Backup exec 2014 還原 Exchange 到 pst

之前要把Exchange上某個帳號的郵件從磁帶上還原時，已設定把還原的檔案放到D槽了，但在還原的過程中，C槽的資料量卻一直在變大，非常奇怪，後來查了一下，原來是在還原的過程中，磁帶裡的備份檔會先全部暫存到C槽下，但真正要還原的郵件資料還是會丟到原本指定的地方。所以在還原時要注意C槽的容量夠不夠，或是更改暫存檔的存放路徑，設定的地方請參考圖片。

Requirements:

1. The Backup Exec Agent for Microsoft Exchange must be present on the media server (an evaluation edition of BE and/or the agent can also be used), and the Remote Agent must be installed on the destination server to which the mailbox or public folder items are being restored to.
    
2. In the restore job selections, the mailbox or public folder items must show as being available to restore. Databases cannot be redirected to PST.
    
3. Microsoft Outlook 2003, 2007, or 2010 (32-bit only) must be installed on the destination server.
    
4. If the backup is on tape, Backup Exec will stage the entire backup set to a local drive on the Media server, so please ensure that you have enough space on a local drive. Note: By default, the staging path is C:\temp. The path can be changed from the Backup Exec Settings-Granular Recovery Technology option screen.
