I have configured file history backup on my windows 10 laptop to copy files from a drive partition to an external usb HDD drive.
In the Backup-options page when i click on backup now, it says backing up but nothing is actually backed up. Size of backup shows 0 bytes and i checked my usb hdd and i coudnt find my files there. All it has done is to create a folder named file history
Is the HDD drive working fine and properly formatted? Try copying a file to it manually and check if the drive is fine.
