Just an FYI. HP have released StoreOpen software for Windows (Linux and Mac already supported) for their LTO5 drives.
I'm only a brown-belt nerd and have been wrestling with backup software for LTO5. It's either been way too complicated or hasn't worked very well. StoreOpen effectively turns the LTO5 tape into a thumb drive so you can just drag n' drop files on/off it. Software is free and the tapes can be read by any LTFS software once you've copied your files to tape. Tapes store 1.5Tb without compression so it's a great way to archive my jobs.
