Cloning is the process of creating an exact copy or clone of your data. It is often confused with backup but it is different from having a backup of your data. Cloning is the process of making a digital copy of your entire data. There are two main types of cloning.

  • Disk cloning is the process of copying the entire disk. All the data present on your drive including Windows, applications, files, documents, etc will be transferred to another hard drive or SSD. 
  • System cloning, on the other hand, is related to the system partition and system-related partitions. All the data that is essential for the system will be transferred in the system cloning.

Disk clone vs system clone; which one to choose? Let us give you a guide that will tell you what type of cloning is right for you.

The right kind of cloning for you depends on different factors. First of all, it depends on the files or you may say content you want to transfer. If you want to upgrade your drive, you want to go for disk cloning.

Disk cloning will allow you to migrate all the data from your current HDD to a new SSD. If you want to use the old operating system on the new drive, pick the option of system clone. If your drive has become full and there is no storage space left on it, you want to transfer your data to a disk with more storage capacity.

Sometimes you want to upgrade your hard disk and you may have to transfer your data to a smaller SSD. it depends on your requirements and preference for which cloning type you want to opt for.

System cloning is useful when users want to create a portable Windows USB. It would create exactly the same copy of your computer's system drive. With the same files and disk layout, you can run your own system on any other computer.
