在PowerCLI中一次删除多个快照

Question

I am trying to delete old snapshots after patching using PowerCLI. The code i am using now is:

Get-VM | Get-Snapshot | Remove-Snapshot -confirm$false

It works great...but it only removes one at a time, and i would like it to do 2-3 at a time. Is this possible?

Thanks in advance!

Answer 1

This code will remove multiple snapshots from all virtual machines:

Get-VM | Get-Snapshot | % { Remove-Snapshot $_ -Confirm:$false }

I would recommend selecting a single virtual machine and testing first:

$VM = Get-VM -Name 'My Virtual Machine'
$VM | Get-Snapshot | % { Remove-Snapshot $_ -Confirm:$false }

Tested to work on PowerCLI 6.5.

Answer 2

I would recommend taking a look at the 'RunAsync' parameter. This will create the task and then move onto the next task without waiting for the prior task to complete.

Example:

Get-VM | Get-Snapshot | Remove-Snapshot -RunAsync -Confirm:$false
