restore-db-cluster-to-point-in-time¶

Description¶

Restores a DB cluster to an arbitrary point in time. Users can restore to any point in time before LatestRestorableTime for up to BackupRetentionPeriod days. The target DB cluster is created from the source DB cluster with the same configuration as the original DB cluster, except that the new DB cluster is created with the default DB 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 RestoreDBClusterToPointInTime action has completed and the DB cluster is available.

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

--restore-type (string)

The type of restore to be performed. You can specify one of the following values:

full-copy - The new DB cluster is restored as a full copy of the source DB cluster.

copy-on-write - The new DB cluster is restored as a clone of the source DB cluster.

If you don’t specify a RestoreType value, then the new DB cluster is restored as a full copy of the source DB cluster.

--source-db-cluster-identifier (string)

The identifier of the source DB cluster from which to restore.

Constraints:

Must match the identifier of an existing DBCluster.

--restore-to-time (timestamp)

The date and time to restore the DB cluster to.

Valid Values: Value must be a time in Universal Coordinated Time (UTC) format

Constraints:

Must be before the latest restorable time for the DB instance

Must be specified if UseLatestRestorableTime parameter is not provided

Cannot be specified if UseLatestRestorableTime parameter is true

Cannot be specified if RestoreType parameter is copy-on-write

Example: 2015-03-07T23:45:00Z

--use-latest-restorable-time | --no-use-latest-restorable-time (boolean)

A value that is set to true to restore the DB cluster to the latest restorable backup time, and false otherwise.

Default: false

Constraints: Cannot be specified if RestoreToTime parameter is provided.

--port (integer)

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.

--db-subnet-group-name (string)

The DB subnet group name to use for the new DB cluster.

Constraints: If supplied, must match the name of an existing DBSubnetGroup.

Example: mySubnetgroup

--option-group-name (string)

(Not supported by Neptune)

--vpc-security-group-ids (list)

A list of VPC security groups that the new DB cluster belongs to.

(string)

Syntax:

"string" "string" ...

--tags (list)

The tags to be applied to the restored DB cluster.

(structure)

Metadata assigned to an Amazon Neptune resource consisting of a key-value pair.

Key -> (string)

A key is the required name of the tag. The string value can be from 1 to 128 Unicode characters in length and can’t be prefixed with “aws:” or “rds:”. The string can only contain only the set of Unicode letters, digits, white-space, ‘_’, ‘.’, ‘/’, ‘=’, ‘+’, ‘-‘ (Java regex: “^([\p{L}\p{Z}\p{N}_.:/=+-]*)$”).

Value -> (string)

A value is the optional value of the tag. The string value can be from 1 to 256 Unicode characters in length and can’t be prefixed with “aws:” or “rds:”. The string can only contain only the set of Unicode letters, digits, white-space, ‘_’, ‘.’, ‘/’, ‘=’, ‘+’, ‘-‘ (Java regex: “^([\p{L}\p{Z}\p{N}_.:/=+-]*)$”).

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Value": "string"
  }
  ...
]

--kms-key-id (string)

The AWS KMS key identifier to use when restoring an encrypted DB cluster from an encrypted DB cluster.

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 AWS 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.

You can restore to a new DB cluster and encrypt the new DB cluster with a KMS key that is different than the KMS key used to encrypt the source DB cluster. The new DB cluster is encrypted with the KMS key identified by the KmsKeyId parameter.

If you do not specify a value for the KmsKeyId parameter, then the following will occur:

If the DB cluster is encrypted, then the restored DB cluster is encrypted using the KMS key that was used to encrypt the source DB cluster.

If the DB cluster is not encrypted, then the restored DB cluster is not encrypted.

If DBClusterIdentifier refers to a DB cluster that is not encrypted, then the restore request is rejected.

--enable-iam-database-authentication | --no-enable-iam-database-authentication (boolean)

True to enable mapping of AWS Identity and Access Management (IAM) accounts to database accounts, and otherwise false.

Default: false

--enable-cloudwatch-logs-exports (list)

The list of logs that the restored DB cluster is to export to CloudWatch Logs.

(string)

Syntax:

"string" "string" ...

--db-cluster-parameter-group-name (string)

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.

--deletion-protection | --no-deletion-protection (boolean)

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.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Output¶

DBCluster -> (structure)

Contains the details of an Amazon Neptune DB cluster.

This data type is used as a response element in the DescribeDBClusters action.

AllocatedStorage -> (integer)

AllocatedStorage always returns 1, because Neptune DB cluster storage size is not fixed, but instead automatically adjusts as needed.

AvailabilityZones -> (list)

Provides the list of EC2 Availability Zones that instances in the DB cluster can be created in.

(string)

BackupRetentionPeriod -> (integer)

Specifies the number of days for which automatic DB snapshots are retained.

CharacterSetName -> (string)

(Not supported by Neptune)

DatabaseName -> (string)

Contains the name of the initial database of this DB cluster that was provided at create time, if one was specified when the DB cluster was created. This same name is returned for the life of the DB cluster.

DBClusterIdentifier -> (string)

Contains a user-supplied DB cluster identifier. This identifier is the unique key that identifies a DB cluster.

DBClusterParameterGroup -> (string)

Specifies the name of the DB cluster parameter group for the DB cluster.
