Windows Server Backup 佔用硬碟空間

在 Windows Server 2008 or Windows Server 2008 R2 的環境下，很多管理者使用 Windows Server backup 進行 AD 資料庫備份，時間久了之後，發現伺服器儲存空間幾乎滿了，但是實際使用空間卻很少(如圖所示)

 Windows Server backup 進行 AD 資料庫備份並非使用 NTFS 檔案格式，可以透過以下指令刪除舊資料，將空間釋放出來

例一 : 刪除第 61 之後的檔案 

Wbadmin delete systemstatebackup -backupTarget:b: -keepversions:60

 例二 : 刪除最舊的檔案

Wbadmin delete systemstatebackup -backupTarget:b: -DeleteOldest
