Implementing and Working with Backups and Restores in DynamoDB

In this lab, we will explore utilizing on-demand and point-in-time recovery backups for DynamoDB tables. Additionally, we will create scheduled backups using Lambda. A DynamoDB table has been provided with a small amount of data to facilitate creating and restoring DynamoDB backups.
