Log shipping to fix unintended deletion?
Because the database at the DR site is in read_only mode, you can export the data from the DR table where the deletes occurred on the primary and 'repopulate' the primary server for just that one table using the data exported from the DR site.  This would be especially useful if the database is extremely large, because you would not have to restore the entire database to get just that one table recovered.
This, of course, assumes the log records containing the deletes have not been applied to the DR database.
