If the table definitions are the same, you should be able to use
mnesia:restore/2 to copy the contents of all/some of the tables. If
you want to make sure that dbB is always an exact copy of dbA, then
you can rename the nodes in the database backup you take from dbA (see
example in mnesia user guide), and then do an mnesia:install_fallback.
