AWS Backup is a fully managed backup service that makes it easy to centralize and automate the backup of data across AWS services in the cloud and on premises. Using AWS Backup, you can configure backup policies and monitor backup activity for your AWS resources in one place.

Backup plan and selection

In AWS Backup, a backup plan is a policy expression that defines when and how you want to back up your AWS resources, such as Amazon DynamoDB tables or Amazon Elastic File System (Amazon EFS) file systems. You can assign resources to backup plans, and AWS Backup automatically backs up and retains backups for those resources according to the backup plan. You can create multiple backup plans if you have workloads with different backup requirements.

This module provides ready-made backup plans (similar to the console experience):

# Example automatically generated without compilation. See
import aws_cdk.aws_backup as backup

# Daily, weekly and monthly with 5 year retention
plan = backup.BackupPlan.daily_weekly_monthly5_year_retention(self, "Plan")

Assigning resources to a plan can be done with addSelection():

# Example automatically generated without compilation. See
        backup.BackupResource.from_dynamo_db_table(my_table), # A DynamoDB table
        backup.BackupResource.from_tag("stage", "prod"), # All resources that are tagged stage=prod in the region/account

If not specified, a new IAM role with a managed policy for backup will be created for the selection. The BackupSelection implements IGrantable.

To add rules to a plan, use addRule():

# Example automatically generated without compilation. See
    schedule_expression=events.Schedule.cron(# Only cron expressions are supported

Ready-made rules are also available:

# Example automatically generated without compilation. See

By default a new vault is created when creating a plan. It is also possible to specify a vault either at the plan level or at the rule level.

# Example automatically generated without compilation. See
plan = backup.BackupPlan.daily35_day_retention(self, "Plan", my_vault)# Use `myVault` for all plan rules

Backup vault

In AWS Backup, a backup vault is a container that you organize your backups in. You can use backup vaults to set the AWS Key Management Service (AWS KMS) encryption key that is used to encrypt backups in the backup vault and to control access to the backups in the backup vault. If you require different encryption keys or access policies for different groups of backups, you can optionally create multiple backup vaults.

# Example automatically generated without compilation. See
vault = BackupVault(stack, "Vault",
    encryption_key=my_key, # Custom encryption key

A vault has a default RemovalPolicy set to RETAIN. Note that removing a vault that contains recovery points will fail.
