Abstract
Systems and methods are provided for an asynchronous data replication system in which the remote replication reduces bandwidth requirements by copying deduplicated differences in business data from a local storage site to a remote, backup storage site, the system comprising: a local performance storage pool for storing data; a local deduplicating storage pool for storing deduplicated data, said local deduplicating storage pool further storing metadata about data objects in the system and which has metadata analysis logic for identifying and specifying differences in a data object over time; a remote performance storage pool for storing a copy of said data, available for immediate use as a backup copy of said data to provide business continuity to said data; a remote deduplicating storage pool for storing deduplicated data; and a controller for synchronizing the remote performance storage pool to have the second version of the data object using deduplicated data.
