Make a copy of a file when someone tries to modify the file

I wish to take a backup of the file when someone tries to modify a file say /tmp/test.txt using vi, vim, cat, copy, mv commands.

I'm aware of inotify which will notify me of any changes to the file however, I wish to make a backup before and not after the changes are made to the file.

I wish to avoid loop check and backup on the file as i believe it will be too time consuming.

Thus, whenever someone makes changes to a file there should exist its backup taken right before the file is modified.

Can you please let me know if and how this is possible to achieve ?

A solution that works across AiX / Linux systems would be great.
