Why incremental backup HDD to external hard drive?

System backup or disk backup is a normal way to protect your computer from system crashes or hard drive failures. And it is not rare to backup hard drive to external hard drive for better protection. The problem is that an external drive has its size limitation. It is easily to fulfill the disk if you want to keep the backup images up to date. In this case, incremental backup to external hard drive is a wise choice.

An incremental backup includes only changed or newly added data since the last backup, and saves them into a separate, additional, backup file. This undoubtedly saves your backup time and space (though requires a longer time for restoration).

In a nutshell, if you have a limited space of storage device yet want to make a backup of your system or hard drive regularly, then your can refer to the steps illustrated in the following article.
