A true cloud based "external drive"
I am a more advanced user being an engineer by trade, but I think you'll find this a valuable and detailed review of idrive.com. If you are looking for a true "external drive" type service. Not something that aims to sync your files across various devices, though idrive has that too, then idrive is your solution. I wanted to backup 8 computers. A mix of Windows PCs, home servers, Synology diskstations, and Macbooks. Only idrive had client apps for all of these platforms, as well as Linux. The home server had about 5TB (yes that's tera-bytes) of family photos and videos on it. This one took the longest. You need to understand that many internet service providers (ISPs) give you low upload bandwidth. In my case I have cable, 300Mbps down, but only 20Mbps up. That's 20 megaBITS per second. So 5TB will take about 23 DAYS to backup. Yes days. There is an iDrive Express option, where you can use a physical external drive as well though. Overall; the platform app coverage, the flexibility in how to treat my cloud backups, the ability to purchase a 10TB "drive" but use it to privately backup 8 different platforms, and reasonable annual cost, made iDrive a perfect fit for my needs. Give it a try, I think you'll find this is exactly what you're looking for if you want a "cloud drive".
