So i connected a new external 1TB hard drive to the server via USB. I used the Windows Server Backup program to configure that drive for scheduled nightly backups and after the software reformatted the drive all was set. After the first night it attempted to do a full system backup and it failed with Error Message (FAILED: Incorrect Function). I checkd c>windows>logs>windowsserverBackup there was no text log file created? I do see an ETL file created around the time of failure 1am. Event viewer shows Event ID 517 and that the backup failed about 7 minutes into it. Any reason why my backups are failing?
