SMB shadow copies
Windows users can independently access previous versions of files stored on SMB shares by using
the Shadow Copies for Shared Folders client. After the Shadow Copies for Shared Folders client
is installed on the user's computer, the user can access shadow copies for a share by right-clicking
on the share to open its Properties window, clicking the Previous Versions tab, and then selecting
the desired shadow copy. Users can view, copy, and restore all available shadow copies.
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 Open, Copy, or Restore from
the Previous Versions tab. (See Figure 15 (page 44)). Both individual files and folders can be
restored.
