#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",
  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:

    • Cannot be null, empty, or blank

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

    • First character must be a letter

    • Cannot end with a hyphen or contain two consecutive hyphens

    Example: my-db-snapshot

  • :kms_key_id (String) —

    The AWS KMS key ID for an encrypted DB snapshot. The KMS key ID is the Amazon Resource Name (ARN), KMS key identifier, or the KMS key alias for the KMS encryption key.

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

    If you copy an encrypted DB snapshot that is shared from another AWS 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 AWS Region, then you must specify a KMS key for the destination AWS Region. KMS encryption keys are specific to the AWS Region that they are created in, and you can't use encryption keys from one AWS Region in another AWS Region.

  • :tags (Array<Types::Tag>) —

    A list of tags. For more information, see Tagging Amazon RDS Resources.

  • :copy_tags (Boolean) —

    True to copy all tags from the source DB snapshot to the target DB snapshot, and otherwise false. The default is false.

  • :pre_signed_url (String) —

    The URL that contains a Signature Version 4 signed request for the CopyDBSnapshot API action in the source AWS Region that contains the source DB snapshot to copy.

    You must specify this parameter when you copy an encrypted DB snapshot from another AWS Region by using the Amazon RDS API. You can specify the --source-region option instead of this parameter when you copy an encrypted DB snapshot from another AWS Region by using the AWS CLI.

    The presigned URL must be a valid request for the CopyDBSnapshot API action that can be executed in the source AWS Region that contains the encrypted DB snapshot to be copied. The presigned URL request must contain the following parameter values:

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

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

    • KmsKeyId - The AWS KMS key identifier for the key to use to encrypt the copy of the DB snapshot in the destination AWS Region. This is the same identifier for both the CopyDBSnapshot action that is called in the destination AWS Region, and the action 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 AWS Region. For example, if you are copying an encrypted DB snapshot from the us-west-2 AWS 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 (AWS Signature Version 4) and Signature Version 4 Signing Process.

  • :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 AWS 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 AWS Regions. For more information, see Option Group Considerations.

  • :destination_region (String)
  • :source_region (String) —

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

Returns:

    Constraints:

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

    • First character must be a letter

    • Cannot end with a hyphen or contain two consecutive hyphens

    Example: my-snapshot-id

  • :db_instance_class (String) —

    The compute and memory capacity of the Amazon RDS DB instance, for example, db.m4.large. Not all DB instance classes are available in all AWS Regions, or for all database engines. For the full list of DB instance classes, and availability for your engine, see DB Instance Class in the Amazon RDS User Guide.

    Default: The same DBInstanceClass as the original DB instance.

  • :port (Integer) —

    The port number on which the database accepts connections.

    Default: The same port as the original DB instance

    Constraints: Value must be 1150-65535

  • :availability_zone (String) —

    The EC2 Availability Zone that the DB instance is created in.

    Default: A random, system-chosen Availability Zone.

    Constraint: You can't specify the AvailabilityZone parameter if the MultiAZ parameter is set to true.

    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: mySubnetgroup

  • :multi_az (Boolean) —

    Specifies if the DB instance is a Multi-AZ deployment.

    Constraint: You can't specify the AvailabilityZone parameter if the MultiAZ parameter is set to true.

  • :publicly_accessible (Boolean) —

    Specifies the accessibility options for the DB instance. A value of true specifies an Internet-facing instance with a publicly resolvable DNS name, which resolves to a public IP address. A value of false specifies an internal instance with a DNS name that resolves to a private IP address.

    Default: The default behavior varies depending on whether a VPC has been requested or not. The following list shows the default behavior in each case.

    • Default VPC: true

    • VPC: false

    If no DB subnet group has been specified as part of the request and the PubliclyAccessible value has not been set, the DB instance is publicly accessible. If a specific DB subnet group has been specified as part of the request and the PubliclyAccessible value has not been set, the DB instance is private.

  • :auto_minor_version_upgrade (Boolean) —

    Indicates that minor version upgrades are applied automatically to the DB instance during the maintenance window.

  • :license_model (String) —

    License model information for the restored DB instance.

    Default: Same as source.

    Valid values: license-included | bring-your-own-license | general-public-license

  • :db_name (String) —

    The database name for the restored DB instance.

    This parameter doesn't apply to the MySQL, PostgreSQL, or MariaDB engines.

  • :engine (String) —

    The database engine to use for the new instance.

    Default: The same as source

    Constraint: Must be compatible with the engine of the source. For example, you can restore a MariaDB 10.1 DB instance from a MySQL 5.6 snapshot.

    Valid Values:

    • mariadb

    • mysql

    • oracle-ee

    • oracle-se2

    • oracle-se1

    • oracle-se

    • postgres

    • sqlserver-ee

    • sqlserver-se

    • sqlserver-ex

    • sqlserver-web

  • :iops (Integer) —

    Specifies the amount of provisioned IOPS for the DB instance, expressed in I/O operations per second. If this parameter is not 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.

#wait_until(options = {}, &block) ⇒ 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) {|instance| instance.state.name == 'running' }

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

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
