#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:

    • 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 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 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 are not copied.

  • :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. Don't specify PreSignedUrl when you are copying an encrypted DB snapshot in the same AWS Region.

    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.

    If you are using an AWS SDK tool or the AWS CLI, you can specify SourceRegion (or --source-region for the AWS CLI) instead of specifying PreSignedUrl manually. Specifying SourceRegion autogenerates a pre-signed URL that is a valid request for the operation that can be executed in the source AWS 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 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 in the Amazon RDS User Guide.

  • :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:

Parameters:

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

    ({})

Options Hash (options):

  • :db_instance_identifier (required, String) —

    Name of the DB instance to create from the DB snapshot. This parameter isn't case-sensitive.

    Constraints:

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

    • First character must be a letter

    • Can't 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 Availability Zone (AZ) where the DB instance will be created.

    Default: A random, system-chosen Availability Zone.

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

    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) —

    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 DNS endpoint resolves to the private IP address from within the DB instance's VPC, and 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, and 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.

  • :auto_minor_version_upgrade (Boolean) —

    A value that indicates whether 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

    The name of the option group to be used for the restored DB instance.

    Permanent options, such as the TDE option for Oracle Advanced Security TDE, can't be removed from an option group, and that option group can't be removed from a DB instance once it is associated with a DB instance

  • :tags (Array<Types::Tag>) —

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

  • :storage_type (String) —

    Specifies the storage type to be associated with the DB instance.

    Valid values: standard | gp2 | io1

    If you specify io1, you must also include a value for the Iops parameter.

    Default: io1 if the Iops parameter is specified, otherwise gp2

  • :tde_credential_arn (String) —

    The ARN from the key store with which to associate the instance for TDE encryption.

    A list of EC2 VPC security groups to associate with this DB instance.

    Default: The default EC2 VPC security group for the DB subnet group's VPC.

  • :domain (String) —

    Specify the Active Directory directory ID to restore the DB instance in. The domain must be created prior to this operation. Currently, only MySQL, Microsoft SQL Server, Oracle, and PostgreSQL DB instances can be created in an Active Directory Domain.

    For more information, see Kerberos Authentication in the Amazon RDS User Guide.

  • :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. By default, tags are not copied.

#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
