describe-db-snapshots

Description

Returns information about DB snapshots. This API action supports pagination.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

describe-db-snapshots is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: DBSnapshots

Options

--db-instance-identifier (string)

The ID of the DB instance to retrieve the list of DB snapshots for. This parameter can’t be used in conjunction with DBSnapshotIdentifier . This parameter isn’t case-sensitive.

Constraints:

  • If supplied, must match the identifier of an existing DBInstance.

--db-snapshot-identifier (string)

A specific DB snapshot identifier to describe. This parameter can’t be used in conjunction with DBInstanceIdentifier . This value is stored as a lowercase string.

Constraints:

  • If supplied, must match the identifier of an existing DBSnapshot.

  • If this identifier is for an automated snapshot, the SnapshotType parameter must also be specified.

--snapshot-type (string)

The type of snapshots to be returned. You can specify one of the following values:

  • automated - Return all DB snapshots that have been automatically taken by Amazon RDS for my AWS account.

  • manual - Return all DB snapshots that have been taken by my AWS account.

  • shared - Return all manual DB snapshots that have been shared to my AWS account.

  • public - Return all DB snapshots that have been marked as public.

  • awsbackup - Return the DB snapshots managed by the AWS Backup service. For information about AWS Backup, see the ` AWS Backup Developer Guide. https://docs.aws.amazon.com/aws-backup/latest/devguide/whatisbackup.html`__ The awsbackup type does not apply to Aurora.

If you don’t specify a SnapshotType value, then both automated and manual snapshots are returned. Shared and public DB snapshots are not included in the returned results by default. You can include shared snapshots with these results by enabling the IncludeShared parameter. You can include public snapshots with these results by enabling the IncludePublic parameter.

The IncludeShared and IncludePublic parameters don’t apply for SnapshotType values of manual or automated . The IncludePublic parameter doesn’t apply when SnapshotType is set to shared . The IncludeShared parameter doesn’t apply when SnapshotType is set to public .

--filters (list)

A filter that specifies one or more DB snapshots to describe.

Supported filters:

  • db-instance-id - Accepts DB instance identifiers and DB instance Amazon Resource Names (ARNs).

  • db-snapshot-id - Accepts DB snapshot identifiers.

  • dbi-resource-id - Accepts identifiers of source DB instances.

  • snapshot-type - Accepts types of DB snapshots.

  • engine - Accepts names of database engines.

(structure)

A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as IDs. The filters supported by a describe operation are documented with the describe operation.

Note

Currently, wildcards are not supported in filters.

The following actions can be filtered:

  • DescribeDBClusterBacktracks

  • DescribeDBClusterEndpoints

  • DescribeDBClusters

  • DescribeDBInstances

  • DescribePendingMaintenanceActions

Name -> (string)

The name of the filter. Filter names are case-sensitive.

Values -> (list)

One or more filter values. Filter values are case-sensitive.

(string)

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Values": ["string", ...]
  }
  ...
]

--include-shared | --no-include-shared (boolean)

A value that indicates whether to include shared manual DB cluster snapshots from other AWS accounts that this AWS account has been given permission to copy or restore. By default, these snapshots are not included.

You can give an AWS account permission to restore a manual DB snapshot from another AWS account by using the ModifyDBSnapshotAttribute API action.

--include-public | --no-include-public (boolean)

A value that indicates whether to include manual DB cluster snapshots that are public and can be copied or restored by any AWS account. By default, the public snapshots are not included.

You can share a manual DB snapshot as public by using the ModifyDBSnapshotAttribute API.

--dbi-resource-id (string)

A specific DB resource ID to describe.

--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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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

Example 1: To describe a DB snapshot for a DB instance

The following describe-db-snapshots example retrieves the details of a DB snapshot for a DB instance.

aws rds describe-db-snapshots \
    --db-snapshot-identifier mydbsnapshot

        }
    ]
}

For more information, see Creating a DB Snapshot in the Amazon RDS User Guide.

Example 2: To find the number of manual snapshots taken

The following describe-db-snapshots example uses the length operator in the --query option to return the number of manual snapshots that have been taken in a particular AWS Region.

aws rds describe-db-snapshots \
    --snapshot-type manual \
    --query "length(*[].{DBSnapshots:SnapshotType})" \
    --region eu-central-1

Output:

35
