# RestoreDBClusterFromSnapshot
Creates a new DB cluster from a DB snapshot or DB cluster snapshot.
If a DB snapshot is specified, the target DB cluster is created from the source DB snapshot with a default configuration and default security group.
If a DB cluster snapshot is specified, the target DB cluster is created from the source DB cluster restore point with the same configuration as the original source DB cluster, except that the new DB cluster is created with the default security group.
## Request Parameters
For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).
**AvailabilityZones.AvailabilityZone.N**
Provides the list of EC2 Availability Zones that instances in the restored DB cluster can be created in.
Type: Array of strings
Required: No
** CopyTagsToSnapshot **
*If set to `true`, tags are copied to any snapshot of the restored DB cluster that is created.*
Type: Boolean
Required: No
** DatabaseName **
Not supported.
Type: String
Required: No
** DBClusterIdentifier **
The name of the DB cluster to create from the DB snapshot or DB cluster snapshot. This parameter isn't case-sensitive.
Constraints:
+ Must contain from 1 to 63 letters, numbers, or hyphens
+ First character must be a letter
+ Cannot end with a hyphen or contain two consecutive hyphens
Example: `my-snapshot-id`
Type: String
Required: Yes
** DBClusterParameterGroupName **
The name of the DB cluster parameter group to associate with the new DB cluster.
Constraints:
+ If supplied, must match the name of an existing DBClusterParameterGroup.
Type: String
Required: No
** DBSubnetGroupName **
The name of the DB subnet group to use for the new DB cluster.
Constraints: If supplied, must match the name of an existing DBSubnetGroup.
Example: `mySubnetgroup`
Type: String
Required: No
** DeletionProtection **
A value that indicates whether the DB cluster has deletion protection enabled. The database can't be deleted when deletion protection is enabled. By default, deletion protection is disabled.
Type: Boolean
Required: No
**EnableCloudwatchLogsExports.member.N**
The list of logs that the restored DB cluster is to export to Amazon CloudWatch Logs.
Type: Array of strings
Required: No
** EnableIAMDatabaseAuthentication **
True to enable mapping of Amazon Identity and Access Management (IAM) accounts to database accounts, and otherwise false.
Default: `false`
Type: Boolean
Required: No
** Engine **
The database engine to use for the new DB cluster.
Default: The same as source
Constraint: Must be compatible with the engine of the source
Type: String
Required: Yes
** EngineVersion **
The version of the database engine to use for the new DB cluster.
Type: String
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 KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are restoring a DB cluster with the same Amazon account that owns the KMS encryption key used to encrypt the new DB cluster, then you can use the KMS key alias instead of the ARN for the KMS encryption key.
If you do not specify a value for the `KmsKeyId` parameter, then the following will occur:
+ 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` is not encrypted, then the restored DB cluster is not encrypted.
Type: String
Required: No
** OptionGroupName **
*(Not supported by Neptune)*
Type: String
Required: No
** Port **
The port number on which the new DB cluster accepts connections.
Constraints: Value must be `1150-65535`
Default: The same port as the original DB cluster.
Type: Integer
Required: No
** ServerlessV2ScalingConfiguration **
Contains the scaling configuration of a Neptune Serverless DB cluster.
For more information, see [Using Amazon Neptune Serverless](https://docs.aws.amazon.com/neptune/latest/userguide/neptune-serverless-using.html) in the *Amazon Neptune User Guide*.
Type: [ServerlessV2ScalingConfiguration](API_ServerlessV2ScalingConfiguration.md) object
Required: No
** SnapshotIdentifier **
The identifier for the DB snapshot or DB cluster snapshot to restore from.
You can use either the name or the Amazon Resource Name (ARN) to specify a DB cluster snapshot. However, you can use only the ARN to specify a DB snapshot.
Constraints:
+ Must match the identifier of an existing Snapshot.
Type: String
Required: Yes
** StorageType **
Specifies the storage type to be associated with the DB cluster.
Valid values: `standard`, `iopt1`
Default: `standard`
Type: String
Required: No
**Tags.Tag.N**
The tags to be assigned to the restored DB cluster.
Type: Array of [Tag](API_Tag.md) objects
Required: No
**VpcSecurityGroupIds.VpcSecurityGroupId.N**
A list of VPC security groups that the new DB cluster will belong to.
Type: Array of strings
Required: No
## Response Elements
The following element is returned by the service.
** DBCluster **
Contains the details of an Amazon Neptune DB cluster.
This data type is used as a response element in the [DescribeDBClusters](API_DescribeDBClusters.md).
Type: [DBCluster](API_DBCluster.md) object
## Errors
For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md).
** DBClusterAlreadyExistsFault **
User already has a DB cluster with the given identifier.
HTTP Status Code: 400
** DBClusterParameterGroupNotFound **
*DBClusterParameterGroupName* does not refer to an existing DB Cluster parameter group.
HTTP Status Code: 404
** DBClusterQuotaExceededFault **
User attempted to create a new DB cluster and the user has already reached the maximum allowed DB cluster quota.
HTTP Status Code: 403
** DBClusterSnapshotNotFoundFault **
*DBClusterSnapshotIdentifier* does not refer to an existing DB cluster snapshot.
HTTP Status Code: 404
** DBSnapshotNotFound **
*DBSnapshotIdentifier* does not refer to an existing DB snapshot.
HTTP Status Code: 404
