      • In the navigation pane on the left side of the console, choose Backups. Then choose Create backup.

    3. Make sure that Music is the table name, and enter MusicBackup for the backup name. Then, choose Create backup to create the backup.

      Create backup console screen with the table name and backup name filled in.

    Follow these steps to create a backup for an existing table Music using the AWS CLI.

    To create a table backup

    • Create a backup with the name MusicBackup for the Music table.

      aws dynamodb create-backup --table-name Music \
 --backup-name MusicBackup

      While the backup is being created, the backup status is set to CREATING.

      {
    "BackupDetails": {
        "BackupName": "MusicBackup", 
        "BackupArn": "arn:aws:dynamodb:us-east-1:123456789012:table/Music/backup/01489602797149-73d8d5bc", 
        "BackupStatus": "CREATING", 
        "BackupCreationDateTime": 1489602797.149
    }
}

    After the backup is complete, its BackupStatus should change to AVAILABLE. To confirm this, use the describe-backup command. You can get the input value of backup-arn from the output of the previous step or by using the list-backups command.

    aws dynamodb describe-backup \
--backup-arn arn:aws:dynamodb:us-east-1:123456789012:table/Music/backup/01489173575360-b308cd7d

    To keep track of your backups, you can use the list-backups command. It lists all your backups that are in CREATING or AVAILABLE status.

    aws dynamodb list-backups

    The list-backups command and the describe-backup command are useful to check information about the source table of the backup.
