Shadow Copies for Shared Folders preserves the permissions set in the access control list (ACL) of the

original folders and files. Consequently, users can only access shadow copies for shares to which they

have access. In other words, if a user does not have access to a share, he also does not have access to

the share's shadow copies.
The Shadow Copies for Shared Folders client pack installs a Previous Versions tab in the Properties

window of files and folders on network shares.
Users access shadow copies with Windows Explorer by selecting View, Copy, or Restore from the

Previous Versions tab. (See

Figure 12

). Both individual files and folders can be restored.

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 [email protected]: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.
