如何使用 Powershell 啟用卷影複製？

如何在特定驅動器（D:、E:、…）上啟用卷影複製並使用 Powershell 設置計劃？

我只需要一些提示如何開始。

您可以使用 WMI 對像在特定驅動器上創建卷影副本，如Microsoft 文章中所述。

在特定驅動器（D:、E:、…）上啟用卷影複製是兩件事

1. 如上一篇文章所示創建卷影副本
2. 創建計劃任務以創建卷影副本

我花了一點時間才使它起作用（在找到導致它失敗的簡單錯誤之後），並且該功能不完整。我想添加在遠端電腦上啟用它的功能，這可能必須通過執行一次的任務來完成。如果有人修改了這個並添加了那個，請告訴我！

function Enable-ShadowCopies {
param(
   [String]$ComputerName = $Env:ComputerName,

   [Parameter(Mandatory=$true)]
   [String]$Drive
)
$volumeWMI = Get-WmiObject -ComputerName $ComputerName -Class Win32_Volume -Filter "DriveLetter = '$Drive'";
$volumeID = ($volumeWMI.DeviceID.SubString(10)).SubString(0,($volumeWMI.DeviceID.SubString(10)).Length-1);

$scheduler = New-Object -ComObject Schedule.Service
$scheduler.Connect($ComputerName)
$tskDef = $scheduler.NewTask(0);
$tskRegInfo = $tskDef.RegistrationInfo;
$tskSettings = $tskDef.Settings;
$tskTriggers = $tskDef.Triggers;
$tskActions = $tskDef.Actions;
$tskPrincipals = $tskDef.Principal;

# Registration Info
$tskRegInfo.Author = "PowerShell Script";

# Settings
$tskSettings.DisallowStartIfOnBatteries = $false;
$tskSettings.StopIfGoingOnBatteries = $false
$tskSettings.AllowHardTerminate = $false;
$tskSettings.IdleSettings.IdleDuration = "PT600S";
$tskSettings.IdleSettings.WaitTimeout = "PT3600S";
$tskSettings.IdleSettings.StopOnIdleEnd = $false;
$tskSettings.IdleSettings.RestartOnIdle = $false;
$tskSettings.Enabled = $true;
$tskSettings.Hidden = $false;
$tskSettings.RunOnlyIfIdle = $false;
$tskSettings.WakeToRun = $false;
$tskSettings.ExecutionTimeLimit = "PT259200S";
$tskSettings.Priority = "5";
$tskSettings.StartWhenAvailable = $false;
$tskSettings.RunOnlyIfNetworkAvailable = $false;

# Triggers
$tskTrigger1 = $tskTriggers.Create(3);
$tskTrigger2 = $tskTriggers.Create(3);

## Trigger 1
$tskTrigger1.Id = "Trigger1"
$tskTrigger1.StartBoundary = (Get-Date -format "yyyy-MM-dd")+"T07:00:00";
$tskTrigger1.DaysOfWeek = 0x3E; # Monday - Friday - http://msdn.microsoft.com/en-us/library/windows/desktop/aa384024(v=vs.85).aspx
$tskTrigger1.Enabled = $true;

## Trigger 2
$tskTrigger2.Id = "Trigger2";
$tskTrigger2.StartBoundary = (Get-Date -format "yyyy-MM-dd")+"T12:00:00";
$tskTrigger2.DaysOfWeek = 0x3E; # Monday - Friday - http://msdn.microsoft.com/en-us/library/windows/desktop/aa384024(v=vs.85).aspx
$tskTrigger2.Enabled = $true;

# Principals (RunAs User)
$tskPrincipals.Id = "Author";
$tskPrincipals.UserID = "SYSTEM";
$tskPrincipals.RunLevel = 1;

# Actions
$tskActions.Context = "Author"
$tskAction1 = $tskActions.Create(0);

# Action 1
$tskAction1.Path = "C:\Windows\system32\vssadmin.exe";
$tskAction1.Arguments = "Create Shadow /AutoRetry=15 /For="+$volumeWMI.DeviceID;
$tskAction1.WorkingDirectory = "%systemroot%\system32";

# Configure VSS, Add scheduled task
vssadmin Add ShadowStorage /For=$Drive /On=$Drive /MaxSize=10%;
$tskFolder = $scheduler.GetFolder("\")
$tskFolder.RegisterTaskDefinition("ShadowCopyVolume$volumeID", $tskDef, 6, "SYSTEM", $null,5);
}

即使這可行，並且它模仿了您通過 GUI 執行此操作時發生的情況，但它仍然顯示為該驅動器已禁用。但是如果你啟用它，什麼都不會改變！（大聲笑）我猜在系統資料庫中還需要修改一些東西。
