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. And the types of disk backup can be further divided into the following:
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: An external hard drive is independent of the operating system. The data stored on an external hard disk will not be affected by system errors, nor occupy the storage space of the local drive. It's also recommended to backup the external hard disk, 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.
Why do you need to create a disk backup
As for the use of hard drive backup, the biggest one should be data protection. No matter how much data is lost on any type of storage device for any reason, it can be easily and safely recovered from the backed up image files. What's more, there are several other usages as below.
💻Restore computer to previous good state.
It is necessary to make a disk backup after you purchase a new computer and install the operating system and applications. If the operating system or other data partitions has any problem, you can use the image file to get them back quickly, whether data or operating system.
💾Upgrade hard disk excellently.
It can upgrade a hard disk from old to new, small to large, damaged to good. The hard disk upgrading can help to solve the problem of low running speed result from "low disk space".
📂Assist in files restoration.
For many Windows users, they may have met the serious disk problem of system crash due to many reasons, such as, virus and hacker attack, hardware failure, wrong operation, software failure, natural disaster, etc. If the files in disk are lost, we can restore the lost files from the backup file.
Disk Backup vs. System Backup
Disk backup and system backup are two similar yet different concepts of creating backups of your computer's data and configuration. Let's explore the differences between them:
Disk Backup involves creating a copy of an entire disk, including system-related partitions and non-system data partitions. It contains all your data, files & folders, operating system files, settings, applications, and even the file system structure itself. Disk backups capture the exact state of the disk at the time of the backup, and they are particularly useful for disaster recovery scenarios where you need to restore the entire computer to a previous state.
System Backup focuses on creating backups of critical system files, settings, and configurations necessary for the operating system to function properly. It doesn't necessarily include all the data and applications present on the system, but it ensures that the core components required for system functionality are backed up. System backups are often more space-efficient than disk backups.
In summary, the choice between disk backup and system backup depends on your specific needs:
- Use disk backup if you want a comprehensive backup solution that captures everything on your disks, suitable for complete computer recovery in case of catastrophic failures.
- Use system backup if you're primarily concerned about the operating system and application configurations, and you're willing to perform separate backups for user data.
If you decide to create a disk backup in Windows 11/10/8.1/8/7/Vista/XP, please refer to the guide below.
How to Create A Disk Backup Step by Step

- Automatic cleanup: Create a retention policy by quantity, by time, by frequency to delete old backups automatically.
- Recovery environment: Create a boot option that allows you to one-key enter WinPE and perform backup/restore even when the system goes wrong.
- Dissimilar hardware restore: Restore Windows operating system to different hardware without boot errors.
