What Is VMware Snapshot?

VMware snapshots are used to back up VMs and data. If server operations are incorrect or website data needs to be restored, all systems can be restored using the snapshots.

Advantages

VMware Snapshot allows you to back up VMware Elastic Cloud Servers (ECSs), and use the backup data to restore the VMware ECSs. This avoids irreversible loss caused by misoperations.

Application Scenarios

If a misoperation occurs during the use of products provided by VMware Service, you can use the snapshots to restore VMware ECSs. Figure 40-14 shows the details.

Accessing and Using VMware Snapshot

FusionCloud provides a web-based service management platform, which users can access with the ManageOne operation plane or API.

  • ManageOne operation plane

    Users can use the ManageOne operation plane to access the cloud service. If you are a VDC administrator, VDC operator, or have the operation rights for the cloud service, you can directly log in to the ManageOne operation plane and choose this cloud service on the Product List or Console menu.

  • API

    If you want to integrate the service into a third-party system for secondary development, you can access the service using API. For details, see the API reference of the cloud service in FusionCloud 6.3.1.1 API Reference.
