Why incremental backup HDD to external hard drive?

Backup system or backup hard drive is the most common operation when you dealing with computer management. It is not uncommon to backup hard drive to external hard drive for better protection. While the question is all the drives has its size limitation. It is easily to fulfill the disk if you want to keep the backup images up to date. Therefore, incremental backup to external hard drive is a wise choice. While for better protection, you might need external hard disk backup software to back it up for a second time.

To get start, you need to know what incremental backup is. An incremental backup includes only those things that have changed since the last backup, and saves those things into a separate, additional, backup file or location.

The first backup of incremental backup is a full backup because there is no “previous backup” to compare to. The second incremental backup backs up only those files that have changes since that first backup was made, the third would backs up only those files that have changed since the second, and so on. To understand the definition is pretty important to make sure that you are appropriately backed up, yet not simultaneously eating up disk space at an exorbitant rate.
