Plugged in an external HDD (Western Digital My Passport Essential 500 GB USB 3.0/2.0) into the back of the unit, logged into the web interface, went to System, Storage, selected the external drive to format, selected xfs and clicked on format.
After formatting, navigated to Shared Folders, Folder Setup, verified Disk Backup is checked for USB Disk1 and other Shared Folders that are to be backed up to the external dive. Navigated to System, Backup, Backup Jobs, clicked Create New Job, selected backup schedule Immediate and Normal Backup. Clicked Add in the Backup Folders, Selected backup source ie my other shared folders, selected backup destination, hit Add, then Apply.
3 hours later it has only backed up 45.8GB out of the 252 GB, then backup job tells me an error has occurred. Where would one go to find a description of the error?
