Screw me, my external hard drive crashed and now I am paying a company $200 to recover the data and transfer onto another HD. Should always keep 2 copies of everything, anyways.....should I use an external HD or a regular HD to back up files? What is more cost effective and safer?
I do have space on my computer to add another HD. But I am afraid if something happens to lets say motherboard, is the HD in danger?
External HD for backup is great, because you can detach it from the PC and store it separately. If you're really paranoid, keep it at your parents house or someone you trust nearby. Covers theft, fire, etc.
The external can be slower (if it's USB), a little more expensive, but the portability and separation is worth it IMO.
An optimal solution could be internal backup for ease/speed, schedule this daily or weekly. Use the external backup as a 2nd layer, do it every few weeks.
Online is a 3rd option, if you have some small/midsized but important files.
Nice thing about an external is that it will not have to run every time you start your PC like an internal would. Thus, you can connect it only when you need to recover/backup data and therefore it will have less wear and tear and last longer.
