My laptop is running out of storage and I need to add external storage. I also use Backblaze backup, they support physically attached devices like USB, Firewire & Thunderbolt but they do not backup NFS drives. I find I move around a lot more that I thought and the USB disk is attached to a thunderbolt hub and most of the time I don't unmount the USB disk properly before running off with the laptop. So I'm looking for a solution of sorts which will allow me to just unplug the storage (Like NFS). But something which will also work with my backup vendor.
