Alibaba Cloud's ECS disk snapshotting tool can create crash-consistent snapshots for all types of Cloud...

A snapshot is a backup file of the cloud disk data state at a certain point in time. The first snapshot of the cloud disk is a full snapshot of the ac usage. Empty data blocks are not backed up. All subsequent snapshots are incremental snapshots, and only changed data blocks are stored.

Snapshots can be created manually through the web console or command line tools, or automatically according to a schedule.

In the event of a system failure, you can use a snapshot to roll back the Cloud Disk to an earlier point in time.

Snapshot rollbacks can be performed while the ECS instance is running.
