SQL Server 2008 doesn't use backup device path when running powershell script from prompt

Question

I made a script that backups all of the databases of my remote server. When I run the script from the PowerShell ISE interface, the path that I determine in the backup device works fine, but when I run it from the prompt, the path I set is ignored, and the backup is made to SQL Server's default backup directory. Why is that, and how can I fix it? Below is my script:

$DestSqlTpb = "E:\BackupBD\SQL-TPB-01\";
$PastaRede = "\\sql-tpb1-01\BackupBD\SQL-TPB-01\";
Write-Output ("Started DELETE at: " + (Get-Date -format yyyy-MM-dd-HH:mm:ss));    
$ComandoDeleteRede = $PastaRede + "*"
remove-item $ComandoDeleteRede
$ComandoSqlTpbLocal = $DestSqlTpb + "*"
remove-item $ComandoSqlTpbLocal
Write-Output ("Finished DELETE at: " + (Get-Date -format yyyy-MM-dd-HH:mm:ss));    
[void][System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.ConnectionInfo');            
[void][System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.Management.Sdk.Sfc');            
[void][System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO');
[void][System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMOExtended');  
$Server = "SQL-TPB1-01\SQL2008";     # SQL Server Instance.    
$srv = new-object ("Microsoft.SqlServer.Management.Smo.Server") $Server

Write-Output ("Started SQL-TPB1-01 at: " + (Get-Date -format yyyy-MM-dd-HH:mm:ss));
$dbs = $srv.Databases
foreach ($db in $dbs) 
{
  if (($db.Name -ne "tempdb") -and (!$db.IsDatabaseSnapshot)) #We don't want to backup the tempdb database 
  {
    $timestamp = Get-Date -format yyyy-MM-dd-HH-mm-ss;
    $backup = New-Object ("Microsoft.SqlServer.Management.Smo.Backup");            
    $backup.Action = "Database";            
    $backup.Database = $db.Name;            
    $backup.Devices.AddDevice($Dest + $db.Name + "_full_" + $timestamp + ".bak", "File");            
    $backup.BackupSetDescription = "Full backup of " + $db.Name + " " + $timestamp;            
    $backup.Incremental = 0;     
    $backup.CompressionOption = 1;
    # Starting full backup process.            
    $backup.SqlBackup($srv);     
    # For db with recovery mode <> simple: Log backup.            
    If ($db.RecoveryModel -ne 3)            
    {            
        $timestamp = Get-Date -format yyyy-MM-dd-HH-mm-ss;            
        $backup = New-Object ("Microsoft.SqlServer.Management.Smo.Backup");            
        $backup.Action = "Log";            
        $backup.Database = $db.Name;            
        $backup.Devices.AddDevice($Dest + $db.Name + "_log_" + $timestamp + ".trn", "File");            
        $backup.BackupSetDescription = "Log backup of " + $db.Name + " " + $timestamp;            
        #Specify that the log must be truncated after the backup is complete.            
        $backup.LogTruncation = "Truncate";
        # Starting log backup process            
        $backup.SqlBackup($srv);    
    };
  };
};
Write-Output ("Finished SQL-TPB1-01 at: " + (Get-Date -format yyyy-MM-dd-HH:mm:ss));
Write-Output ("Started COPY at: " + (Get-Date -format yyyy-MM-dd-HH:mm:ss));    
copy-item $ComandoDeleteRede $DestSqlTpb
Write-Output ("Finished COPY at: " + (Get-Date -format yyyy-MM-dd-HH:mm:ss));

When I just Run from ISE, it goes well, but if I save the ps1 file, and execute from prompt, the path in the device is ignored. Tks

any final and full source code script working?

I'm betting the problem is with this line:

$backup.Devices.AddDevice($Dest + $db.Name + "_full_" + $timestamp + ".bak", "File");

You are using the $Dest variable, which is not defined anywhere in your script. I bet that you have the $Dest variable set to the path you want in the ISE session, which is why it's working there.

But in a new console window, $Dest is null so SQL is using the default path.
