SnapTrees & Security Models
Chapter 6 Share and File Access 47
SnapTrees & Security Models
Directories created at the root of a Snap Server volume are assigned one of two
security models: Windows or UNIX. The security model determines the file-level
security scheme that will apply to files, folders, and subdirectories within the top-
level directory. This security-based directory structure is referred to as a SnapTree.
• Creating a SnapTree Directory —
SnapTree directories are created either from the
Security > SnapTree
screens in the Administration Tool or from a client machine.
Using the SnapTree screens, you can assign either security model at creation
time. (The default is Windows.) Directories created from a client adopt the
security model of its parent volume or SnapTree directory.
Tip
A SnapTree directory can also be created and a security model assigned in
the course of creating a share.
• Toggling Security Models —
The security model applied to a volume or SnapTree
directory can be changed only from the
Security > SnapTree
screens.
Caution
Do not use spaces in naming a directory that is to serve as a share point.
The GuardianOS will recognize the directory, but it will not be available for use as a
mount point. Instead, use the underscore character to separate terms in a directory
name.
SnapTree Functionality
Function Description
SnapTree Directory Ownership Default ownership differs according to the method used
to create the SnapTree directory:
•
From the client — The logged-on user will be the
user owner of the directory, and the logged-on user’s
primary group will be the group owner of the
directory.
• From the Administration Tool — The user owner
of the SnapTree will be the admin account, and the
group owner will be admin group (admingrp).
Security Model Inheritance A volume is assigned a security model, and new
directories created at the root of the volume default to
that security model. Files and directories created below
a SnapTree directory default to its security model.
Toggling Security Models You can change the security model for an individual
volume, an individual SnapTree, or for a volume and all
the SnapTrees it contains.
Mixing SnapTrees You can create SnapTrees of different security models
on the same volume.
