Patent ID: 7885923

Claim:
A method, comprising: a plurality of nodes in a distributed computing environment sending write requests to a primary temporal volume and replicated write requests for the temporal volume to a replication target device, wherein the temporal volume is configured to store temporal data, wherein each replicated write request is a copy of a corresponding one of the write requests, wherein each of the replicated write requests is associated with an indication of a timestamp for the temporal data on the temporal volume, and wherein the replication target device is configured to generate a checkpoint of the temporal volume corresponding to the timestamp; initiating a consistency interval transition, wherein the consistency interval transition defines a point in time at which data on the temporal volume is in a consistent state, and wherein the consistency interval transition corresponds to the timestamp; in response to the initiation of the consistency interval transition, each of the plurality of nodes: temporarily suspending sending replicated write requests to the replication target device; and subsequent to said temporarily suspending, resuming sending replicated write requests to the replication target device, wherein an indication of a second timestamp is associated with each replicated write request sent after said resuming.
