Hi
Syntax looks correct but I would look at the job report to see the output, when you run the new-smclone it qeues the job so wouldn't know the result right way you need to look at the report.
--Run Clone command
$clonejob = New-SmClone -CloneLastBackup 0 -Resources @{"host"="Server";"Type"="SQL Database";"
Names"="DBSERVER\DatabaseName"} -AppPluginCode SMSQL -CloneToInstance "CloneServer" -AssignMountPointUnderPath "C:\SQLmntp
nt"
--Get Clone output
Get-SmJobSummaryReport -JobId $clonejob.Job.ID
