Abstract: A write ordering style asynchronous replication service utilizes a loosely-accurate global clock in a data backup and recovery storage environment. The storage environment includes a set of source storage systems illustratively embodied as source replication nodes that cooperate to maintain a consistency group that may span multiple geographical sites. The storage environment also includes one or more target storage systems illustratively embodied as target replication nodes configured to service the consistency group. The write ordering style service utilizes the loosely-accurate global clock to provide consistent replication of a storage space of the consistency group.

Abstract translation: 写排序方式异步复制服务在数据备份和恢复存储环境中使用松散准确的全局时钟。 存储环境包括说明性地体现为源复制节点的一组源存储系统，所述源复制节点合作维护可跨越多个地理站点的一致性组。 存储环境还包括一个或多个目标存储系统，该目标存储系统说明性地体现为被配置为服务一致性组的服务器。 写排序样式服务利用松散准确的全局时钟来提供一致性组的存储空间的一致复制。
