Yes. I store in drives. In addition to that, I will be strong in another device also so that if one goes wrong the other may work. Many companies will also have the system of storing in two places so that there will not be any problem. Even today many companies continue the practice of keeping hard copies of important information. IT companies may not have that system. But they will store in 2 or 3 different gadgets based on the importance of the information. I have many flash drives in which I stored all the required information. In addition to that, I have an external harddisk also in which all the information is stored.
