AWS Backup Construct Library
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):
// Daily, weekly and monthly with 5 year retention BackupPlan plan = BackupPlan.dailyWeeklyMonthly5YearRetention(this, "Plan");
Assigning resources to a plan can be done with addSelection()
:
BackupPlan plan; Vpc vpc; ITable myTable = Table.fromTableName(this, "Table", "myTableName"); DatabaseInstance myDatabaseInstance = DatabaseInstance.Builder.create(this, "DatabaseInstance") .engine(DatabaseInstanceEngine.mysql(MySqlInstanceEngineProps.builder().version(MysqlEngineVersion.VER_8_0_26).build())) .vpc(vpc) .build(); DatabaseCluster myDatabaseCluster = DatabaseCluster.Builder.create(this, "DatabaseCluster") .engine(DatabaseClusterEngine.auroraMysql(AuroraMysqlClusterEngineProps.builder().version(AuroraMysqlEngineVersion.VER_2_08_1).build())) .credentials(Credentials.fromGeneratedSecret("clusteradmin")) .instanceProps(InstanceProps.builder() .vpc(vpc) .build()) .build(); ServerlessCluster myServerlessCluster = ServerlessCluster.Builder.create(this, "ServerlessCluster") .engine(DatabaseClusterEngine.AURORA_POSTGRESQL) .parameterGroup(ParameterGroup.fromParameterGroupName(this, "ParameterGroup", "default.aurora-postgresql11")) .vpc(vpc) .build(); Construct myCoolConstruct = new Construct(this, "MyCoolConstruct"); plan.addSelection("Selection", BackupSelectionOptions.builder() .resources(List.of(BackupResource.fromDynamoDbTable(myTable), BackupResource.fromRdsDatabaseInstance(myDatabaseInstance), BackupResource.fromRdsDatabaseCluster(myDatabaseCluster), BackupResource.fromRdsServerlessCluster(myServerlessCluster), BackupResource.fromTag("stage", "prod"), BackupResource.fromConstruct(myCoolConstruct))) .build());
If not specified, a new IAM role with a managed policy for backup will be
created for the selection. The BackupSelection
implements IGrantable
.
To disable the plan from assigning the default AWSBackupServiceRolePolicyForBackup
backup policy use the disableDefaultBackupPolicy
property.
This is useful if you want to avoid granting unnecessary permissions to the role.
BackupPlan plan; Role role = Role.Builder.create(this, "BackupRole") .assumedBy(new ServicePrincipal("backup.amazonaws.com")) .build(); // Assign S3-specific backup policy role.addManagedPolicy(ManagedPolicy.fromAwsManagedPolicyName("AWSBackupServiceRolePolicyForS3Backup")); plan.addSelection("Selection", BackupSelectionOptions.builder() .resources(List.of(BackupResource.fromTag("stage", "prod"))) .role(role) .disableDefaultBackupPolicy(true) .build());
To add rules to a plan, use addRule()
:
BackupPlan plan; plan.addRule(BackupPlanRule.Builder.create() .completionWindow(Duration.hours(2)) .startWindow(Duration.hours(1)) .scheduleExpression(Schedule.cron(CronOptions.builder() // Only cron expressions are supported .day("15") .hour("3") .minute("30").build())) .moveToColdStorageAfter(Duration.days(30)) .build());
Continuous backup and point-in-time restores (PITR) can be configured.
Property deleteAfter
defines the retention period for the backup. It is mandatory if PITR is enabled.
If no value is specified, the retention period is set to 35 days which is the maximum retention period supported by PITR.
Property moveToColdStorageAfter
must not be specified because PITR does not support this option.
This example defines an AWS Backup rule with PITR and a retention period set to 14 days:
BackupPlan plan; plan.addRule(BackupPlanRule.Builder.create() .enableContinuousBackup(true) .deleteAfter(Duration.days(14)) .build());
Rules can also specify to copy recovery points to another Backup Vault using copyActions
. Copied recovery points can
optionally have moveToColdStorageAfter
and deleteAfter
configured.
