Chapter 5.7. Protecting Data > Backup and Restore

Backup and Restore

The backup program used by Windows NT did not change from version 3.1 through version 4.0. Windows NT's scheduling service (sometimes called the AT service) was one of the few things left in the operating system from OS/2. Windows 2000 has a new backup program (although it is still called NTBACKUP.EXE and supports the old command-line switches to aid migration) and a new scheduling service (although the new schedule service can be add to Windows NT 4.0). The functionality of the RDISK program that Windows NT 3.5 and 4.0 used has been transferred to the backup program.

The backup program can store data on tape or to a file, which can be stored on a hard disk, floppy disk, or network drive. It can be started by calling up the properties for a disk volume and clicking Backup Now on the Tools page, from the Start menu (by default under Accessories, System tools), or from a batch file or command line—including running it as a scheduled task.
