#copy(options = {}) ⇒ DBSnapshot

Examples:

Request syntax with placeholder values


dbsnapshot = db_snapshot.copy({
  target_db_snapshot_identifier: "String", # required
  kms_key_id: "String",
  tags: [
    {
      key: "String",
      value: "String",
    },
  ],
  copy_tags: false,
  pre_signed_url: "String",
  option_group_name: "String",
  target_custom_availability_zone: "String",
  copy_option_group: false,
  source_region: "String",
})

Parameters:

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :target_db_snapshot_identifier (required, String) —

    The identifier for the copy of the snapshot.

    Constraints:

    • Can't be null, empty, or blank

    • Must contain from 1 to 255 letters, numbers, or hyphens

    • First character must be a letter

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

    Example: my-db-snapshot

  • :kms_key_id (String) —

    The Amazon Web Services KMS key identifier for an encrypted DB snapshot. The Amazon Web Services KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key.

    If you copy an encrypted DB snapshot from your Amazon Web Services account, you can specify a value for this parameter to encrypt the copy with a new KMS key. If you don't specify a value for this parameter, then the copy of the DB snapshot is encrypted with the same Amazon Web Services KMS key as the source DB snapshot.

    If you copy an encrypted DB snapshot that is shared from another Amazon Web Services account, then you must specify a value for this parameter.

    If you specify this parameter when you copy an unencrypted snapshot, the copy is encrypted.

    If you copy an encrypted snapshot to a different Amazon Web Services Region, then you must specify an Amazon Web Services KMS key identifier for the destination Amazon Web Services Region. KMS keys are specific to the Amazon Web Services Region that they are created in, and you can't use KMS keys from one Amazon Web Services Region in another Amazon Web Services Region.

  • :tags (Array<Types::Tag>) —

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

  • :copy_tags (Boolean) —

    A value that indicates whether to copy all tags from the source DB snapshot to the target DB snapshot. By default, tags aren't copied.

  • :pre_signed_url (String) —

    When you are copying a snapshot from one Amazon Web Services GovCloud (US) Region to another, the URL that contains a Signature Version 4 signed request for the CopyDBSnapshot API operation in the source Amazon Web Services Region that contains the source DB snapshot to copy.

    This setting applies only to Amazon Web Services GovCloud (US) Regions. It's ignored in other Amazon Web Services Regions.

    You must specify this parameter when you copy an encrypted DB snapshot from another Amazon Web Services Region by using the Amazon RDS API. Don't specify PreSignedUrl when you are copying an encrypted DB snapshot in the same Amazon Web Services Region.

    The presigned URL must be a valid request for the CopyDBClusterSnapshot API operation that can run in the source Amazon Web Services Region that contains the encrypted DB cluster snapshot to copy. The presigned URL request must contain the following parameter values:

    • DestinationRegion - The Amazon Web Services Region that the encrypted DB snapshot is copied to. This Amazon Web Services Region is the same one where the CopyDBSnapshot operation is called that contains this presigned URL.

      For example, if you copy an encrypted DB snapshot from the us-west-2 Amazon Web Services Region to the us-east-1 Amazon Web Services Region, then you call the CopyDBSnapshot operation in the us-east-1 Amazon Web Services Region and provide a presigned URL that contains a call to the CopyDBSnapshot operation in the us-west-2 Amazon Web Services Region. For this example, the DestinationRegion in the presigned URL must be set to the us-east-1 Amazon Web Services Region.

    • KmsKeyId - The KMS key identifier for the KMS key to use to encrypt the copy of the DB snapshot in the destination Amazon Web Services Region. This is the same identifier for both the CopyDBSnapshot operation that is called in the destination Amazon Web Services Region, and the operation contained in the presigned URL.

    • SourceDBSnapshotIdentifier - The DB snapshot identifier for the encrypted snapshot to be copied. This identifier must be in the Amazon Resource Name (ARN) format for the source Amazon Web Services Region. For example, if you are copying an encrypted DB snapshot from the us-west-2 Amazon Web Services Region, then your SourceDBSnapshotIdentifier looks like the following example: arn:aws:rds:us-west-2:123456789012:snapshot:mysql-instance1-snapshot-20161115.

    To learn how to generate a Signature Version 4 signed request, see Authenticating Requests: Using Query Parameters (Amazon Web Services Signature Version 4) and Signature Version 4 Signing Process.

    If you are using an Amazon Web Services SDK tool or the CLI, you can specify SourceRegion (or --source-region for the CLI) instead of specifying PreSignedUrl manually. Specifying SourceRegion autogenerates a presigned URL that is a valid request for the operation that can run in the source Amazon Web Services Region.

  • :option_group_name (String) —

    The name of an option group to associate with the copy of the snapshot.

    Specify this option if you are copying a snapshot from one Amazon Web Services Region to another, and your DB instance uses a nondefault option group. If your source DB instance uses Transparent Data Encryption for Oracle or Microsoft SQL Server, you must specify this option when copying across Amazon Web Services Regions. For more information, see Option group considerations in the Amazon RDS User Guide.

