My Cloud Home doesn't copy hidden files (that begin with a dot)

I decided to switch to a different NAS, as the MCH is barely usable in my case.
I inserted a USB HDD into the My Cloud Home and made it copy ‘All files’ through its web interface.
However, I just checked the copy and it appears that all files and folders that begin with a dot (i.e. hidden files in Linux distros) are missing in the copy.
I do understand that the MCH runs a Linux distribution and it ignores these files and folders on purpose, but it’d be nice if it were to actually copy everything.
