Limits

The specifications and lifecycle of SSD local disks are tied to the instance. Independent purchase, as well as independent mounting, unmounting, or scaling up, is not supported.

When you delete an instance, data on the local disk will be automatically cleared. Please back up your data in advance.

If the physical server fails or the local disk is damaged, there is a risk of data loss on the local disk. Do not store data that needs to be stored long term on the local disk, and promptly perform data backup.

We recommend that you adopt a high availability architecture by distributing your workloads across multiple instances or using volume backups to ensure high availability and data reliability.

If your application's architecture cannot ensure data reliability, we strongly recommend that you select Volume to back up your data.
