A system for loosely coupled temporal storage management includes a logical storage aggregation including a plurality of data blocks, a data producer, one or more data consumers, and a temporal storage manager. The temporal storage manager may be configured to maintain a producer shadow store including entries stored in a log-structured logical volume, where each entry is indicative of one or more data blocks of the logical storage aggregation that have been modified by the data producer. The temporal storage manager may also be configured to maintain a repository containing a baseline version of the logical storage aggregation, and to provide the data consumers with read-only access to the producer shadow store and the repository.
