// 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
