686eeb11_s___Audit_trail_for_NHibernate__Description
[Property name] nhibernate.envers.store_data_at_delete [Default value] false [Description] 
Should the entity data be stored in the revision when the entity is deleted (instead of only storing the id and all other properties as null). This is normally not needed, as the data is present in the last-but-one revision. Sometimes, however, it is easier and more efficient to access it in the last revision (then the data that the entity contained before deletion is stored twice).
