Abstract
A storage management device records write requests that are directed to a data store. In one embodiment, the storage management device records a plurality of write request entries, each one of which includes information relating to a write request, in at least one first database table, and maintains, for each first database table, at least one record in a second database table. The one or more records in the second database table include data representing the effects of the write requests on a state of at least one portion of the data store. In one such embodiment, each time that one write request entry is recorded in one first database table, the storage management device updates at least one record in the second database table.
