Abstract
A first agent informs a second agent that a backup file is created for an active copy of a data object in a first node in a cluster of nodes, in response to the first agent determining that the backup file is created for the active copy of the data object in the first node. The second agent instructs a change tracker associated with a passive copy of the data object in a second node in the cluster of nodes to begin tracking changes received from a synchronizer associated with the active copy of the data object in the first node, wherein tracked changes received from the synchronizer associated with the active copy of the data object in the first node enables a next backup operation performed on the data object to be performed as an incremental backup operation on the data object in the second node.
