Enter the name of the backup schedule.
  6. Select the schedule for the backups.
  7. Select the resource types that you want to back up.
  8. Click on the "Create Backup Schedule" button.

Backout Plan:

The following steps can be used to revoke the changes made to implement this policy:

  1. Delete the backup schedule.

Note:

  • This policy is not intended to replace the need for a comprehensive disaster recovery plan.
  • This policy is specific to AWS resources. Other resources, such as on-premises servers, may require different backup and restoration procedures.
