Restore Db Cluster from Snapshot

rds_restore_db_cluster_from_snapshot R Documentation

Creates a new DB cluster from a DB snapshot or DB cluster snapshot

Description

Creates a new DB cluster from a DB snapshot or DB cluster snapshot.

The target DB cluster is created from the source snapshot with a default configuration. If you don't specify a security group, the new DB cluster is associated with the default security group.

This operation only restores the DB cluster, not the DB instances for that DB cluster. You must invoke the create_db_instance operation to create DB instances for the restored DB cluster, specifying the identifier of the restored DB cluster in DBClusterIdentifier. You can create DB instances only after the restore_db_cluster_from_snapshot operation has completed and the DB cluster is available.

For more information on Amazon Aurora DB clusters, see What is Amazon Aurora? in the Amazon Aurora User Guide.

For more information on Multi-AZ DB clusters, see Multi-AZ DB cluster deployments in the Amazon RDS User Guide.

For DB clusters in serverless DB engine mode, the scaling properties of the DB cluster.

Valid for: Aurora DB clusters only

DBClusterParameterGroupName

The name of the DB cluster parameter group to associate with this DB cluster. If this argument is omitted, the default DB cluster parameter group for the specified engine is used.

Constraints:

  • If supplied, must match the name of an existing default DB cluster parameter group.

  • Must be 1 to 255 letters, numbers, or hyphens.

  • First character must be a letter.

  • Can't end with a hyphen or contain two consecutive hyphens.

For more information, see Kerberos Authentication in the Amazon RDS User Guide.

Valid for: Aurora DB clusters only

DomainIAMRoleName

The name of the IAM role to be used when making API calls to the Directory Service.

Valid for: Aurora DB clusters only

DBClusterInstanceClass

The compute and memory capacity of the each DB instance in the Multi-AZ DB cluster, for example db.m6gd.xlarge. Not all DB instance classes are available in all Amazon Web Services Regions, or for all database engines.

For the full list of DB instance classes, and availability for your engine, see DB Instance Class in the Amazon RDS User Guide.

Valid for: Multi-AZ DB clusters only

StorageType

Specifies the storage type to be associated with the DB cluster.

When specified for a Multi-AZ DB cluster, a value for the Iops parameter is required.

For information about valid IOPS values, see Amazon RDS Provisioned IOPS storage in the Amazon RDS User Guide.

Constraints: Must be a multiple between .5 and 50 of the storage amount for the DB instance.

Valid for: Aurora DB clusters and Multi-AZ DB clusters

PubliclyAccessible

Specifies whether the DB cluster is publicly accessible.

When the DB cluster is publicly accessible, its Domain Name System (DNS) endpoint resolves to the private IP address from within the DB cluster's virtual private cloud (VPC). It resolves to the public IP address from outside of the DB cluster's VPC. Access to the DB cluster is ultimately controlled by the security group it uses. That public access is not permitted if the security group assigned to the DB cluster doesn't permit it.

When the DB cluster isn't publicly accessible, it is an internal DB cluster with a DNS name that resolves to a private IP address.

Default: The default behavior varies depending on whether DBSubnetGroupName is specified.

If DBSubnetGroupName isn't specified, and PubliclyAccessible isn't specified, the following applies:

  • If the default VPC in the target Region doesn’t have an internet gateway attached to it, the DB cluster is private.

  • If the default VPC in the target Region has an internet gateway attached to it, the DB cluster is public.

If DBSubnetGroupName is specified, and PubliclyAccessible isn't specified, the following applies:

  • If the subnets are part of a VPC that doesn’t have an internet gateway attached to it, the DB cluster is private.

  • If the subnets are part of a VPC that has an internet gateway attached to it, the DB cluster is public.

Valid for: Aurora DB clusters and Multi-AZ DB clusters

ServerlessV2ScalingConfiguration
NetworkType

The network type of the DB cluster.

Valid Values:

  • IPV4

  • DUAL

The network type is determined by the DBSubnetGroup specified for the DB cluster. A DBSubnetGroup can support only the IPv4 protocol or the IPv4 and the IPv6 protocols (DUAL).

For more information, see Working with a DB instance in a VPC in the Amazon Aurora User Guide.

Valid for: Aurora DB clusters only

RdsCustomClusterConfiguration

Reserved for future use.

EngineLifecycleSupport

The life cycle type for this DB cluster.

By default, this value is set to open-source-rds-extended-support, which enrolls your DB cluster into Amazon RDS Extended Support. At the end of standard support, you can avoid charges for Extended Support by setting the value to open-source-rds-extended-support-disabled. In this case, RDS automatically upgrades your restored DB cluster to a higher engine version, if the major engine version is past its end of standard support date.

You can use this setting to enroll your DB cluster into Amazon RDS Extended Support. With RDS Extended Support, you can run the selected major engine version on your DB cluster past the end of standard support for that engine version. For more information, see the following sections:

Valid for Cluster Type: Aurora DB clusters and Multi-AZ DB clusters

Valid Values: open-source-rds-extended-support | open-source-rds-extended-support-disabled

Default: open-source-rds-extended-support
