Hard disk cloning refers to cloning all partitions of a hard disk and the files and other data in the partitions to another hard disk. If it is to clone the system disk, it will also clone the files and the boot partition needed to start the system.
During the cloning process, the cloning software will create partitions of the same size and type on the target hard disk according to the partition structure in the source hard disk. Then clone the files and data in each partition one by one. The cloned disk is fully operational. If the original disk fails, you can use the cloned disk to replace it.
When to Use Disk Clone
- Upgrade your hard disk, such as the upgrade to a bigger HDD or SSD
- Replace the disk when it is damaged, corrupted, or failing
- Clone system disk without reinstalling the operating system
The disk image is the process of making archives or backups of everything on the hard disk. Imaging creates a large compressed file of your drive. A disk image is a storage file that contains all the data stored on the source hard disk, as well as system boot information.
If you want this image to work, you need to put the image file on the hard disk and restore it with an image restoring tool. Unlike disk cloning, several disk image files can be placed on a hard disk. A disk image is just a file, so it can be stored on a USB flash drive, an external hard drive, or a cloud.
When to Use Disk Image
- Make backups of important files on your computer
- Make a backup of your system in case it gets damaged and your computer can't boot
- Transfer large amounts of data by creating a disk image and restoring
Disk cloning and disk imaging are two ways to achieve the same goal: both copy all the contents of a hard disk. But there are significant differences between the two. Disk cloning creates a one-to-one functional and uncompressed copy of the hard disk on another hard disk, while disk imaging creates an archive file of the disk, which can be used to make one-to-one copies.
The specific differences of clone VS image are as follows.
|Process||Make a one-to-one usable copy||Create a byte-by-byte archive as a compressed file|
|Efficiency||Run quickly for recovery||Only useful after being restored|
|Flexibility||Put one clone on a drive||Store multiple image backups on one drive|
