[. . . ] Users access shadow copies with Windows Explorer by selecting View, Copy, or Restore from the Previous Versions tab. Both individual files and folders can be restored. 78 File server management Figure 23 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. NFSShare . @GMT-2003. 04. 27-04:00:00 . @GMT-2003. 04. 28-04:00:00 . @GMT-2003. 04. 29-04:00:00 HP ProLiant Storage Server 79 Access to NFS shadow copy pseudo-subdirectories is governed by normal access-control mechanisms using the permissions stored in the file system. Users can access only those shadow copies to which they have read access at the time the shadow copy is taken. To prevent users from modifying shadow copies, all pseudo-subdirectories are marked read-only, regardless of the user's ownership or access rights, or the permissions set on the original files. Server for NFS periodically polls the system for the arrival or removal of shadow copies and updates the root directory view accordingly. Clients then capture the updated view the next time they issue a directory read on the root of the share. Recovery of files or folders There are three common situations that may require recovery of files or folders: · Accidental file deletion, the most common situation · Accidental file replacement, which may occur if a user selects Save instead of Save As · File corruption It is possible to recover from all of these scenarios by accessing shadow copies. There are separate steps for accessing a file compared to accessing a folder. Recovering a deleted file or folder To recover a deleted file or folder within a folder: 1. Right-click, select Properties from the bottom of the menu, and then click the Previous Versions tab. Select the version of the folder that contains the file before it was deleted, and then click View. to allow the placement of the file or folder to a new location. 80 File server management Figure 24 Recovering a deleted file or folder Recovering an overwritten or corrupted file Recovering an overwritten or corrupted file is easier than recovering a deleted file because the file itself can be right-clicked instead of the folder. Right-click the overwritten or corrupted file, and then click Properties. to replace the current version with the older version, click Restore. Recovering a folder To recover a folder: 1. Position the cursor so that it is over a blank space in the folder to be recovered. Right-click, select Properties from the bottom of the menu, and then click the Previous Versions tab.