  • :target_custom_availability_zone (String) —

    The external custom Availability Zone (CAZ) identifier for the target CAZ.

    Example: rds-caz-aiqhTgQv.

  • :copy_option_group (Boolean) —

    A value that indicates whether to copy the DB option group associated with the source DB snapshot to the target Amazon Web Services account and associate with the target DB snapshot. The associated option group can be copied only with cross-account snapshot copy calls.

  • :source_region (String) —

    The source region of the snapshot. This is only needed when the shapshot is encrypted and in a different region.

    Example: us-east-1a

  • :db_subnet_group_name (String) —

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

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

    Example: mydbsubnetgroup

  • :multi_az (Boolean) —

    A value that indicates whether the DB instance is a Multi-AZ deployment.

    Constraint: You can't specify the AvailabilityZone parameter if the DB instance is a Multi-AZ deployment.

  • :publicly_accessible (Boolean) —

    A value that indicates whether the DB instance is publicly accessible.

    When the DB instance is publicly accessible, its Domain Name System (DNS) endpoint resolves to the private IP address from within the DB instance's virtual private cloud (VPC). It resolves to the public IP address from outside of the DB instance's VPC. Access to the DB instance is ultimately controlled by the security group it uses. That public access is not permitted if the security group assigned to the DB instance doesn't permit it.

    When the DB instance isn't publicly accessible, it is an internal DB instance with a DNS name that resolves to a private IP address.

    For more information, see CreateDBInstance.

  • :iops (Integer) —

    Specifies the amount of provisioned IOPS for the DB instance, expressed in I/O operations per second. If this parameter isn't specified, the IOPS value is taken from the backup. If this parameter is set to 0, the new instance is converted to a non-PIOPS instance. The conversion takes additional time, though your DB instance is available for connections before the conversion starts.

    The provisioned IOPS value must follow the requirements for your database engine. For more information, see Amazon RDS Provisioned IOPS storage in the Amazon RDS User Guide.

    Constraints: Must be an integer greater than 1000.

    This setting doesn't apply to RDS Custom.

  • :copy_tags_to_snapshot (Boolean) —

    A value that indicates whether to copy all tags from the restored DB instance to snapshots of the DB instance.

    In most cases, tags aren't copied by default. However, when you restore a DB instance from a DB snapshot, RDS checks whether you specify new tags. If yes, the new tags are added to the restored DB instance. If there are no new tags, RDS looks for the tags from the source DB instance for the DB snapshot, and then adds those tags to the restored DB instance.

    For more information, see Copying tags to DB instance snapshots in the Amazon RDS 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.

    This setting doesn't apply to RDS Custom.

  • :enable_iam_database_authentication (Boolean) —

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

    For more information about IAM database authentication, see IAM Database Authentication for MySQL and PostgreSQL in the Amazon RDS User Guide.

    This setting doesn't apply to RDS Custom.

  • :enable_cloudwatch_logs_exports (Array<String>) —

    The list of logs that the restored DB instance is to export to CloudWatch Logs. The values in the list depend on the DB engine being used. For more information, see Publishing Database Logs to Amazon CloudWatch Logs in the Amazon RDS User Guide.

    A value that indicates whether to enable a customer-owned IP address (CoIP) for an RDS on Outposts DB instance.

    A CoIP provides local or external connectivity to resources in your Outpost subnets through your on-premises network. For some use cases, a CoIP can provide lower latency for connections to the DB instance from outside of its virtual private cloud (VPC) on your local network.

    This setting doesn't apply to RDS Custom.

    For more information about RDS on Outposts, see Working with Amazon RDS on Amazon Web Services Outposts in the Amazon RDS User Guide.

    For more information about CoIPs, see Customer-owned IP addresses in the Amazon Web Services Outposts User Guide.

  • :custom_iam_instance_profile (String) —

#wait_until(options = {}) {|resource| ... } ⇒ Resource

Deprecated.

Use [Aws::RDS::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged.

Waiter polls an API operation until a resource enters a desired state.

Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

Example

instance.wait_until(max_attempts:10, delay:5) do |instance|
  instance.state.name == 'running'
end

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

begin
  resource.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :max_attempts (Integer) — default: 10 —

    Maximum number of

  • :delay (Integer) — default: 10 —

    Delay between each

  • :before_attempt (Proc) — default: nil —

    Callback

  • :before_wait (Proc) — default: nil —

    Callback

Yield Parameters:

  • resource (Resource) —

    to be used in the waiting condition.

Returns:

  • (Resource) —

    if the waiter was successful

Raises:

  • (Aws::Waiters::Errors::FailureStateError) —

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

    yet successful.

  • (Aws::Waiters::Errors::UnexpectedError) —

    Raised when an error is encountered while polling for a resource that is not expected.

  • (NotImplementedError) —

    Raised when the resource does not
