Configuring Share and Folder Security Overview
98 SnapServer Administrator Guide
event that permissions on a child directory are inadvertently altered to disallow
administrative access, access from the root share is not affected. This also allows one
root share to be targeted when performing backups of the server. If it is necessary to
have the root of the volume accessible, using the Hidden option helps ensure only
those that need access to that share can access it.
SnapTrees
SnapTrees are directories that can be configured for the Windows/Mixed or UNIX
security model. SnapTrees make a specific directory structure follow the rules of the
specified security model, which indicates which file permission personality will be
present on files by default, and whether that personality can be changed by users
when changing permissions. All top level volume directories, as well as all
directories inside the first level of a volume, are considered SnapTrees. For more
information, see “SnapTrees and Security Models” on page 100.
NFS Share Access
When controlling share access for NFS clients, administrators can limit client access
to the shares independently of share level permissions that apply to other protocols.
Access is controlled on a per-share basis. To set the NFS access, navigate to
Storage > Shares
. In the Shares table, click in the
NFS Access
column of the share
you want to modify. Changes made on this screen affect the NFS “exports” file
within GuardianOS.
Caution
If there are multiple shares to the same directory on the disk, and those
shares permit access via NFS, they must all have the same NFS export
configuration. This is enforced when configuring NFS access to the overlapping
shares.
