If you look at how “Invoke-Win32″ function is used in his script, you will be able to modify your script a bit cleaner since the one you have posted is, yet, to be cleaned ;)

>I’m having trouble getting $items[0] to expand within a string
You can do the following for variable expansion inside the string.

Instead of
>$serverName = $items[0].trim()
> …
> “$serverName”,…

You can do
… snip …::Backup(“$($item[0].trim())”, …
