You can restore files with the Windows NT backup utility by doing the following:
1.Insert the backup tape into the tape drive. This tape should contain any files or directories that you want to recover.
2.Display the list of backup sets (called catalogs) on the tape by double-clicking on the tape's entry in the Tapes window or by selecting Catalogs from the Operations menu. The tape device will go out to the tape and find all of the available catalogs.
3.Using the right-hand pane of the Tapes windows, browse through the available catalogs. Double-click on a catalog to access its contents. Afterward, designate files and directories for recovery by selecting or deselecting their check boxes.
Tip The tape logs provide another way to find files you want to recover. These files are written as standard ASCII text and can be searched in a word processor, like any other text file. You can also use the Find feature of Windows NT Explorer as described in the "Searching by File Size and Contents" section of Chapter 9.
4.When you are finished selecting files, click the Restore button or choose Restore from the Operations menu. You can now specify how the selected files and/or directories are to be restored.
Note: The Restore button is only available when you are working with tapes or catalogs. Select a tape or catalog window to enable this option.
