The answer provided for this question is unacceptable.
错误我来自Powershell：
Cannot convert argument "srv", with value: "[DBADEV\SQL2008r2]", for "SqlBackup" to type "Microsoft.SqlServer.Management.Smo.Server": "Cannot convert the "[DBADEV\SQL2008r2]" value of type
"Microsoft.SqlServer.Management.Smo.Server" to type "Microsoft.SqlServer.Management.Smo.Server"."
At line:23 char:1
+ $backup.SqlBackup($srv)
+ ~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : MethodArgumentConversionInvalidCastArgument
我尝试编写PowerShell脚本，以便从我们的“生产”框和DBADEV框中恢复数据库。下面是我使用的代码，然后产生错误。
#Clear Screen
cls
#load assemblies
[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') | out-null
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SmoExtended") | Out-Null
$ErrorActionPreference = "Inquire"
# Restore [SQLSRV2k8-0102\SQL2008] instance
$BackupFile = Get-ChildItem "\\NetworkShare\r`$\MSSQL10.SQL2008\MSSQL\Backup\AdventureWorks2008r2" | select -Last 1
$BackupFile
$srv = New-Object Microsoft.SqlServer.Management.Smo.Server("DBADEV\SQL2008r2")
$res = New-Object Microsoft.SqlServer.Management.Smo.Restore
$backup = New-Object Microsoft.SqlServer.Management.Smo.Backup
$Backup.Devices.AddDevice($BackupFile, [Microsoft.SqlServer.Management.Smo.DeviceType]::File)
$Backup.Database = "AdventureWorks2008r2"
$Backup.Action = [Microsoft.SqlServer.Management.Smo.BackupActionType]::Database
$backup.Initialize = $true
$backup.SqlBackup($srv)
$srv.Databases["AdventureWorks2008r2"].Drop()
$res.Devices.AddDevice($BackupFile, [Microsoft.SqlServer.Management.Smo.DeviceType]::File)
$res.Database = "AdventureWorks2008r2"
$res.NoRecovery = $true
$res.SqlRestore($srv)
这个错误对我来说似乎有点神秘（大多数PowerShell错误也是如此）。有关为何发生这种情况的任何想法？当我在这里使用Mike Fal的powershell脚本时，我也收到错误：http://www.mikefal.net/2014/07/22/restoreautomation-powershell-module/
