Hello,
I am trying to write a script which will remove a snapshot task once the remove-snapshot has run and completed. I am having some problem creating the commands. Please can someone assist. I have a script which creates the snapshot tasks but can't figure out how to make one to remove the snapshot task. Please can someone help me fix this? Thank you for your assistance.
Here is an example of my code below. The first one doesn't remove the task. The second works and creates the task.
# Remove Snapshots after Windows Patching
Param(
[Parameter(Mandatory=$true)]
[string]$name, # Description of the snapshot "Windows Patching Staging 1" or "Windows Patching Staging 2"
[string]$path # Path to the host file used for creating the snapshots prior to patching
);
$vms = (Get-Content $path).Split("`n");
$inLine = @();
foreach ($vm in $vms) {
$inLine += Get-VM $vm | Get-Snapshot | fl
if (Get-VM $vm | Get-Snapshot | Where-Object {$_.Description -eq $name} | select VM,Description,Created) {
Get-Snapshot -VM $vm -Name $name | Remove-Snapshot -Confirm:$false
$inLine += Write-Host $vm ": Removed snapshot"}
else {
(Get-VM $vm | Get-Snapshot | Where-Object {$_.Description -eq $name} | select VM,Description,Created)
$inLine += Write-Host $vm ": Could not locate snapshot with that description"}
};
foreach ($vm in $vms) {
if ((Get-View ScheduledTaskManager).ScheduledTask | %{ (Get-View $_).Info } | Where-Object {$_.Name -match ".*$vm.*"}) {
$inLine += (Get-View ScheduledTaskManager).ScheduledTask | %{ (Get-View $_).Info } | Where-Object {$_.Name -match ".*$vm.*"}
((Get-View ScheduledTaskManager).ScheduledTask | %{ (Get-View $_).Info } | Where-Object {$_.Name -match ".*$vm.*"}).RemoveScheduledTask
}
else {
$inLine += Write-Host $vm ": Could not locate snapshot task with that description"}
};
$inline;
