Abstract: Data is replicated on a backup node, where the granularity of the replication can be less than a full volume. A data consistency group comprising a subset of data for a volume is defined for a primary node. A set of differences for the data consistency group is sent to a backup node. The backup node creates change logs in response to receiving the set of differences. In response to receiving a request to access a file having data in the data consistency group, the backup node creates a clone of the file. The backup node determines whether an update to a data block of the file exists in the change logs. In response to determining that the update to the data block exists in the change logs, the backup node updates a copy of the data block for the cloned file with data in the change logs.
Abstract translation: 数据在备份节点上复制，其中复制的粒度可以小于完整卷。 为主节点定义包括卷的数据子集的数据一致性组。 数据一致性组的一组差异被发送到备份节点。 备份节点创建更改日志以响应接收到一组差异。 响应于接收到访问具有数据一致性组中的数据的文件的请求，备份节点创建该文件的克隆。 备份节点确定在更改日志中是否存在对该文件的数据块的更新。 响应于确定更改日志中存在对数据块的更新，备份节点使用更改日志中的数据更新克隆文件的数据块的副本。

Abstract: A system and method for efficiently restoring one or more data containers is provided. A common persistent consistency point image (PCPI) is identified between a source and a destination storage systems prior to the destination storage system performing a rollback operation to the commonly identified PCPI. Differential data is then transmitted from the source storage system in a line efficient manner to the destination storage system.

Abstract: A hardware and/or software facility to enable emulated storage devices to share data stored on physical storage resources of a storage system. The facility may be implemented on a virtual tape library (VTL) system configured to back up data sets that have a high level of redundancy on multiple virtual tapes. The facility organizes all or a portion of the physical storage resources according to a common store data layout. By enabling emulated storage devices to share data stored on physical storage resources, the facility enables deduplication across the emulated storage devices irrespective of the emulated storage device to which the data is or was originally written, thereby eliminating duplicate data on the physical storage resources and improving the storage consumption of the emulated storage devices on the physical storage resources.
