4.7.Shadow Copies for Shared Folders

Shadow Copies are accessed over the network by supported clients and protocols. There are two sets of supported protocols, SMB and NFS. All other protocols are not supported; this would include HTTP, FTP, AppleTalk, and NetWare Shares. For SMB support a client side application denoted as Shadow Copies for Shared Folders is required. The client side application is currently only available for Windows XP and Windows 2000 SP3+.

No additional software is required to enable UNIX users to independently retrieve previous versions of files stored on NFS shares.

Note

Shadow Copies for Shared Folders supports retrieval only of shadow copies of network shares. It does not support retrieval of shadow copies of local folders.

Note

Shadow Copies for Shared Folders clients are not available for HTTP, FTP, AppleTalk, or NetWare shares. Consequently, users of these protocols cannot use Shadow Copies for Shared Folders to independently retrieve previous versions of their files. However, administrators can take advantage of Shadow Copies for Shared Folders to restore files on behalf of these users.

4.7.1.SMB Access to Shadow Copies

Windows users can independently access previous versions of files stored on SMB shares via 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 dialog, selecting 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 of Shared Folders client pack installs a Previous Versions tab in the Properties dialog box of files and folders on network shares.
