RestoreDBClusterFromSnapshot - Amazon Relational Database Service
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

RestoreDBClusterFromSnapshot

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.

Note

This action only restores the DB cluster, not the DB instances for that DB cluster. You must invoke the CreateDBInstance action 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 RestoreDBClusterFromSnapshot action 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 deployments with two readable standby DB instances in the Amazon RDS User Guide.

See MySQL on Amazon RDS Versions in the Amazon RDS User Guide.

PostgreSQL

See Amazon RDS for PostgreSQL versions and extensions in the Amazon RDS User Guide.

Required: No

Iops

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

Type: Integer

Required: No

KmsKeyId

The Amazon KMS key identifier to use when restoring an encrypted DB cluster from a DB snapshot or DB cluster snapshot.

The Amazon KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key. To use a KMS key in a different Amazon Web Services account, specify the key ARN or alias ARN.

When you don't specify a value for the KmsKeyId parameter, then the following occurs:

  • If the DB snapshot or DB cluster snapshot in SnapshotIdentifier is encrypted, then the restored DB cluster is encrypted using the KMS key that was used to encrypt the DB snapshot or DB cluster snapshot.

  • If the DB snapshot or DB cluster snapshot in SnapshotIdentifier isn't encrypted, then the restored DB cluster isn't encrypted.

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

Type: String

Required: No

NetworkType

The network type of the DB cluster.

  • 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

Type: String

Required: No

OptionGroupName

The name of the option group to use for the restored DB cluster.

DB clusters are associated with a default option group that can't be modified.

Type: String

Default: The same port as the original DB cluster.

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

Type: Integer

Required: No

PubliclyAccessible

A value that indicates 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.
