What is the mirror?

Mirroring is a form of file storage and a type of redundancy. The data on one disk has an identical copy on another disk, which is a mirror. You can make many files into a mirror file, put it on the same disk with programs such as GHOST, and open it with software such as GHOST, and then restore it to many files. RAID 1 and RAID 10 use mirroring. Common image file formats include ISO, BIN, IMG, TAO, DAO, CIF, and FCD.

Overview

The so-called image file is actually similar to a ZIP compressed package. It makes a specific series of files into a single file in a certain format to facilitate users to download and use, such as a beta version of an operating system, game, etc. The image file not only has the "synthesis" function of a ZIP compressed package, but its most important feature is that it can be recognized by specific software and can be burned directly to a disc.

In fact, the image file in the usual sense can be expanded and contain more information.

For example, system files, boot files, partition table information, etc., so that the image file can contain all the information of a partition or even a hard disk. The classic software that uses this type of image file is Ghost. It also has a burning function, but its burning only saves the image file itself on the disc. In general, burning software can directly save the image file contained in the supported image file. Content is burned to disc.
