Abstract
Various systems and methods for interval-controlled replication are described. For example, one method involves a node receiving a first interval indication indicating start of a first interval. After receiving the first interval indication, an application on the node initiates a first write, which includes the node initiating a first local write and a first remote write. The first local write accesses a local storage. The first remote write accesses a remote storage and replicates the first local write. The node waits for acknowledgements indicating that the local and remote writes have finished, as well as for a second interval indication, before the first write from the application is treated being complete.
