restore-from-cluster-snapshot

Description

Creates a new cluster from a snapshot. By default, Amazon Redshift creates the resulting cluster with the same configuration as the original cluster from which the snapshot was created, except that the new cluster is created with the default cluster security and parameter groups. After Amazon Redshift creates the cluster, you can use the ModifyCluster API to associate a different security group and different parameter group with the restored cluster. If you are using a DS node type, you can also choose to change to another DS node type of the same size during restore.

If you restore a cluster into a VPC, you must provide a cluster subnet group where you want the cluster restored.

For more information about working with snapshots, go to Amazon Redshift Snapshots in the Amazon Redshift Cluster Management Guide .

Default: true

--cluster-subnet-group-name (string)

The name of the subnet group where you want to cluster restored.

A snapshot of cluster in VPC can be restored only in VPC. Therefore, you must provide subnet group name where you want the cluster restored.

--publicly-accessible | --no-publicly-accessible (boolean)

If true , the cluster can be accessed from a public network.

--owner-account (string)

The AWS customer account used to create or copy the snapshot. Required if you are restoring a snapshot you do not own, optional if you own the snapshot.

Specifies the name of the HSM client certificate the Amazon Redshift cluster uses to retrieve the data encryption keys stored in an HSM.

--hsm-configuration-identifier (string)

Specifies the name of the HSM configuration that contains the information the Amazon Redshift cluster can use to retrieve and store keys in an HSM.

--elastic-ip (string)

The elastic IP (EIP) address for the cluster.

The number of days that automated snapshots are retained. If the value is 0, automated snapshots are disabled. Even if automated snapshots are disabled, you can still create manual snapshots when you want with CreateClusterSnapshot .

Default: The value selected for the cluster from which the snapshot was taken.

Constraints: Must be a value from 0 to 35.

--manual-snapshot-retention-period (integer)

The default number of days to retain a manual snapshot. If the value is -1, the snapshot is retained indefinitely. This setting doesn’t change the retention period of existing snapshots.

In that case, you can choose to restore into another DS node type of the same size. For example, you can restore ds1.8xlarge into ds2.8xlarge, or ds1.xlarge into ds2.xlarge. If you have a DC instance type, you must restore into that same instance type and size. In other words, you can only restore a dc1.large instance type into another dc1.large instance type or dc2.large instance type. You can’t restore dc1.8xlarge to dc2.8xlarge. First restore to a dc1.8xlarge cluster, then resize to a dc2.8large cluster. For more information about node types, see About Clusters and Nodes in the Amazon Redshift Cluster Management Guide .

--enhanced-vpc-routing | --no-enhanced-vpc-routing (boolean)

Reserved.

--iam-roles (list)

A list of AWS Identity and Access Management (IAM) roles that can be used by the cluster to access other AWS services. You must supply the IAM roles in their Amazon Resource Name (ARN) format. You can supply up to 10 IAM roles in a single request.

A cluster can have up to 10 IAM roles associated at any time.

(string)

Syntax:

"string" "string" ...

--maintenance-track-name (string)

The name of the maintenance track for the restored cluster. When you take a snapshot, the snapshot inherits the MaintenanceTrack value from the cluster. The snapshot might be on a different track than the cluster that was the source for the snapshot. For example, suppose that you take a snapshot of a cluster that is on the current track and then change the cluster to be on the trailing track. In this case, the snapshot and the source cluster are on different tracks.

--snapshot-schedule-identifier (string)

A unique identifier for the snapshot schedule.

--number-of-nodes (integer)

The number of nodes specified when provisioning the restored cluster.

--availability-zone-relocation | --no-availability-zone-relocation (boolean)

The option to enable relocation for an Amazon Redshift cluster between Availability Zones after the cluster is restored.

--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.
