Create List or Remove VMware VM Snapshots with PowerCLi

This is very handy and useful PowerCLI script, when I do my labs or production deployment changes on VMware environment. Whenever I have multiple servers to make changes and wants to ensure no problem should occur after changes, I take temporary VMware snapshots. But working with snapshot manually in GUI on multiple VMs, it is time consuming and sometimes there is no accuracy. Here to have perfection while creating snapshots I use VMware PowerCLI and automate the task, it saves lots of time with accuracy.

In below script I have lists of VMs and snapshot name. First command is Get-VM and using same information create new snapshot with command New-Snapshot using parameters.

<#
$user =  'Administrator@vsphere.local'
$password = 'password'
Connect-VIServer -Server marvel.vcloud-lab.com -User $user -Password $password
#>

$date = Get-Date 
$vmList = ('k8smaster01', 'k8smaster02', 'k8smaster03','k8sworker01','k8sworker02','k8sworker03')
$snapshotName = 'Fresh Deploy'

$vms = Get-VM -Name $vmList
$vms | New-Snapshot -Name $snapshotName -Description $date.DateTime -Memory:$true -Confirm:$false

I can verify snapshot is created on one of the VM on vCenter UI.

In the last if you want to get the list of snapshots, you can use Get-Snapshot and to delete snapshot use Remove-Snapshot command as shown below.

$vms | Get-Snapshot
$vms | Get-Snapshot | Remove-Snapshot -RemoveChildren -Confirm:$false
