Windows Powershell 3.0を使用してSQL Serverデータベースを復元する

PowerShellスクリプトを使用してSQL Serverデータベースを復元しようとしていますが、問題があります。

ここに私が得ているエラーがあります：

"1"引数を使用して "SqlRestore"を呼び出す例外： "サーバー 'WUSFK250042-OLU\SQLSERVER2008R2'の復元に失敗しました。"行：48 char：1 + $ smoRestore.SqlRestore（$ server） =

これが私のコードです：

#clear screen
cls

#load assemblies
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") | Out-Null
#Need SmoExtended for backup
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SmoExtended") | Out-Null
[Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.ConnectionInfo") | Out-Null
[Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SmoEnum") | Out-Null

$backupFile = "C:\SafewayRT\SafewayRTFUll.bak"

#we will query the database name from the backup header later
$server = New-Object ("Microsoft.SqlServer.Management.Smo.Server") "WUSFK250042-OLU\SQLSERVER2008R2"
$backupDevice = New-Object("Microsoft.SqlServer.Management.Smo.BackupDeviceItem") ($backupFile, "File")
$smoRestore = new-object("Microsoft.SqlServer.Management.Smo.Restore")

#restore settings
$smoRestore.NoRecovery = $false;
$smoRestore.ReplaceDatabase = $true;
$smoRestore.Action = "Database"
$smoRestorePercentCompleteNotification = 10;
$smoRestore.Devices.Add($backupDevice)

#get database name from backup file
$smoRestoreDetails = $smoRestore.ReadFileList($server)

#display database name
"Database Name from Backup Header : " +$smoRestoreDetails.Rows[0]["Safeway_LogixRT"]

#give a new database name
$smoRestore.Database =$smoRestoreDetails.Rows[0]["Safeway_LogixRT"]

#specify new data and log files (mdf and ldf)
$smoRestoreFile = New-Object("Microsoft.SqlServer.Management.Smo.RelocateFile")
$smoRestoreLog = New-Object("Microsoft.SqlServer.Management.Smo.RelocateFile")

#the logical file names should be the logical filename stored in the backup media
$smoRestoreFile.LogicalFileName = $smoRestoreDetails.Rows[0]["Safeway_LogixRT"]
$smoRestoreFile.PhysicalFileName = $server.Information.MasterDBPath + "\" + $smoRestore.Database + "_Data.mdf"
$smoRestoreLog.LogicalFileName = $smoRestoreDetails.Rows[0]["Safeway_LogixRT"] + "_Log"
$smoRestoreLog.PhysicalFileName = $server.Information.MasterDBLogPath + "\" + $smoRestore.Database + "_Log.ldf"
$smoRestore.RelocateFiles.Add($smoRestoreFile)
$smoRestore.RelocateFiles.Add($smoRestoreLog)

#restore database
$smoRestore.SqlRestore($server)

私は同様の問題を抱えていましたが、私のバックアップファイルには、ターゲットDBで間違ったパスが含まれる複数のファイルが含まれていました。これが完全なソリューションです。

[Microsoft.SqlServer.Management.Smo.Server]$server = New-Object ("Microsoft.SqlServer.Management.Smo.Server") "(local)"

$backupDevice = New-Object ("Microsoft.SqlServer.Management.Smo.BackupDeviceItem") ($backupFile, "File")
$smoRestore = New-Object Microsoft.SqlServer.Management.Smo.Restore

$smoRestore.NoRecovery = $false;
$smoRestore.ReplaceDatabase = $true;
$smoRestore.Action = "Database"
$smoRestore.PercentCompleteNotification = 10;
$smoRestore.FileNumber = 0
$smoRestore.Devices.Add($backupDevice)

# Get the details from the backup device for the database name and output that
$smoRestoreDetails = $smoRestore.ReadBackupHeader($server)
"Database Name from Backup Header : " + $databaseName

$dbLogicalName = ""
$logLogicalName = ""

$logicalFileNameList = $smoRestore.ReadFileList($server)
foreach($row in $logicalFileNameList)
{ 
   $smoRestore.Database = $smoRestoreDetails.Rows[0]["DatabaseName"]

   $fileType = $row["Type"].ToUpper()
   if ($fileType.Equals("D")) 
   {
      $dbLogicalName = $row["LogicalName"]
      $smoRestoreFile = New-Object("Microsoft.SqlServer.Management.Smo.RelocateFile") 
      $smoRestoreFile.LogicalFileName = $dbLogicalName
      $smoRestoreFile.PhysicalFileName = $server.Information.MasterDBPath + "\" + $dbLogicalName + "_Data.mdf"
      $smoRestoreFile
      $smoRestore.RelocateFiles.Add($smoRestoreFile)
   }
   elseif ($fileType.Equals("L")) 
   {

   }
}

$server.KillAllProcesses($databaseName)
$smoRestore.SqlRestore($server)

問題が何であるかを確認するには、その例外に入る必要があります。 Powershellは、ヒープである$ Errorと呼ばれるシステム変数でエラーを追跡します（つまり、インデックス0が最新のエラーです）。私は通常次のようなことをします：

$e = $error[0]
$e.Exception
$e.Exception.InnerException
$e.Exception.InnerException.InnerException
...

本当のエラーを見つけるまで。実際の復元に問題がある可能性があります（つまり、その名前のデータベースがすでに存在している、物理ファイルへの不正なパスなど）。しかし、その例外の根本にたどり着くまで、あなたにはわかりません！

今日この問題があり、バックアップと復元を実現するためにCmdLetを作成しました。私はそれをgithubに置きます： SqlBackupRestore.ps1 これも以下に再現されます：
