Mirror backup vs. mirror image backup

Doing a mirror backup is to duplicate certain files and folders from one place to another. It is the fastest backup method because it doesn’t require any compression of the source data. The other advantage of a mirror backup is that the backed data can be used directly without the restoration process.

Apart from mirror backup, another commonly-used backup method is mirror image backup. You can create a mirror image backup for the operating system, a hard disk, a disk partition as well as individual files/folders. The backup process will generate an image file and the file type of the image file is usually proprietary to the backup program that's being used.

The following table will show you the differences between mirror backup and mirror image backup more clearly:
