The usual approach to that kind of situation is to archive the files
you want to put on the NAS, using an archive tool that knows about
Linux attributes.

e.g. tar, tar.gz

You save the archive file to the NAS, attributes don't matter with the
archive file, itself.

Then on restoration, you fetch the archive file and unpack it (or
browse the contents), and the files inside the archive still have the
attributes you want.

I'm not sure what special attributes you're concerned about, though. 
If you're backing up personal data files, they don't tend to have
*special* attributes.
