Hyper-V Snapshot

Hyper-V Snapshot

What Is Hyper-V Snapshot?

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

Advantages

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

Application Scenarios

A snapshot is a record of the status of an ECS at a specific time point. If a VM is faulty or services are required, the VM status is restored to the snapshot time point. You can restore the Hyper-V ECS using backups, as shown in Figure 41-10.
