I programmed my 20TB Synology RAID to back up all data to Amazon Glacier. It was simple and so far works great.
My Drobo FS NAS server was quickly running out of room and making noises. Time to upgrade to a newer NAS. I ordered in two Synology DS1515 5-bay NAS servers and proceeded to migrate 9 terabytes of data from my older non-supported DROBO NAS server to the much nicer and feature-rich Synology NAS server. An added bonus was the ability to set up Google Drive sync from my new server.
