Translations:Manual:DeleteArchivedRevisions.php/3/en

When a page is 'deleted' by an administrator (Help:Sysop deleting and undeleting), records are moved from the 'revision' table to the 'archive' table, although the bulk of the data (page text) remains in the 'text' table. The script deletes all records from the archive table and then invokes $purgeoldtxt to purge the text records which no revision links to. This can be useful for reducing the size of the database but it does mean you lose the ability to restore the according revisions.
