Abstract
Various systems and methods for dividing, accessing, and sending portions of a data structure from one node to another for replication from a primary site to a secondary site are disclosed. The method includes dividing a data structure into portions. The data structure stores information identifying which regions of a data volume have been modified and nodes in a cluster share access to the data volume. The nodes and the data volume are located at the primary site. The method also includes sending a first portion of the data structure to a second node in the cluster. The sending causes the second node to replicate the data identified in the portion of the data structure from the data volume to the secondary site. In one embodiment, the accessing and the sending are performed by a logowner node.
