Just wanted to gather system administrators so we can share our thoughts and skills or even discuss on issue's we face everyday

Any one here work as a system admin professionally?
I have a small little question, i have this file server whereby its dedicated for a certain project. The thing is im having issue's about someone deleting certain folders used by senior management and these people are within the group. So i cant block these groups from accessing the folders.

I would like to know is there a 3rd party application that would show logs on who deletes content of a folder? Backup and restore can be done but i want to catch who is the culprit thats behind that.

Is there a way or tip that you could share??

Thanks a bunch
