restore-db-cluster-to-point-in-time

Description

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

Options

--db-cluster-identifier (string)

The name of the new cluster to be created.

Constraints:

• Must contain from 1 to 63 letters, numbers, or hyphens.
• The 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.

Constraints: You can’t specify copy-on-write if the engine version of the source DB cluster is earlier than 1.11.

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 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 cluster to.

Valid values: A time in Universal Coordinated Time (UTC) format.

Constraints:

• Must be before the latest restorable time for the instance.
• Must be specified if the UseLatestRestorableTime parameter is not provided.
• Cannot be specified if the UseLatestRestorableTime parameter is true .
• Cannot be specified if the 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 cluster to the latest restorable backup time, and false otherwise.

Default: false

Constraints: Cannot be specified if the RestoreToTime parameter is provided.

--port (integer)

The port number on which the new cluster accepts connections.

Constraints: Must be a value from 1150 to 65535 .

Default: The default port for the engine.

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

The subnet group name to use for the new cluster.

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

Example: mySubnetgroup

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

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

(string)

Syntax:

"string" "string" ...

--tags (list)

The tags to be assigned to the restored cluster.

(structure)

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

Key -> (string)

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 contain only the set of Unicode letters, digits, white space, ‘_’, ‘.’, ‘/’, ‘=’, ‘+’, ‘-’ (Java regex: “^([\p{L}\p{Z}\p{N}_.:/=+-]*)$”).

Value -> (string)

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

The KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are restoring a cluster with the same Amazon Web Services account that owns the KMS encryption key used to encrypt the new cluster, then you can use the KMS key alias instead of the ARN for the KMS encryption key.

You can restore to a new cluster and encrypt the new cluster with an KMS key that is different from the KMS key used to encrypt the source 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 occurs:

• If the cluster is encrypted, then the restored cluster is encrypted using the KMS key that was used to encrypt the source cluster.
• If the cluster is not encrypted, then the restored cluster is not encrypted.

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

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

A list of log types that must be enabled for exporting to Amazon CloudWatch Logs.

(string)

Syntax:

"string" "string" ...

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

Specifies whether this cluster can be deleted. If DeletionProtection is enabled, the cluster cannot be deleted unless it is modified and DeletionProtection is disabled. DeletionProtection protects clusters from being accidentally deleted.

--storage-type (string)

The storage type to associate with the DB cluster.

For information on storage types for Amazon DocumentDB clusters, see Cluster storage configurations in the Amazon DocumentDB Developer Guide .

Valid values for storage type - standard | iopt1

Default value is standard

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

• json
• text
• table
• yaml
• yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

• on
• off
• auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

• base64
• raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To restore an Amazon DocumentDB cluster to a point-in-time from a manual snapshot
