For anyone with this problem the way to use HCFileStorage.
The custom_zodb file should contain something similar to the following
import os,sys
import Globals
import ZODB.HCFileStorage
from Products.CMFOD.WebPage import WebPage
historyCategories = ('WebPage With History', [WebPage], 0),
storage = ZODB.HCFileStorage.HCFileStorage(Globals.BobobaseName,
historyCategories=historyCategories)
DB = ZODB.DB(storage)
Where WebPage is the context type for which I want to keep histories
for.
