VMware PowerCLI 101 - Part4 - Snapshots

In this post, I will briefly explain how to make use of PowerCLI when working with virtual machine snapshots.

Take a snapshot of VM:
New-Snapshot -VM "New Virtual Machine" -Name snap1 -Description try1

Revert to a snapshot:
$snap = Get-Snapshot -VM "New Virtual Machine" -Name "snap1"
Set-VM -VM "New Virtual Machine" -Snapshot $snap -WhatIf
Set-VM -VM "New Virtual Machine" -Snapshot $snap 

Delete specific snapshot of a VM:
$snap = Get-Snapshot -VM "New Virtual Machine" -Name "snap1"
Remove-Snapshot -Snapshot $snap -WhatIf
Remove-Snapshot -Snapshot $snap 

Delete all snapshots of a VM:
Get-VM "New Virtual Machine" | Get-Snapshot | Remove-Snapshot -WhatIf
Get-VM "New Virtual Machine" | Get-Snapshot | Remove-Snapshot 

List all VMs with snapshots:
Get-VM | Get-Snapshot | Select-Object VM, Name, Description, SizeGB

List VMs with snapshots older than a week:
Get-VM | Get-Snapshot | Where {$PSItem.Created -lt (Get-Date).AddDays(-7)} | Select-Object VM, Name, Description, Created, SizeGB | Format-Table

Find the parent-child relationship of VM snapshots:
$vm = Get-VM "New Virtual Machine"
get-vm $vm | Get-Snapshot | Select VM,Name,Description,Parent,Children,SizeGB,IsCurrent,Created,Id | sort Created |  Format-Table

Hope it was useful. Cheers!
