The Data Recovery utility is an interface available to the board administrator that allows the regeneration or recovery from pages that may have been corrupted. Various other board maintenance operations, such as reindexing the board and generating new thumbnails for user pictures, can also be accomplished through Data Recovery.

Although Discus Pro comes with many features that board administrators may want to try out, the features of Data Recovery should be used only when they are needed. This document provides a listing of all data recovery features, what they do, and when they should be used. Data Recovery features should generally not be used in other circumstances, as sometimes this can damage existing data.

As the old addage goes, if it ain't broke, don't fix it. Keep this in mind as you utilize the data recovery features.

Unless you really know what you're doing, you should start to see if your problem is on the following Symptom & Solution Guide.

• Symptom & Solution Guide: Describes the most commonly encountered problems and points you directly to the data recovery operation needed to resolve the problem.

Features of the tabs are explained on the following pages. Some of these recovery options are specific to Discus Pro and may not appear in the freeware version.

• Topics: Regenerate or rebuild the board topics page in the case of corruption or a failed import of previously created topics.

• Pages: Fix problems on pages, including any leftover problems from Discus 3.10 or before. Regenerate subtopic lists on specific pages that are known to be corrupt.

• Tree: Rebuild the board's "tree" files (i.e., reindex the board) if subtopic lists are not working properly.

• Search: Rebuild the board's search indexes, in the case that these have been corrupted or intentionally deleted in the process of moving a board. This is used as well if the "stop words" list has been changed.

• Upgrade: Run the version 3.10 to 4.0 upgrade procedure if this was not automatically run the first time you logged in to administration after upgrading to version 4.0.

• Other: Other miscellaneous data recovery utilities that do not fit well into the above categories are contained on the "Other" page.
