Alibaba Cloud Object Storage Service (OSS) is a massive, highly available, secured, and cost-effective storage service. One of the special characteristics of OSS is its superior data reliability due to its underlying backup technology and policies. Which of the following statements about OSS backup is correct?

You are designing a solution for a startup company, the proposed solution is like this You suggest they use ECS instances to process requests from mobile App clients, and use SLB to distribute data traffic and ensure the load across each backend ECS instance is balanced.

Moreover to deal with volatile fluctuations in business volume (page views are much higher on the weekends), you also suggest they use Auto Scaling to dynamically increase or reduce computing resources.

The company is satisfied with the solution you proposed. However, they have one concern that when removing an idle instance from the scaling group: if Auto Scaling shuts the instance down directly, the service running on that instance will be abruptly terminated, resulting in poor user experience.

In order to eliminate your customer's concern, which of the following solutions should you recommend them?

A large shopping mall deploys a new video surveillance system. The five-floor building in which the mall is located has installed 35 HD cameras to monitor the major exits. The surveillance system is deployed on an ECS instance, which has four 2 TB data disks to store video data.

However, video data grows so rapidly that the engineers find the ECS will run out of storage space within 2 weeks.

In this case, ___________ product is thought to be the best solution for addressing the storage challenge while ensuring quick access to historical video data when needed.
