Even with modern electronics in the hard drives (spinning platter ones or the solid state ones), they normally fail to tell you in time when they go bad and believe me they do go bad.

Do note that while I have been discussing DATA back-up you will likely 
be wanting "systems" back-up also.

But are some BIG difference. You need to do DATA back-up frequently 
because your data is constantly changing. How frequently you need to be 
doing SYSTEMS back-ups depends on how you are allowing systems and 
programs to change. SOME of us allow "automatic upgrades" in which case 
your software is changing unpredictably. Others of us do "builds" and 
only change programs and systems at some definite time. We only need to 
back up systems and programs before a "build" and do not necessarily 
have to back up everything, just what was changed << but then we need to 
keep documentation>>

The second big difference is that we can LOSE data (that has changed 
since the last data back-up) but usually can replace software from where 
we got it in the first place. If you are NOT writing software, your need 
to back up programs is less <<but if we are writing programs, we better 
back THOSE up because there is no repository from which we could get 
them back>>

I do "builds", so only back up programs when some have changed. But what 
I write, I back up immediately upon completion (and the again any time 
in the future when I change them.
