Abstract
Methods and apparatus are provided for consistency group replication with reduced resource consumption. An exemplary method comprises: obtaining, by one or more first replication appliances at a first location, one of (i) data generated by a monitored application; and (ii) metadata for each write operation generated by the monitored application, wherein a splitter function provides the data or metadata to the one or more first replication appliances based on a dynamic determination of whether the monitored application requires replication based on the data or the metadata based on predefined application consistency group type criteria; obtaining, by one or more of the first replication appliances, a snapshot comprising the data associated with each of the write operations since a prior snapshot based on the one of the data and the corresponding metadata; and providing the snapshot to one or more second replication appliances at a different location for storage in a replication journal.
