Ron, I like your script a lot, and tried to adjust it for SQL server backup., I load [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") and then try the following:

# Declare SQL objects with strongly typed variables

[Microsoft.SqlServer.SMO.Server]$SQLserver = New-Object ([Microsoft.SqlServer.SMO.Server])

# Connect to SQL Server with specified instance

$SQLserver.Connect($Servername)

but am getting a error:

Unable to find type [Microsoft.SqlServer.SMO.Server]:

or if I try to load just LoadWithPartialName("Microsoft.SqlServer"] that errors out too.

I attach my script here as SQLCMD_v4.ps1.txt
