VMware Snapshot

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 37-14 shows the details.

Workflow

Figure 37-16 shows the VMware EVS workflow.

Figure 37-16 VMware EVS workflow
  1. VDC administrators or VDC operators apply for VMware EVS disks from the ManageOne operation plane. VMware Service delivers the operation requests to Storage for processing.
  2. Scheduler filters and sorts the processed operation requests.
  3. CoreTask processes tasks in sequence.
  4. API Gateway distributes the requests for vCenter systems.

Accessing and Using VMware Snapshot

FusionCloud provides a web-based service management platform. Specifically, users can access the service using 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 of the cloud service, you can directly log in to the ManageOne operation plane and choose this cloud service under the Product List or Console menu.

  • API

    To integrate the cloud service into a third-party system for secondary development, use the corresponding API to access this service. For details, see the FusionCloud 6.3.0 API Reference.
