Script Error Start-WBBackup (Windows Server Backup SnapIn)

Question

Hi, first of all, i hope that the post location will be the correct, and sorry for my english.
I had this problem with a Script, i'm new in powershell, and hope that you can helpme.
The objective of the script is make a SystemState Backup and send an Email. The fail is in the execution fo the Start-WBBackup cmd-let, the error is about the target of the backup, it says it is not valid, or something like that. Also, the error handling
is not functioning.
I let you the script, hope that you can tellme where is the error, and again, sorry for my english.
Add-PSSnapIn windows.serverbackup
$Equipo = $env:computername
#Parametros Mail
$smtp = "smtp.server"
$from = "Backup User <[email protected]>"
$to = "Alertas IT <[email protected]>"
$body = "Backup SystemState para el equipo: $Equipo"
$subject = "SystemState $Equipo"
#Definir Ubicacion
$backdir = "\\backup-server\share-name\"
$backupLocation = New-WBBackupTarget -network $backdir
$backuplog = "$backdir"+(Get-Date -f yyyyMMdd)+"_SystemState_$Equipo.log"
#Definir Politica
$policy = New-WBPolicy
Add-WBSystemState -Policy $policy
Add-WBBackupTarget -Policy $policy -Target $backupLocation
#Descomentar estas lineas para agregar carpetas/archivos
#$files=new-WBFileSpec S:\IISRoot,c:\Inetpub
#Add folders / source folders into the policy
#Add-wbFileSpec -policy $policy -filespec $files
write-host $policy
#Ejecutar Backup
$Error.Clear()
Start-WBBackup -Policy $policy | Out-File "$backuplog"
if($Error.Count -gt 0) {
$subject = "(FALLO) " + $subject
$body = $body + " ha fallado. Revisar log adjunto"}
$Result = Get-WBSummary | Select LastBackupTime,LastBackupTarget,DetailedMessage | Format-List
#Enviar Mail
$body = $body + "`r`n" + $Result
send-MailMessage -SmtpServer $smtp -From $from -To $to -Subject $subject -Body $body -Attachments $backuplog
write-host $Result
write-host "Backup Completado"
NOTE: I build this, with some sources of web, and a touch of myself...

Answer 1

Are you sure the target path exists?  I'm not having any problems with the code you've got except on Windows 2012 R2 more Policy parameters needed to be set.  The only way I was able to trigger an invalid path error was if the target folder didn't
exist.  A target subfolder will not be created.
I hope this post has helped!
