Backup and Restore are external commands that let you back up your hard disk onto as many floppies as required. Backup and Restore are not widely used, because you cannot Restore files onto a different PC that you backed up from a previous DOS version. Most people use the DOS Copy and Xcopy commands or use third-party backup programs for making backups. Backup and Restore were eliminated in Windows 95.
There are many backuping programs for Windows 95/98/NT/2000/XP/2003. Handy backup among them.
