I'm using Windows, and I want to use Dropbox to back up a folder outside my Dropbox directory. So I want to create a junction point from my target directory to my Dropbox folder. According to the NTFS Junction Point article on Wikipedia, also linked from the Dropbox answer:
Junction points can only link to directories on a local volume; junction points to remote shares are unsupported.
I am looking to link to a directory on networked attached storage, which would not be a local volume, I believe. What should I do?
