Configuring Share and Folder Security Overview 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. 98 SnapServer Administrator Guide
