We need to backup the files in our system at times and the image is stored on an external drive. Many users prefer an external Hard Drive which some prefer a USB drive.
Earlier USB drives didn’t have enough space (eg. 64GB for a system image), thus that device was neither permitted nor usable for backing up system data. Some users have reported that despite their USB drive having sufficient space, they get the following error:
The drive is not a valid backup location.
Thereafter, proceed with the following solutions:
Solution 1 – Sharing the drive
1 – Open Run by pressing Windows and R key at once
2 – Type diskmgmt.msc in it and click OK
3 – Now, Locate the drive in which you want to create the backup and getting this error.
Right click on it and click properties
4 – Click on Sharing Tab
5 – Click on Advanced Sharing
6 – Select share this folder

15 – Click on Create a System image
16 – Select On a network location
