restore-db-cluster-from-snapshot

Description

Creates a new cluster from a snapshot or cluster snapshot.

If a snapshot is specified, the target cluster is created from the source DB snapshot with a default configuration and default security group.

If a cluster snapshot is specified, the target cluster is created from the source cluster restore point with the same configuration as the original source DB cluster, except that the new cluster is created with the default security group.

See ‘aws help’ for descriptions of global parameters.

Options

--availability-zones (list)

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

(string)

Syntax:

"string" "string" ...

--db-cluster-identifier (string)

The name of the cluster to create from the snapshot or cluster snapshot. This parameter isn’t case sensitive.

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.

Example: my-snapshot-id

--snapshot-identifier (string)

The identifier for the snapshot or cluster snapshot to restore from.

You can use either the name or the Amazon Resource Name (ARN) to specify a cluster snapshot. However, you can use only the ARN to specify a snapshot.

Constraints:

  • Must match the identifier of an existing snapshot.

--engine (string)

The database engine to use for the new cluster.

Default: The same as source.

Constraint: Must be compatible with the engine of the source.

--engine-version (string)

The version of the database engine to use for the new cluster.

--port (integer)

The port number on which the new cluster accepts connections.

Constraints: Must be a value from 1150 to 65535 .

Default: The same port as the original cluster.

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

The name of the subnet group 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 virtual private cloud (VPC) security groups that the new cluster will belong 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 AWS KMS key identifier to use when restoring an encrypted cluster from a DB snapshot or cluster snapshot.

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

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

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

  • If the snapshot or the cluster snapshot in SnapshotIdentifier is not encrypted, then the restored DB cluster is not encrypted.

--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.

--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.

See ‘aws help’ for descriptions of global parameters.

Examples

To restore an Amazon DocumentDB cluster from an automatic or manual snapshot

The following restore-db-cluster-from-snapshot example creates a new Amazon DocumentDB cluster named sample-cluster-2019-03-16-00-01-restored from the snapshot rds:sample-cluster-2019-03-16-00-01.

aws docdb restore-db-cluster-from-snapshot \
    --db-cluster-identifier sample-cluster-2019-03-16-00-01-restored \
    --engine docdb \
    --snapshot-identifier rds:sample-cluster-2019-03-16-00-01

Output

DBCluster -> (structure)

Detailed information about a cluster.

AvailabilityZones -> (list)

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

(string)

BackupRetentionPeriod -> (integer)

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

DBClusterIdentifier -> (string)

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

DBClusterParameterGroup -> (string)

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

DBSubnetGroup -> (string)

Specifies information on the subnet group that is associated with the cluster, including the name, description, and subnets in the subnet group.

Status -> (string)

Specifies the current state of this cluster.

PercentProgress -> (string)

Specifies the progress of the operation as a percentage.

EarliestRestorableTime -> (timestamp)

The earliest time to which a database can be restored with point-in-time restore.

Endpoint -> (string)

Specifies the connection endpoint for the primary instance of the cluster.

ReaderEndpoint -> (string)

The reader endpoint for the cluster. The reader endpoint for a cluster load balances connections across the Amazon DocumentDB replicas that are available in a cluster. As clients request new connections to the reader endpoint, Amazon DocumentDB distributes the connection requests among the Amazon DocumentDB replicas in the cluster. This functionality can help balance your read workload across multiple Amazon DocumentDB replicas in your cluster.

If a failover occurs, and the Amazon DocumentDB replica that you are connected to is promoted to be the primary instance, your connection is dropped. To continue sending your read workload to other Amazon DocumentDB replicas in the cluster, you can then reconnect to the reader endpoint.

MultiAZ -> (boolean)

Specifies whether the cluster has instances in multiple Availability Zones.

Engine -> (string)

Provides the name of the database engine to be used for this cluster.

EngineVersion -> (string)

Indicates the database engine version.

Specifies the port that the database engine is listening on.

MasterUsername -> (string)

Contains the master user name for the cluster.

PreferredBackupWindow -> (string)

Specifies the daily time range during which automated backups are created if automated backups are enabled, as determined by the BackupRetentionPeriod .

PreferredMaintenanceWindow -> (string)

Specifies the weekly time range during which system maintenance can occur, in Universal Coordinated Time (UTC).

  • PENDING - The IAM role ARN is being associated with the DB cluster.

  • INVALID - The IAM role ARN is associated with the cluster, but the cluster cannot assume the IAM role to access other AWS services on your behalf.

Specifies the time when the cluster was created, in Universal Coordinated Time (UTC).

EnabledCloudwatchLogsExports -> (list)

A list of log types that this cluster is configured to export to Amazon CloudWatch Logs.
