    • Techniques for virtualizing data are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for virtualizing data comprising identifying source data to be virtualized, intercepting an input/output (i/o) request to the source data, determining whether the input/output request is a read request or a write request, in the event the input/output request is a write request, storing one or more changes contained in the write request, and in the event the input/output request is a read request, determining whether a portion of data requested has been modified and responding to the read request. Responding to the read request may comprise providing stored data in the event a portion of the data requested has been modified, and utilizing source data in the event the data requested is unmodified.
    • 公开了虚拟化数据的技术。 在一个特定示例性实施例中,技术可以被实现为用于虚拟化数据的方法,包括识别要虚拟的源数据,截取对源数据的输入/输出(i / o)请求,确定输入/输出请求是否为 读请求或写请求,在输入/输出请求是写请求的情况下,存储写入请求中包含的一个或多个改变,以及在输入/输出请求是读请求的情况下,确定是否部分 所请求的数据已被修改并响应于读请求。 响应于读取请求可以包括在所请求的数据的一部分已经被修改的情况下提供存储的数据,并且在所请求的数据未被修改的情况下利用源数据。

    • Techniques for granular recovery of data from local and remote storage are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for recovery of data from local and remote storage comprising determining a recovery location, determining a location of backup data, hard linking one or more portions of the backup data to the recovery location in the event that the one or more portions of the backup data to be hard linked are determined to be on a volume of the recovery location, virtually linking one or more portions of the backup data to the recovery location in the event that the one or more portions of the backup data to be virtually linked are determined to be on a volume different from the volume of the recovery location, and performing recovery utilizing one or more portions of recovery data.
    • 公开了用于从本地和远程存储器精细地恢复数据的技术。 在一个特定示例性实施例中,这些技术可以被实现为用于从本地和远程存储器恢复数据的方法,包括确定恢复位置,确定备份数据的位置,将备份数据的一个或多个部分硬链接到恢复位置 在要硬链接的备份数据的一个或多个部分被确定为恢复位置的卷的情况下,在备份数据的一个或多个部分与备份数据的一个或多个部分实际上链接到恢复位置的情况下, 要虚拟链接的备份数据的更多部分被确定为与恢复位置的卷不同的卷,并且利用恢复数据的一个或多个部分来执行恢复。
