Dear Axe,

Here is the definition:

EVS disk snapshot is an important data recovery method that records the status of EVS disk

data at a specific point in time. The snapshot created for an EVS disk at a certain point in time

is independent from the life cycle of the EVS disk. The snapshot can be used to roll back and

restore data of the EVS disk at the time when the snapshot was taken.

You can create an EVS disk from a snapshot. The created EVS disk contains the data of the

snapshot, and is a precise copy of the source EVS disk. An EVS disk created from a snapshot

does not need to be partitioned or formatted, and no file system needs to be created. When the

EVS disk is attached to an instance, the EVS disk can read and write data. Therefore, the

snapshot is an important way of sharing and migrating data

Thanks.

Hi user!
A snapshot is a complete copy or image of a HUAWEI CLOUD EVS disk at a certain time. A snapshot of an EVS disk can be created to store the EVS disk data of the current time point. You can create a snapshot for either the system disk or data disk.

Prerequisites:
The HUAWEI CLOUD EVS disk has been created. For details, see Applying for a HUAWEI CLOUD EVS Disk.
Snapshots can be created for EVS disks in the Available or In-use state.

Creating a HUAWEI CLOUD EVS Disk from a Snapshot

You can create a HUAWEI CLOUD EVS disk using a snapshot on the Snapshot page. The HUAWEI CLOUD EVS disk can either be a system disk or data disk.

Deleting a Snapshot

If a snapshot is no longer used, you can delete it to release the virtual resource.
