People do back up for specific reasons..
I think the primary ones are especially for “Formatting and reinstalling Operating System…” unless you do it at work.

I want to tell you something. If you want to back up a huge amount of files.. it’s better to compress it or use one of the back up solution programs, such as programs from Acronis (I know its not free..) or Norton.  You can still use the one that comes with Windows.

It’s very simple once you have any one of those kind.. but even if you do not have it.. You can still compress it. How to do it? click here for both Windows and Mac. Then why do we do it?? Why do we need to compress it?


Top 2 Reasons.


1. Secure –> You can encrypt it by putting some password. (Such as WinRAR(not free) or 7-zip(free) programs  support it).


2. Fast to back up.
Just like normal, it is always easier to carry in one big box. It’s a lot faster than carrying small boxes. The same rule also applies to computer. If you have so many little files, such as images or text files… I strongly recommend you to compress it before you do the backup.



Please don’t cry after you lose it. Always be prepared for any incident (or I should say accident) !
