Why Do You Clone an External Hard Drive to Another

Many users choose to clone an external hard drive to another for backup purposes, which can help add an extra layer of protection to the external drive. You still have a duplicate copy if your external disk is damaged or lost. However, cloning an external drive and backing up an external disk are not exactly the same.

To back up an external drive means to copy files from one external hard drive to another. You will get a compressed image file; the system files can not be copied to another drive. Cloning a hard drive means your target disk will have everything the same as your source drive, including the data and disk layout. You may want to clone a hard disk for a variety of reasons.

• Migrating operating system. If you want to transfer an OS to a new hard drive, you can clone the old drive. Cloning can help you transfer everything from one hard drive to another.
• Creating a backup. Disk cloning can help create a fresh copy of your hard drive, which can be used as a backup in the event of hard disk failure or data loss.
• Transferring data from the old drive to a new computer. You can clone the old drive to the new one when using a new PC. Therefore, you can have your data and settings the same as the old drive.
• Drive upgrade. When you want to upgrade to a larger or faster drive, cloning helps transfer everything without the need to reinstall Windows, apps, or reconfigure settings.
