Abstract
A node for use in a data management system includes a persistent storage and a data protection agent. The persistent storage stores data. The data protection agent makes an identification of a data protection strategy change event for the data; in response to the identification: makes a determination that the data protection strategy change event is a scale down event; in response to the determination: identifies a number of replicas of the data in other nodes that are in a predetermined state; makes a second determination that the number of the replicas of the data in the other nodes that are in the predetermined state exceeds a threshold specified by a data protection policy associated with the data protection strategy change event; and reduces the number of replicas that exceed the threshold to be less than the threshold in response to the second determination.
