    • Featured is a data storage back-up system for replication, mirroring and/or backing-up data including one or more first and second data storage devices that embody iSCSI, FC or alike principals and that are operably coupled to each other preferably via a WAN. The first data storage device is configured and arranged so there are two writes of data, one write to a persistent storage device from which reads are done and another write to a SAPS device wherein the data is saved using log-structured file system (LSF) techniques. After saving data to the First storage device, the data logs in the SAPS device are communicated to the second data storage device whereat a de-staging process is conducted so as to de-stage the data logs and write the de-staged data to a persistent storage device in the second data storage device.
    • 特色是用于复制,镜像和/或备份数据的数据存储备份系统,包括一个或多个第一和第二数据存储设备,这些数据存储设备包含iSCSI,FC或相同的主体,并且最好通过WAN可操作地耦合 。 第一数据存储设备被配置和布置成使得存在两次数据写入,一次写入到其中完成读取的持久存储设备,并且另一次写入SAPS设备,其中使用日志结构化文件系统(LSF)来保存数据, 技术 在将数据保存到第一存储设备之后,将SAPS设备中的数据日志传送到第二数据存储设备,在其中进行解除过程,以便对数据日志进行分段,并将去除的数据写入到 永久存储设备在第二数据存储设备中。
