I can help you with the global concept but no with a sample configuration
file, that's something you'll have to find out.
To setup quotas in samba you basically need setup two things:
- Enabling quotas for the mount point that holds the stored data (which
usually means installing "quota" and "quota tool" packages).
- Enabling samba quotas by configuring the corresponding samba VFS module.
(there are many guides and information on how to setup these two things on
the Internet...)
Remember that samba acts like a "glue" and knows little to nothing about
users/groups/filesystems and relays on "mapping" (linux → windows) to
mimic the Windows settings.

AFAIK, quotas can be applied to users/groups and to hard disk
volumes. What you can do in your case is restricting your user's quota
space and apply the restriction to the whole samba share volume. To get
this working well, you will have to play with users/grous permissions and
put special care in having a perfect mapping between samba (windows)
users/groups and your linux users/groups but still that can't be enough.
Another thing you do is discarding the use of quotas in the samba share
and monitor the available disk space in the linux volume, warning the
admin when the disk capacity reaches a defined percentage of use.
To make samba useful, what I usually do is keeping things as simple as
possible and create different directories for different purposes, for
instance:
- One (general) big pool directory where all users can read/write.
- Per user (specific) directories available only to their owners (kinda
private user dirs for their stuff).
- Hidden (non browseable) and protected directories where only root can
access to store, e.g., the bakcup files.
But designing and defining a good policy for samba to fit your network
requirements is not a simple task and requires high doses of trial and
error tests, fighting with users and permissions before you can put it
under production.

AFAICT, you need both.
