Cmdlets are usually implemented around resource operations. The four basic operations are CREATE, READ, UPDATE and DELETE. This set of operations is known as CRUD. Most of the cmdlets support CRUD which are respectively cmdlets that start with the New/Get/Set/Remove cmdlet verbs but they also may have additional operations.
Step 1: Retrieve a object by running a Get command
You can READ objects by using Get-Snapshot cmdlet.
Step 2: Run commands from the CRUD group
You can CREATE objects by using New-Snapshot cmdlet. See example below:New-Snapshot -VM VM -Name BeforePatch
Set-Snapshot -Snapshot $snapshot -Name BeforePatch -Description "Before windows update"
You can REMOVE objects by using Remove-Snapshot cmdlet.
