Abstract: The illustrative systems and methods use a special-purpose volume-replicating server(s) to offload client computing devices operating in a production environment. The production environment may remain relatively undisturbed while production data is replicated to a geographically distinct destination. Replication is based in part on hardware-based snapshots generated by a storage array that houses production data. The illustrative volume-replicating server efficiently moves data from snapshots on a source storage array to a destination storage array by transferring only changed blocks for each successive snapshot, i.e., transferring incremental block-level changes. Periodic restore jobs may be executed by destination clients to keep current with their corresponding source production clients. Accordingly, after the source data center goes offline, production data may be speedily restored at the destination data center after experiencing only minimal downtime of production resources. By employing block-level techniques, the disclosed solutions avoid the file-based data management approaches of the prior art, which tend to be too time-consuming and resource-intensive for the present scenario.

Abstract: A log monitoring system uses log monitoring rules to monitor log data generated by applications executing on a client computing device. By monitoring log data, the system detects that one or more triggering events have occurred on the client computing device. In response, the log monitoring system can perform one or more appropriate remedial actions. Additionally, in response to the detected event(s), the log monitoring system can extract a select subset of relevant data from the client and transmit the subset of data to a separate repository for storage and/or processing.

Abstract: Systems and methods are provided which perform a file level restore by utilizing existing operating system components (e.g., file system drivers) that are natively installed on the target computing device. These components can be used to mount and/or interpret a secondary copy of the file system. For instance, the system can instantiate an interface object (e.g., a device node such as a pseudo device, device file or special file) on the target client which includes file system metadata corresponding to the backed up version of the file system. The interface provides a mechanism for the operating system to mount the secondary copy and perform file level access on the secondary copy, e.g., to restore one or more selected files.

Abstract translation: 说明性的系统和方法使用专用卷复制服务器卸载在生产环境中运行的客户端计算设备。 当生产数据复制到地理上不同的目的地时，生产环境可能保持相对不受干扰。 复制部分基于由容纳生产数据的存储阵列生成的基于硬件的快照。 说明性的卷复制服务器通过仅传送每个连续快照的改变的块，即传送增量块级改变，将数据从源存储阵列上的快照移动到目的地存储阵列。 目标客户端可以执行定期还原作业，以保持与其对应的源生产客户端的最新状态。 因此，在源数据中心离线之后，生产数据可能在经历仅生产资源的最短停机时间之后可以在目的地数据中心被快速恢复。 通过采用块级技术，所公开的解决方案避免了现有技术的基于文件的数据管理方法，其对于本方案往往过于耗费时间和资源。
