    • Methods, apparatus, and computer-accessible storage media for shadowing data stored on a local store to a remote store provided by a service provider. A gateway may be configured as a Methods, apparatus, and computer-accessible storage media for shadowing data stored on a local store to a remote store provided by a service provider. A gateway may be configured as a shadowing gateway on a customer network in response to receiving configuration information. The shadowing gateway may receive reads and writes to the local store. The gateway passes the requests to the local store, and also uploads write data indicated by the writes to the service provider to update a snapshot of the local store maintained by the service provider on the remote store. The write data may be buffered to a write log for uploading, and may be uploaded as blocks according to a block storage format used by the service provider. The shadowing process may be transparent to processes on the customer network. The shadowed data may be used to recover data on the local store.
    • 方法,装置和计算机可访问的存储介质,用于将存储在本地存储器上的数据映射到由服务提供商提供的远程存储器。 网关可以被配置为方法,装置和计算机可访问的存储介质,用于将存储在本地商店上的数据映射到由服务提供商提供的远程商店。 响应于接收配置信息,网关可以被配置为客户网络上的遮蔽网关。 阴影网关可以接收对本地商店的读取和写入。 网关将请求传递到本地商店,并将写入指示的写入数据上传到服务提供商以更新由远程商店上的服务提供商维护的本地商店的快照。 写入数据可以被缓冲到用于上传的写入日志中,并且可以根据服务提供商使用的块存储格式作为块上传。 阴影过程对客户网络上的流程可能是透明的。 阴影数据可用于恢复本地存储上的数据。

    • Methods, apparatus, and computer-accessible storage media for remotely updating an executing process that receives I/O requests on I/O port(s), stores write data to a write log on local storage, and uploads data from the write log to remote storage. An update for the process is detected and downloaded, and an updated process is instantiated from the update. The current process is directed to perform a shutdown for update during an update window. In response, the current process saves its current configuration, flushes an in-memory portion of the write log to local storage, and releases its I/O port(s). The updated process loads the saved configuration, detects that the port(s) have been released, and starts accepting I/O requests on the ports. During flushing, the current process flushes current data in memory while continuing to append new write data, stops accepting new write requests, and then flushes the new write data.
    • 用于远程更新在I / O端口上接收I / O请求的执行过程的方法,设备和计算机可访问的存储介质将写入数据存储到本地存储器上的写入日志,并将数据从写入日志上传到 远程存储。 检测并下载该过程的更新,并从更新中实例更新过程。 当前进程被指示在更新窗口期间执行关闭更新。 作为响应,当前进程保存其当前配置,将写日志的内存部分刷新到本地存储,并释放其I / O端口。 更新的进程加载保存的配置,检测端口已被释放,并开始接受端口上的I / O请求。 在刷新期间,当前进程刷新存储器中的当前数据,同时继续追加新的写入数据,停止接受新的写入请求,然后刷新新的写入数据。
