Windows服务器的“系统状态”可以包含各种数据存储,但它总是包括注册表中的计算机设置,所以确保经常备份系统状态通常是一件好事。系统状态恢复通常可以修复注册表腐败(它确实对我来说,最近),虽然你需要记住服务器2008省略了用户注册表设置的系统状态备份,所以如果你有用户概要腐败,不可能被治愈的一个系统状态恢复。Server 2008没有用于系统状态备份的图形界面,但它通过工具WBADMIN (Windows backup Administrator)提供了命令行界面。创建系统状态备份的语法为“wbadmin start systemstatebackup -backupTarget:volumename”,其中volumename为目标驱动器。这里你遇到了一个问题。事实证明,Server 2008并不想让您备份到微软所谓的“临界容量”。系统卷和引导卷都是关键卷,当服务器上只有一个卷时,会出现问题。有一种方法可以解决这个问题,如Microsoft知识库文章KB944530所述,但是有足够的先决条件和警告,建议您使用不同的卷(例如,甚至是外部USB驱动器)来存储系统状态备份。另一个问题是,如果目标卷上的可用磁盘空间降至1 gb以下,WBADMIN可能会崩溃。微软还声明,目标容量应该至少是所需容量的两倍。 Whichever bit of advice turns out to be correct, err on the safe side. Also, be aware that you can’t specify the folder for your system state backup. WBADMIN uses a hardwired location under the WindowsImageBackup directory. Should you ever need to restore the system state, the command syntax is “wbadmin start systemstaterecovery –backupTarget:volumename -recoveryTarget:volumename” where "volumename" in each case specifies the appropriate drive letters. There are other command line options too. For example, if you back up multiple systems’ system state to the same location, use the –machine parameter to tell WBADMIN which one you want to recover. And if there are different versions, use the –version parameter to specify the date and time of the one you want. (The “wbadmin get versions” command will show you all the backups that exist on the volume.) If all this seems a lot more complicated than it should be – or than it used to be – then you have a lot of company! In fact, I would imagine that the only people who like this system seem to be the third-party backup software providers, who make their living improving on it.
