    • Exemplary storage network architectures, data architectures, and methods for creating and using snapdifference files in storage networks are described. One exemplary method may be implemented in a processor in a storage network. The method comprises detecting a failure in a source volume, and in response to the failure: terminating communication with one or more applications that generate I/O requests to the source volume; refreshing the source volume; copying a backup data set to the source volume, and while the backup data set is being copied: activating a new snapdifference file; restarting communication with one or more applications that generate I/O requests to the source volume; and recording I/O operations to the source volume in the snapdifference file.
    • 描述了用于在存储网络中创建和使用快速差分文件的示例性存储网络架构,数据架构和方法。 一种示例性方法可以在存储网络中的处理器中实现。 该方法包括检测源卷中的故障以及响应于该故障:终止与向源卷生成I / O请求的一个或多个应用的​​通信; 刷新源音量; 将备份数据集复制到源卷,并在复制备份数据集时:激活新的快照文件; 重新启动与向源卷生成I / O请求的一个或多个应用程序的通信; 并将记录I / O操作记录到snapdifference文件中的源卷。

    • Exemplary storage network architectures, data architectures, and methods for data restore operation are disclosed. In one embodiment, a storage device comprises a processor, a memory module communicatively connected to the processor, and logic instructions in the memory module which, when executed by the processor, configure the processor to receive a signal that identifies a source volume and a first target snapshot that represents a point in time copy of the source volume, update metadata to define an restore relationship between the first target snapshot and the source volume, execute a background copy process between the first target snapshot and the source volume, and manage input/output operations during the background copy process to permit input/output operations to the source volume during the background copy process.
