■ Snapshots are created on a per volume, partition, or logical drive basis.
■ Snapshots can be read-only, read-write or always keep.
■ Snapshots are mounted as a mount point on the root of the volume, partition
or logical drive.
■ Snapshots can be shared in the same manner as any other folder, drive or
mount point.
■ Snapshots are meant to be temporary in nature.
■ Snapshots are automatically deleted if disk space becomes critical and they
are not set to always keep.
■ Persistent Storage Manager only writes to the cache file on the first change of
the underlying data.
Full documentation of Persistent Storage Manager may be found in Chapter 6 of
the administration guide.
File system elements are composed of the folders and subfolders that are created
under each logical storage element (partitions, logical disks, and volumes).
Folders are used to further subdivide the available file system providing another
level of granularity for management of the information space. Each of these
folders can contain separate permissions and share names that can be used for
network access. Folders can be created for individual users, groups, projects, etc.
Refer to the administration guide for more details on file system elements.
The NAS b2000 v2 supports several file-sharing protocols, including CIFS, NFS,
FTP, HTTP, NCP, and AppleTalk. On each folder or logical storage element,
different file sharing protocols can be enabled using specific network names for
access across a network to a variety of clients. Permissions can then be granted to
those shares based on users or groups of users in each of the file sharing protocols.
Refer to the administration guide for more details on file system elements.
