I am new to this and have very basic knowledge about web servers. I had my server created as a backend for an mobile app. It is now working fine.
However, I am now working on a new version for the app and have hired a new developer. This developer needs to have access to the server to see how this is set up.
My questions: Is there a way to give him read access only, instead of granting full root access?
How do I make a backup copy of my server, so just in case this new developer messes something up, I can always recover my files?
Any help would be extremely appreciated.
