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.

For more information on Amazon Aurora, see What Is Amazon Aurora? in the Amazon Aurora User Guide.

Note

This action only applies to Aurora DB clusters.

A list of tags. For more information, see Tagging Amazon RDS Resources in the Amazon RDS User Guide.

(structure)

Metadata assigned to an Amazon RDS 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}_.:/=+-@]*)$”).

--kms-key-id (string)

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

The AWS KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the AWS KMS customer master key (CMK). To use a CMK in a different AWS account, specify the key ARN or alias ARN.

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

If you don’t specify a value for the KmsKeyId parameter, then the following occurs:

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

  • If the DB cluster isn’t encrypted, then the restored DB cluster isn’t encrypted.

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

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

A value that indicates whether to enable mapping of AWS Identity and Access Management (IAM) accounts to database accounts. By default, mapping is disabled.

For more information, see IAM Database Authentication in the Amazon Aurora User Guide.

--backtrack-window (long)

The target backtrack window, in seconds. To disable backtracking, set this value to 0.

Note

Currently, Backtrack is only supported for Aurora MySQL DB clusters.

  • Must be 1 to 255 letters, numbers, or hyphens.

  • First character must be a letter.

  • Can’t end with a hyphen or contain two consecutive hyphens.

--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.

--copy-tags-to-snapshot | --no-copy-tags-to-snapshot (boolean)

A value that indicates whether to copy all tags from the restored DB cluster to snapshots of the restored DB cluster. The default is not to copy them.

--domain (string)

Specify the Active Directory directory ID to restore the DB cluster in. The domain must be created prior to this operation.

For Amazon Aurora DB clusters, Amazon RDS can use Kerberos Authentication to authenticate users that connect to the DB cluster. For more information, see Kerberos Authentication in the Amazon Aurora User Guide .

--domain-iam-role-name (string)

Specify the name of the IAM role to be used when making API calls to the Directory Service.

--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 a DB cluster to a specified time

The following restore-db-cluster-to-point-in-time example restores the DB cluster named database-4 to the latest possible time. Using copy-on-write as the restore type restores the new DB cluster as a clone of the source DB cluster.

aws rds restore-db-cluster-to-point-in-time \
    --source-db-cluster-identifier database-4 \
    --db-cluster-identifier sample-cluster-clone \
    --restore-type copy-on-write \
