+ 0 Votes USB Hard drive as backup device CG IT 3 years ago Like Justin, ran into the server detecting the USB drive and the backup software using it with scheduled, automatic backups. but, I still use the USB device as the backup source [use 2 identical devices]. I simply manually run the backups. One goes off site the other one stays onsite and we swap em once a week. It's an inexpensive alternative to tape if you can do manual backups.
