Just their MyCloud hard drive + syncthing has been my ideal backup solution for all my devices for about 5 years now. Any document I save on any of my device instantly gets replicated onto all my devices. Any picture/video i take on my phone gets backed up to my NAS automatically. I used to host a browser based file manager and had dynamic dns pointing to that NAS for the rare use case where i wanted to share a file with someone via a link.
Such a shame I'll have to re do all this set up if/when i need to move away from that drive...
