AnswerA Point-in-time recovery helps protect your DynamoDB tables from accidental write or delete operations. With point-in-time recovery, you don't have to worry about creating, maintaining, or scheduling on-demand backups. For example, suppose that a test script writes accidentally to a production DynamoDB table. With point-in-time recovery, you can restore that table to any point in time during the last 35 days. After you enable point-in-time recovery, you can restore to any point in time from five minutes before the current time until 35 days ago. DynamoDB maintains incremental backups of your table. https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/PointInTimeRecovery.html
