Community Answer: C

On-demand backup allows you to create full backups of your Amazon DynamoDB table for data archiving, helping you meet your corporate and governmental regulatory requirements. You can back up tables from a few megabytes to hundreds of terabytes of data, with no impact on performance and availability to your production applications. Backups process in seconds regardless of the size of your tables, so you do not have to worry about backup schedules or long-running processes. In addition, all backups are automatically encrypted, cataloged, easily discoverable, and retained until explicitly deleted.
