Nfs Shadow Copies; Client Gui - HP ProLiant 300 Series Administration Manual

Figure 31 Client GUI
When users view a network folder hosted on the storage server for which shadow copies are enabled,
old versions (prior to the snapshot) of a file or directory are available. Viewing the properties of the file or
folder presents users with the folder or file history—a list of read-only, point-in-time copies of the file or
folder contents that users can then open and explore like any other file or folder. Users can view files
in the folder history, copy files from the folder history, and so on.

NFS shadow copies

UNIX users can independently access previous versions of files stored on NFS shares via the NFS client;
no additional software is required. Server for NFS exposes each of a share's available shadow copies
as a pseudo-subdirectory of the share. Each of these pseudo-subdirectories is displayed in exactly the
same way as a regular subdirectory is displayed.
The name of each pseudo-subdirectory reflects the creation time of the shadow copy, using the
format .@GMT-YYYY.MM.DD-HH:MM:SS. To prevent common tools from needlessly enumerating the
pseudo-subdirectories, the name of each pseudo-subdirectory begins with the dot character, thus
rendering it hidden.
The following example shows an NFS share named "NFSShare" with three shadow copies, taken on
April 27, 28, and 29 of 2003 at 4 a.m.
