create-db-snapshot¶

Description¶

Creates a snapshot of a DB instance. The source DB instance must be in the available or storage-optimization state.

Synopsis¶

  create-db-snapshot
--db-snapshot-identifier <value>
--db-instance-identifier <value>
[--tags <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--db-snapshot-identifier (string)

The identifier for the DB 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-snapshot-id

--db-instance-identifier (string)

The identifier of the DB instance that you want to create the snapshot of.

Constraints:

Must match the identifier of an existing DBInstance.

--tags (list)

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}_.:/=+-@]*)$”).

Value -> (string)

A value is the optional value of the tag. The string value can be from 1 to 256 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}_.:/=+-@]*)$”).

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Value": "string"
  }
  ...
]

--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 create a DB snapshot

The following create-db-snapshot example creates a DB snapshot.

Output¶

DBSnapshot -> (structure)

DescribeDBInstances

DescribeDBSnapshots

DescribeValidDBInstanceModifications

If you call DescribeDBInstances , ProcessorFeature returns non-null values only if the following conditions are met:

You are accessing an Oracle DB instance.
