NTBackup，内部称为 Windows 备份实用程序（Windows Backup Utility），也称为备份实用程序或简称备份，是 [[Microsoft Windows 通述|Microsoft Windows]] 中的备份工具。它可以在软盘或磁带驱动器上创建文件和系统备份。

== 历史 ==
=== 早期版本 ===
NTBackup 最初包含在 [[Windows NT 3.1]] 中，作为 Windows NT 操作系统的恢复解决方案。它在内部被称为 NT Tape Backup Utility（NT 磁带备份实用程序），顾名思义，它是一个可以在磁带驱动器上创建文件备份的程序。启动时，它有一个简单的界面，可以打开一个窗口，可以在其中浏览连接到计算机的磁带驱动器以搜索现有的备份文件以管理它们或在其上创建一个新文件。

=== Windows 2000 ===
NTBackup 的首批显著改进是在 [[Windows 2000]] 中出现的，其中包括以下更改：

* 界面进行了一次重大改革，其中删除了子窗口功能并分为不同的向导和选项卡。
* 除了磁带驱动器之外，软盘现在还可以用作备份设备。
* 引入计划作业（Schedule Jobs）功能，它允许在特定的磁带驱动器上创建不同的 “jobs” 或定期备份。
* 紧急修复磁盘（Emergency Repair Disks，ERD）创建已从 [[Windows 安装程序]]和 <code>rdisk</code> 工具（在此版本中删除）迁移到此应用程序。但是，ERD 可以与[[恢复控制台]]互换使用，恢复控制台已添加到此版本的 Windows 安装介质中，并具有类似的恢复功能。

Windows 2000 最初也计划提供 Automated System Recovery（自动系统恢复）功能。它首先在 [[Windows 2000 Build 1575.1|Build 1575]] 中作为 Disaster Backup Recovery（灾难备份恢复）添加，后来在 [[Windows 2000 Build 2031.1|Build 2031]] 中删除并推迟到 Windows XP。

=== Windows XP and Server 2003 ===
[[Windows XP]] and [[Windows Server 2003|Server 2003]] had additional improvements which included the following:

* The tool's icon has been changed to reflect the addition of floppy drive support. The internal name has also been changed to ''Windows Backup Utility'' to be more generalized.
* A new visualization, the ''Wizard Mode'', has been added and shows up by default when launching the tool, which contains more simplified options. The untouched Windows 2000 interface is now referred to as the ''Advanced Mode'', and can be launched in place of the Wizard Mode through a link on its initial screen.
* Support for Emergency Repair Disks was dropped.
*The Automated System Recovery feature has been reimplemented and finalized.
* The Restore tab in Advanced Mode has been renamed to ''Restore and Manage Media''.

=== Replacement ===
In [[Windows Vista]] and [[Windows Server 2008|Server 2008]], new tools were included as a replacement for NTBackup, these being [[Backup and Restore]] and [[Windows Server Backup]], respectively. They included backup support in more drive types, such as CD-ROM, or even other hard disk drives, and included separate solutions that provided more control over system-state backups. Other features NTBackup had were also kept, such as scheduled backups. However, the ability to back up on tape drives was removed.
