Description

The Remove-VMSnapshot cmdlet deletes a virtual machine checkpoint.

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:\> Get-VM TestVM | Remove-VMSnapshot -Name Experiment*

Deletes all checkpoints of virtual machine TestVM whose names starts with Experiment.

Example 2

PS C:\> Get-VMSnapshot -VMName TestVM | Where-Object {$_.CreationTime -lt (Get-Date).AddDays(-90) } | Remove-VMSnapshot

Deletes all checkpoints of virtual machine TestVM older than 90 days.
