Yes, that's what the "distance overlay" means in the description. Usually these can be disabled if desired.

If you mean: "Does it backup periodically (you decide when) and only the new stuff on the hard drive, the answer is yes. It does not do a complete backup every time it backs up the system.

No, it does not. However, the one I bought failed in less than a year. Have Western Digital one that's been going strong for a few years now.

Yes. We have regular lines coming in to system. We had a professional come in and replace our old system but it was very quick and appeared to be easy.
