I set the path to drive E, but I did not specify the folder after that. E drive I do not know if it is created as a folder with a name and it is a backup. And there are too many files that backup failed. I do not know why.
Hi chpark,
WD Backup will not backup files that are locked or in use by the Windows operating system, running software, programs or processes. You can have a look on below KBAs for more details:
