Shares or group that has access to the root of a volume will have access to EVERY file and subdirectory on that volume unless there is a specific ACL in place precluding that access. In general, access to a share at the root of a volume should only be granted to a system administrator or backup operator. Hidden Shares A hidden share is hidden from clients connecting from the SMB, HTTP, AFP, and FTP (but not NFS) protocols. For example, assume SHARE1 is set as hidden. Windows users will not see the share when viewing the server through Network Neighborhood, or when performing a net view \\servername on the SnapServer. For more information, see "Configuring Share and Folder Security Overview" on page 96. Snapshot Shares A snapshot share provides access to all current snapshots of a volume. Just as a share provides access to a portion of a live volume, a snapshot share provides access to the same portion of the file system on any archived snapshots of the volume. You create a snapshot share by selecting the Create Snapshot Share check box in the course of creating or editing a share. Security Models, SnapTrees, and Shares In the course of creating a share that points to a volume or to a directory on the root of the volume (aka SnapTree directory), you must assign a security model to the volume or SnapTree directory. Thereafter, security models for these entities are managed on the Security > SnapTrees screens. NIS Users When a SnapServer is connected to a UNIX domain, NIS users do not appear in the list of users under Security > Shares > Access. NIS user properties cannot be modified from the SnapServer. However, it is possible to assign quotas to NIS users and groups from the Storage > Quotas page in the UI. To Set Up NFS Share Security Click the link in the NFS Access column next to the share you want to configure. The NFS Share Access screen displays. You can configure NFS access to the share using standard Linux "exports" file syntax. Note If selecting Create share with Admin-only access... and if the share has NFS enabled, be sure to configure the NFS Access settings afterward. 104 SnapServer Administrator Guide
