Regular backups protect your data from hardware failures and honest mistakes, as well as from viruses and other malicious mischief. The Windows NT Backup utility is described in Chapter 6, “Backing Up and Restoring Network Files” in Microsoft Windows NT Server Concepts and Planning. For procedural information, see Help. Obviously, files must be read to be backed up, and they must be written to be restored. Backup privileges should be limited to administrators and backup operators—people to whom you are comfortable giving read and write access on all files.
