Are these database modifications just one time mods? I do not use VFP to make changes to the database. All my work on the database is done from SQL*Plus and script files. That way, if all is lost, I can re-create my database by re-running my script files. This will not replace any data, but I now have database documentation in these script files.

When I make changes to the tables, add new tables, create views, etc., I also include these changes in my script files.
