Abstract: Systems, methods, and computer-readable storage media for inter-node data replication while reducing network traffic for remote backup. A system receives a command to duplicate a dataset, located on a source network node, to a remote network node, accesses, on the source network node, signatures of a previous snapshot of the dataset and signatures of a current snapshot of the dataset, performs, at the source network node, a local signature comparison between the previous snapshot and the current snapshot to identify one or more signatures that do not match, sends the signatures that do not match to the remote network node, searches, on the remote network node, for the signatures that do not match, and sends data associated with the signatures that do not match to the remote network node for incorporation within a current remote snapshot if they do not exist on a current remote network node.

Abstract translation: 用于节点间数据复制的系统，方法和计算机可读存储介质，同时减少用于远程备份的网络流量。 系统接收到将位于源网络节点上的数据集复制到远程网络节点的命令，在源网络节点上访问数据集的先前快照的签名和数据集的当前快照的签名，执行 在源网络节点处，先前快照和当前快照之间的本地签名比较以识别不匹配的一个或多个签名，发送与远程网络节点不匹配的签名，在远程网络节点上进行搜索 ，对于不匹配的签名，并且如果它们在当前远程网络节点上不存在，则将与不匹配的签名相关联的数据发送到远程网络节点以合并到当前远程快照中。
