Data backup

This is the most important step for maintaining the security of important data. very often computer users have an unerring faith in computer storage media. there are regular instances of people entrusting their only copy of a thesis or dissertation to single floppy disk. it is a fact that all forms of magnetic media degrade over time and will ultimately fail. there is far less certainity as to when a disk will fail or what the consequences might be. therefore you should save your work regularly and not to the same storage devce. backup frequency depends upon how much data you have and how regularly it changes. as a guideline, if you could not bare to loose something, it is time to make a copy. choosing an alternative location is eminently sensible or your backup will suffer the same demise as the original. whatever else may happen, if your data is kept on a media other than the hard disk of your computer you will be able to recover it. written by: sohail imdad IT profesional
