删除卷影复制副本，来找回你丢失的C盘空间

我的系统是Windows Server 2008 R2。最近c盘空间巨减。转念一想，也许是用磁盘清理可以弄走不少垃圾呢，不过试了半天还是不管大用。windows server 2008 r2与windows 7不同，首先服务器版系统没有系统还原，平时使用的是windows server backup，所以没还原多少空间。

不过，减少你磁盘空间的也可能是在windows server 2008 r2下开启的卷影复制功能。如下图：

开启卷影复制功能后，属性选项下就会有“previous versions”和"shadow copies“选项，具体设置与开启方式，可以参考下面我从帮助中截取的文字：

How do I enable and configure Shadow Copies of Shared Folders to make Previous Versions available?

Shadow Copies of Shared Folders is a feature included in the Shared Folders Microsoft Management Console (MMC) snap-in. If you enable Shadow Copies of Shared Folders on a volume using the default values, a task will be scheduled to create shadow copies at 7:00 A.M.. The default storage area will be on the same volume, and its size will be 10 percent of the available space.

You can only enable Shadow Copies of Shared Folders on a per-volume basis—that is, you cannot select specific shared folders and files on a volume to be copied or not copied. Also, you should not use this feature to create shadow copies of files needed for the operating system to run properly.

To enable and configure Shadow Copies of Shared Folders

1. Click Start, click Administrative Tools, and then click Computer Management.
2. In the console tree, right-click Shared Folders, click All Tasks, and click Configure Shadow Copies.
3. In Select a volume, click the volume that you want to enable Shadow Copies of Shared Folders for, and then click Enable.
4. You will see an alert that Windows will create a shadow copy now with the current settings and that the settings might not be appropriate for servers with high I/O loads. Click Yes if you want to continue or No if you want to select a different volume or settings.
5. To make changes to the default schedule and storage area, click Settings.

然后删除相关的备份点，即可释放很多空间，这个是无法从磁盘清理中删除的。

祝好。
