SQL Server备份脚本（PowerShell）可在2016服务器上运行，但不能在2012上运行

Question

我有以下脚本：

$serverName = "."
$backupDirectory = "\\backup\server1"
$daysToStoreDailyBackups = 7
$daysToStoreWeeklyBackups = 28
$monthsToStoreMonthlyBackups = 3

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") | Out-Null
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SmoExtended") | Out-Null
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.ConnectionInfo") | Out-Null
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SmoEnum") | Out-Null

$mySrvConn = new-object Microsoft.SqlServer.Management.Common.ServerConnection
$mySrvConn.ServerInstance=$serverName
$mySrvConn.LoginSecure = $false
$mySrvConn.Login = "sa"
$mySrvConn.Password = "myPass"

$server = new-object Microsoft.SqlServer.Management.SMO.Server($mySrvConn)

$dbs = $server.Databases
$startDate = (Get-Date)
"$startDate"

Get-ChildItem "$backupDirectory\*_daily.bak" |? { $_.lastwritetime -le (Get-Date).AddDays(-$daysToStoreDailyBackups)} |% {Remove-Item $_ -force }
"removed all previous daily backups older than $daysToStoreDailyBackups days"

foreach ($database in $dbs | where {$_.IsSystemObject -eq $False})
{
    $dbName = $database.Name      

    if ($dbName -ne "ReportServer" -and $dbName -ne "ReportServerTempDB")
    {
        $timestamp = Get-Date -format yyyy-MM-dd-HHmmss
        $targetPath = $backupDirectory + "\" + $dbName + "_" + $timestamp + "_daily.bak"

        $smoBackup = New-Object ("Microsoft.SqlServer.Management.Smo.Backup")
        $smoBackup.Action = "Database"
        $smoBackup.BackupSetDescription = "Full Backup of " + $dbName
        $smoBackup.BackupSetName = $dbName + " Backup"
        $smoBackup.Database = $dbName
        $smoBackup.MediaDescription = "Disk"
        $smoBackup.Devices.AddDevice($targetPath, "File")
        $smoBackup.SqlBackup($server) 
        "backed up $dbName ($serverName) to $targetPath"    
    }
    else
    {
        "$dbName backup skipped"
    }
}

if([Int] (Get-Date).DayOfWeek -eq 0)
{
    Get-ChildItem "$backupDirectory\*_weekly.bak" |? { $_.lastwritetime -le (Get-Date).AddDays(-$daysToStoreWeeklyBackups)} |% {Remove-Item $_ -force }
    "removed all previous daily backups older than $daysToStoreWeeklyBackups days"

    foreach ($database in $dbs | where { $_.IsSystemObject -eq $False})
    {
        $dbName = $database.Name  

        if ($dbName -ne "ReportServer" -and $dbName -ne "ReportServerTempDB")
        {    
            $timestamp = Get-Date -format yyyy-MM-dd-HHmmss
            $targetPath = $backupDirectory + "\" + $dbName + "_" + $timestamp + "_weekly.bak"

            $smoBackup = New-Object ("Microsoft.SqlServer.Management.Smo.Backup")
            $smoBackup.Action = "Database"
            $smoBackup.BackupSetDescription = "Full Backup of " + $dbName
            $smoBackup.BackupSetName = $dbName + " Backup"
            $smoBackup.Database = $dbName
            $smoBackup.MediaDescription = "Disk"
            $smoBackup.Devices.AddDevice($targetPath, "File")
            $smoBackup.SqlBackup($server) 
            "backed up $dbName ($serverName) to $targetPath"
        } 
        else
        {
            "$dbName backup skipped"
        }                   
    }
}

if([Int] (Get-Date).Day -eq 1)
{
    Get-ChildItem "$backupDirectory\*_monthly.bak" |? { $_.lastwritetime -le (Get-Date).AddMonths(-$monthsToStoreMonthlyBackups)} |% {Remove-Item $_ -force }
    "removed all previous monthly backups older than $monthsToStoreMonthlyBackups days"

    foreach ($database in $dbs | where { $_.IsSystemObject -eq $False})
    {
        $dbName = $database.Name  

        if ($dbName -ne "ReportServer" -and $dbName -ne "ReportServerTempDB")
        {
            $timestamp = Get-Date -format yyyy-MM-dd-HHmmss
            $targetPath = $backupDirectory + "\" + $dbName + "_" + $timestamp + "_monthly.bak"

            $smoBackup = New-Object ("Microsoft.SqlServer.Management.Smo.Backup")
            $smoBackup.Action = "Database"
            $smoBackup.BackupSetDescription = "Full Backup of " + $dbName
            $smoBackup.BackupSetName = $dbName + " Backup"
            $smoBackup.Database = $dbName
            $smoBackup.MediaDescription = "Disk"
            $smoBackup.Devices.AddDevice($targetPath, "File")
            $smoBackup.SqlBackup($server) 
            "backed up $dbName ($serverName) to $targetPath" 
        } 
        else
        {
            "$dbName backup skipped"
        }               
    }
}

这在我的一台服务器（运行服务器2016）上完美运行，在另一台服务器（运行服务器2012）上却没有运行，这给我以下错误：

Exception calling "SqlBackup" with "1" argument(s): "Backup failed for Server 'Server1'. "
At C:\Users\Administrator\Documents\Scripts\sqlFullBackup.ps1:43 char:9
+         $smoBackup.SqlBackup($server)
+         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : FailedOperationException

任何想法如何解决这个问题？

提前致谢

跑步时

$error[0] | fl -force

我得到以下内容：

System.Data.SqlClient.SqlException: Cannot open backup device '\\ServerAddress\Folder\file_2017-06-17-110451_daily.bak'. Operating system error 5(Access is denied.).

我在sql server 2012上测试了脚本，并成功备份到本地文件夹。

您的脚本运行正常。

尝试（以进行测试）备份到服务器上的本地文件夹。

确定：

• 您已安装Microsoft SQL Server 2012的Microsoft Windows PowerShell扩展（带有SMO）。 有关详细信息，请阅读我的答案： 执行SQL Server PowerShell模块需要什么

• 您的服务器对共享文件夹“ \\\\ backup \\ server1”具有访问权限。 在服务器2012中，在共享文件夹“ \\\\ backup \\ server1”上为MSSQLSERVER帐户设置权限R / W

编辑：

根据您的评论，脚本可以通过使用本地文件夹正常运行。 因此，问题在于共享文件夹的设置。

在工作组环境中

如果SQL Server 2012在WORKGROUP环境中工作：

• 在sql server 2012和备份服务器上（使用计算机管理器）创建具有相同密码（例如'sql2012'）的相同窗口用户帐户。

• 将此帐户（sql2012 / password）设置为运行sql服务的帐户（使用Sql Server配置管理器工具）。

• 在备份服务器中，将共享文件夹“完全读写”的权限设置为帐户sql2012

在域环境中

• 使用域帐户作为运行sql服务的帐户（使用Sql Server配置管理器工具）

• 在备份服务器中，将共享文件夹Full R / W中的权限设置为该域帐户。
