Why backup Windows 10 to USB flash drive?

We all know system backup is very critical. If your system crashes due to virus, hard failure or human error, you can restore it to its previous state using a system backup image. However, choosing a reliable location to save the image files is even more important. The reasons to run Windows 10 backup to USB are as follows.

1. Keep image files away from computer errors.

If you save your backups to an internal hard drive, you may lose the backups if hard failure happens. Some people may choose to backup to NAS (network-attached storage). However, if many users have access to the shared location and it is always connected, virus and malware may also infect the shared folder.

Therefore, it is recommended to backup to an external hard drive, like a USB drive. It is safe for your data because a USB flash drive can be stored in a location that’s separate from your computer once the backup is done. You can also clone the USB drive to another drive with free USB clone tool for extra protection.

2. Easy access on other devices.

If you want to use the image files on other computers, you can easily connect USB drives to the computers via USB ports. To restore a system image to a computer with different hardware, you need to perform dissimilar hardware restore to ensure the system is bootable after recovery.

3. Strong endurance.

A USB flash drive is always very tough. It is not likely to be damaged unless you hit it with a hammer or something else.

Built-in backup tool to backup to USB in Windows 10

USB flash drive is a good file transfer tool as well as a great storage location for backup images. When it comes to backup Windows 10 to USB, many PC users would like to use Windows Backup and Restore.

However, when you choose USB flash drive as the backup destination at the step of “Where do you want to save the backup?”, you will see a warning that reads: “The drive is not a valid backup location”. This problem also happens when you use Backup and Restore in Windows 7/8. (In Windows 8, the tool is called Windows 7 File Recovery.)

Create a System Image

It is a default limitation that Windows users cannot save system drive image to USB flash drive. In earlier times, USB flash drive was created in small size. Therefore, it is hard and insecure to place a system backup image which is up to several GB in size on a flash drive, especially when scheduled system backup is set.

Now you can get a USB drive with large capacity. To save a system image, the available storage space on USB should be at least 64GB. However, a 64GB USB is not suggested because the actual space is less than 64GB. Therefore, it is recommended to buy a 128GB USB. When you use a 128GB USB, you will not see this warning again.
