    • The distributed computing backup and recovery (DCBR) system and method provide backup and recovery for distributed computing models (e.g., NoSQL). The DCBR system extends the protections from server node-level failure and introduces persistence in time so that the evolving data set may be stored and recovered to a past point in time. The DCBR system, instead of performing backup and recovery for an entire dataset, may be configured to apply to a subset of data. Instead of keeping or recovering snapshots of the entire dataset which requires the entire cluster, the DCBR system identifies the particular nodes and/or archive files where the dataset resides so that backup or recovery may be done with a much smaller number of nodes.
    • 分布式计算备份和恢复(DCBR)系统和方法为分布式计算模型(例如NoSQL)提供备份和恢复。 DCBR系统将保护从服务器节点级别的故障中扩展出来,并在时间上引入持久性,使得演进的数据集可以被存储和恢复到过去的时间点。 DCBR系统可以配置为应用于数据子集,而不是为整个数据集执行备份和恢复。 DCBR系统不需要保留或恢复需要整个集群的整个数据集的快照,而是识别数据集所在的特定节点和/或归档文件,以便备份或恢复可以用少得多的节点完成。
