Existing methods are useful but limited

There are two common ways to back up the computer to an external hard drive. One approach is to use the built-in backup utility, which requires more patience because it will take a bit long time.

How long does it take to back up Windows 10 to an external hard drive

How long it takes depends on many factors, such as the amount of data to back up and the speed of the computer hardware. Typically, if your hard drive is HHD, a full backup of a computer with 100 GB of data takes approximately 1 to 2 hours. However, the same amount of system data can be done in 10 to 20 munites in the SSD device.

How to back up the computer when the PC fails to boot

If the Operating System cannot be accessed due to boot failure, you can still backup your data with the help of WinPE disk. You need to download and install iSumsoft Cloner on a working computer. Click Make a Boot Disk to create a WinPE bootable disk.
