Nfs Shadow Copies - HP StoreEasy 1000 Administrator's Manual

Figure 49 Client GUI
When users view a network folder hosted on the HPE StoreEasy 1000 Storage 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.
