What is Disk Backup?

When carrying out the operations of hard disk backup, all the data, operating system, programs will be backed up to an image file, which can be used for disk restoration when it is necessary. As for the category of disk backup, it includes several types:

  • MBR/GPT disk backup: Under a certain rule, the disk can be classified into MBR and GPT disk. The biggest difference between the two is that MBR disk only supports disk less than 2TB, while GPT disk supports disks larger than 2TB.

  • External disk backup: With the popularity of computer, some external hard disk has also attracted so much attention from users. Many people store their important or accidental information on their external hard disk. For example, many game enthusiasts would store all their games on an external hard drive so as not to occupy the storage space on the hard disk. In this case, the external hard disk should be backed up completely beforehand, preferably on a regular basis.

  • Backup of hardware RAID: RAID is short for "redundant array of independent disks". It is a storage technology that includes multiple hard disk drive components. Each logical hard drive of the RAID should be backed up due to its vast amount of data and files.
