Help with SMB permissions

[averagedad]

Hey all, I have an issue, I have a server with different datasets for different household members. What I want to do and need to know how is:

I want all users to have access to their own share but no access to any other, additionally I will need one admin account which has access to all shares for backup reasons.

I am new to truenas, so can someone please point me in the right direction and assist.

Many thanks
