Why Is It Necessary to Backup C Drive to External Hard Drive

C drive is what we called the "system drive". The computer's booting problem is usually resulting from system data error or system drive error. If users just simply move the system data to other places, it is very likely that the machine cannot boot properly, or some programs cannot run as usual. The operating system and applications can be reinstalled, but it may be difficult or impossible to recreate your system files. So a C drive back up to the external hard drive is a good choice. 

For one thing, an external hard drive is easy to use, portable, and increasingly cheap. You just need to plug it into a computer using USB port when you need to back up and pull it out when all the operation is done. For another, once the backup is done and the external hard drive is disconnected, your data is not affected by the computer. It is an efficient way to protect your data security.
