How to block a user from copying files?

Question

System administration

In the office on the file server for each department there are folders for working with documentation. Access to them is restricted to employees. Each department head has full access to the folder of his department. Recently, one of them began to constantly create copies of existing directories and files. Talking about the fact that this is not necessary, since the volume of information amounts to hundreds of gigabytes and the space on the server quickly runs out, does not help. Are there utilities that, if there is a file or folder in the directory, forbid creating copies of it.

Answer 1

Set up a quota for departments. When the place for a particular department runs out, the manager himself will remove the excess.
Or try deduplication

Answer 2

Can he turn to higher management over a problematic employee?
Write a document describing the risks.
On linux, it would be possible to make a script that, through diff, compared the names of the files and if it found duplicates, it would delete them.

Answer 3

What a ridiculous approach.
Your organization can't afford to buy more disks or servers?
Sooner or later, the place will end anyway.
Get a good sysadmin.

Answer 4

I see some kind of version control system here. really try to teach users to work with it ....
or a file system with support for deduplication (I don’t know if there is such a thing under Windows).

Answer 5

Set up departmental quotas on the file server as advised by ldv .
For the character, offer to buy an external drive for a couple of terabytes and let him have fun. It is easier for management to justify such a move by the fact that server disks are significantly more expensive than a slut disk.
