Qnap d2 vs WD my cloud ex2 Ultra?

Question

NAS

There was a question about purchasing a NAS for your home needs. I studied manuals for several days and looked at reviews on all kinds of NAS.
Now, as a result, there are 2 devices between which I can’t make the right choice. Qnap d2 and WD my cloud ex2 Ultra we need the opinion of the people who used these devices and would help make this difficult choice.
Ps First of all, the NAS is interested in the so-called "own dropbox", so that the necessary files are synchronized. And of course backup, which can be conveniently restored (both a separate file and the entire backup), and convenient access from different operating systems and devices to your NAS.

Answer 1

WD my cloud ex2 Ultra specifically makes an incremental backup (in fact, it's just a full backup), plus it's a hassle to install apt there.
