What is a snapshot

A snapshot can retain the state of disk data at a point in time. With snapshots, you can quickly and easily restore the ECS to its previous state. For this reason, ECS snapshots are mainly used in development and test environments. If you need to recreate a specific state or condition to solve the problem, it is very useful to master a simple way to restore ECS.
