Backing up your files using NTBackup Utility

Click Start, Run and type NTBACKUP
Select Backup tab at the top
In the left pane, scroll to the file/folder which you want to backup and put a checkmark on it.
At the bottom, mention the output filename (the backup output)
Once set, click Start Backup button in the right, and again click Start Backup in resulting dialog


Note:
NTBACKUP does not have the ability to write to CDs directly. You will need to save the backup to hard drive, then transfer or burn it to a CD-ROM. Also, while backing up several files, make sure you backup the files in separate sets of each max 650MB (so that it fits on a CD-ROM)
