create-backup¶

Description¶

Creates a backup for an existing table.

Each time you create an on-demand backup, the entire table data is backed up. There is no limit to the number of on-demand backups that can be taken.

When you create an on-demand backup, a time marker of the request is cataloged, and the backup is created asynchronously, by applying all changes until the time of the request to the last full table snapshot. Backup requests are processed instantaneously and become available for restore within minutes.

You can call CreateBackup at a maximum rate of 50 times per second.

All backups in DynamoDB work without consuming any provisioned throughput on the table.

If you submit a backup request on 2018-12-14 at 14:25:00, the backup is guaranteed to contain all data committed to the table up to 14:24:00, and data committed after 14:26:00 will not be. The backup might contain data modifications made between 14:24:00 and 14:26:00. On-demand backup does not support causal consistency.

Along with data, the following are also included on the backups:

Global secondary indexes (GSIs)
Local secondary indexes (LSIs)
Streams
Provisioned read and write capacity

Synopsis¶

  create-backup
--table-name <value>
--backup-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--table-name (string)

The name of the table.

--backup-name (string)

Specified name for the backup.

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To create a backup for an existing DynamoDB table

The following create-backup example creates a backup of the MusicCollection table.

aws dynamodb create-backup \
    --table-name MusicCollection \
    --backup-name MusicCollectionBackup

Output:

{
    "BackupDetails": {
        "BackupArn": "arn:aws:dynamodb:us-west-2:123456789012:table/MusicCollection/backup/01576616366715-b4e58d3a",
        "BackupName": "MusicCollectionBackup",
        "BackupSizeBytes": 0,
        "BackupStatus": "CREATING",
        "BackupType": "USER",
        "BackupCreationDateTime": 1576616366.715
    }
}

For more information, see On-Demand Backup and Restore for DynamoDB in the Amazon DynamoDB Developer Guide.

Output¶

BackupDetails -> (structure)

Contains the details of the backup created for the table.

BackupArn -> (string)

ARN associated with the backup.

BackupName -> (string)

Name of the requested backup.

BackupSizeBytes -> (long)

Size of the backup in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

BackupStatus -> (string)

Backup can be in one of the following states: CREATING, ACTIVE, DELETED.

BackupType -> (string)

BackupType:

USER - You create and manage these using the on-demand backup feature.

SYSTEM - If you delete a table with point-in-time recovery enabled, a SYSTEM backup is automatically created and is retained for 35 days (at no additional cost). System backups allow you to restore the deleted table to the state it was in just before the point of deletion.

AWS_BACKUP - On-demand backup created by you from Backup service.

BackupCreationDateTime -> (timestamp)

Time at which the backup was created. This is the request time of the backup.

BackupExpiryDateTime -> (timestamp)

Time at which the automatic on-demand backup created by DynamoDB will expire. This SYSTEM on-demand backup expires automatically 35 days after its creation.
