ABSTRACT:
Various embodiments may include taking an initial dump of a database table and tracking changes to the database table, with regard to but outside of transactions, since a most recent full or partial dump has been taken. A partial dump, in such embodiments, may be taken since the most recent full or partial dump and used to create a data structure which may be used to update only those database table rows modified since a last full or partial dump. As a result, the dumps of a database table will include a single full dump and may include one or more partial dumps. These full and partial dumps may then be instantiated to create or update an instance of the database table. In some embodiments, dumps may be taken directly to a mirrored instance of a database table.