BackupPlan plan; BackupVault secondaryVault; plan.addRule(BackupPlanRule.Builder.create() .copyActions(List.of(BackupPlanCopyActionProps.builder() .destinationBackupVault(secondaryVault) .moveToColdStorageAfter(Duration.days(30)) .deleteAfter(Duration.days(120)) .build())) .build());
You can assign your own metadata to the resources that are associated with the rule when restored from backup using recoveryPointTags
. Each tag is a key-value pair.
BackupPlan plan; plan.addRule(BackupPlanRule.Builder.create() .recoveryPointTags(Map.of( "key", "value")) .build());
Ready-made rules are also available:
BackupPlan plan; plan.addRule(BackupPlanRule.daily()); plan.addRule(BackupPlanRule.weekly());
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.
IBackupVault myVault = BackupVault.fromBackupVaultName(this, "Vault1", "myVault"); IBackupVault otherVault = BackupVault.fromBackupVaultName(this, "Vault2", "otherVault"); BackupPlan plan = BackupPlan.daily35DayRetention(this, "Plan", myVault); // Use `myVault` for all plan rules plan.addRule(BackupPlanRule.monthly1Year(otherVault));
You can backup
VSS-enabled Windows applications running on Amazon EC2 instances by setting the windowsVss
parameter to true
. If the application has VSS writer registered with Windows VSS,
then AWS Backup creates a snapshot that will be consistent for that application.
BackupPlan plan = BackupPlan.Builder.create(this, "Plan") .windowsVss(true) .build();
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.
IKey myKey = Key.fromKeyArn(this, "MyKey", "aaa"); ITopic myTopic = Topic.fromTopicArn(this, "MyTopic", "bbb"); BackupVault vault = BackupVault.Builder.create(this, "Vault") .encryptionKey(myKey) // Custom encryption key .notificationTopic(myTopic) .build();
A vault has a default RemovalPolicy
set to RETAIN
. Note that removing a vault
that contains recovery points will fail.
You can assign policies to backup vaults and the resources they contain. Assigning policies allows you to do things like grant access to users to create backup plans and on-demand backups, but limit their ability to delete recovery points after they're created.
Use the accessPolicy
property to create a backup vault policy:
BackupVault vault = BackupVault.Builder.create(this, "Vault") .accessPolicy(PolicyDocument.Builder.create() .statements(List.of( PolicyStatement.Builder.create() .effect(Effect.DENY) .principals(List.of(new AnyPrincipal())) .actions(List.of("backup:DeleteRecoveryPoint")) .resources(List.of("*")) .conditions(Map.of( "StringNotLike", Map.of( "aws:userId", List.of("user1", "user2")))) .build())) .build()) .build();
Alternativately statements can be added to the vault policy using addToAccessPolicy()
.
Use the blockRecoveryPointDeletion
property or the blockRecoveryPointDeletion()
method to add
a statement to the vault access policy that prevents recovery point deletions in your vault:
BackupVault backupVault; BackupVault.Builder.create(this, "Vault") .blockRecoveryPointDeletion(true) .build(); backupVault.blockRecoveryPointDeletion();
By default access is not restricted.
Use the lockConfiguration
property to enable AWS Backup Vault Lock:
BackupVault.Builder.create(this, "Vault") .lockConfiguration(LockConfiguration.builder() .minRetention(Duration.days(30)) .build()) .build();
Importing existing backup vault
To import an existing backup vault into your CDK application, use the BackupVault.fromBackupVaultArn
or BackupVault.fromBackupVaultName
static method. Here is an example of giving an IAM Role permission to start a backup job:
IBackupVault importedVault = BackupVault.fromBackupVaultName(this, "Vault", "myVaultName"); Role role = Role.Builder.create(this, "Access Role").assumedBy(new ServicePrincipal("lambda.amazonaws.com")).build(); importedVault.grant(role, "backup:StartBackupJob");
