There were several reasons to do data back-up. Learning from bank data security, on daily basis they’re doing it. For personal usage, usually some photos or video being back-up into blank DVD. The main purpose of doing it is to prevent data loss or just make some duplicate to be distributed to some friends or college.

The newest technology of storage disks are Blu-ray, un-scratch and last more longer. Although there were other storage with bigger capacities, but nothing can beat the size and efficiency of disks.

For file sharing such as data or family photos which are not that big, you could use blank CD as your storage. The benefit of cd/dvd other than its size and efficiency is its anti shock and though its fall, as log as there were no crack, the data inside it are able to be read.
