Description

The Checkpoint-VM cmdlet creates a checkpoint of a virtual machine.

Note: In Windows Server 2012 R2, virtual machine snapshots were renamed to virtual machine checkpoints. For clarity, this document will refer to virtual machine snapshots as checkpoints.

Examples

Example 1

PS C:\> Checkpoint-VM -Name Test -SnapshotName BeforeInstallingUpdates

Checkpoints virtual machine Test, creating a checkpoint of it named BeforeInstallingUpdates.

Example 2

PS C:\> Get-VM Test -ComputerName Server1 | Checkpoint-VM

Checkpoints virtual machine Test on Hyper-V host Server1.
