I'm asking a outsourcing developer to modify some part of my site and then he needs the copy of my site as a test site.
My site is already working site and has users registered. What comes in mind first is deleting user table from database to protect the personal information.
And the what else I should NOT give the developer? I trust the one who works on my site of course. But in generally is there any files or database table that can be harmful if the third party obtains?
