backup from PC data drive to ReadyNAS

Any other suggestions?

My setup is not too dissimilar to yours.
Having being doing backups of one sort or another for many years, I have eventually settled on using RoboCopy.
This does all that I want and gives me control from the PC, with logs on the PC (which get backed up to NAS).
RoboCopy is easy to find online and is free and solves lots of problems, BUT you do need to read the manual carefully.
You will also have to write batch files of some sort, although these can be very simplistic.
I have ended up with a batch file that (currently) copies all of my 6 data virtual discs to another physical disc within the PC, then to an external disc via USB, then to the NAS in the garage room via the LAN, and then switches the PC off.
I just click this batch file before going to bed most nights, and it all happens. As only changes are copied across, it can be very quick and it is very reliable. But if it takes an hour who cares, I am in bed.
I am certain that other people are just as fanatical about their own particular backup strategy and 'tools' they use. My choice has given me a lot of control and flexibility, which is what I want. (I am a control freak) and my strategy has changed with time and technology, and will continue to change as things evolve.

I was thinking that you wanted a 'quick fix', hence the previous advice, although I am still not sure why the giving read access to 'everyone' does not work. Did you tick the box for the changed permissions to propagate through the sub folders? You MAY want to carefully consider why the files do not copy across at present BEFORE changing to some other strategy.
