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 may or may not 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)
Provisioned read and write capacity
For .NET Core, PCL and Unity this operation is only available in asynchronous form. Please refer to CreateBackupAsync.
public virtual CreateBackupResponse CreateBackup( CreateBackupRequest request )

|InternalServerErrorException||An error occurred on the server side.|
|LimitExceededException||Up to 50 CreateBackup operations are allowed per second, per account. There is no limit to the number of daily on-demand backups that can be taken. Up to 10 simultaneous table operations are allowed per account. These operations include CreateTable, UpdateTable, DeleteTable,UpdateTimeToLive, and RestoreTableFromBackup. For tables with secondary indexes, only one of those tables can be in the CREATING state at any point in time. Do not attempt to create more than one such table simultaneously. The total limit of tables in the ACTIVE state is 250. For tables with secondary indexes, only one of those tables can be in the CREATING state at any point in time.
