    • A method and system for recovering from a system failure wherein the failed system is restored to a new system that has different hardware. Hardware state is preserved during a backup process, and following a failure, a restore is performed to the extent possible using that hardware state but on a system having a different hardware configuration. Rules are provided for handling the differences through selective merging, arranging, and replacement of data, with the logic and work performed transparently to the user. Hardware state includes hard disk configuration information, the location (partition) of the operating system, devices installed on the system and any additional drivers to load. When restored, for hardware that is identical, the hardware state is restored as specified in the file. If the hardware state is not identical, then a set of rules are used to restore the hardware state. Via these rules, hard disks may be restored to differently sized or a different number of hard disks, disk mirror pairs may be handled appropriately, and so on. Critical devices that are required to restore the system are merged as necessary during the restore process, while new or different non-critical devices are preserved during the restore process for future use. Updated drivers may be used.
    • 一种从系统故障中恢复的方法和系统,其中故障系统恢复到具有不同硬件的新系统。 硬件状态在备份过程中被保留,并且在故障之后,使用该硬件状态尽可能地执行恢复,但在具有不同硬件配置的系统上执行恢复。 提供了通过选择性合并,排列和替换数据来处理差异的规则,逻辑和工作对用户透明地执行。 硬件状态包括硬盘配置信息,操作系统的位置(分区),系统上安装的设备以及要加载的任何其他驱动程序。 恢复时,对于相同的硬件,硬件状态将按文件中指定的方式恢复。 如果硬件状态不相同,则使用一组规则来恢复硬件状态。 通过这些规则,可以将硬盘恢复到不同大小或不同数量的硬盘,可以适当地处理磁盘镜像对,等等。 恢复系统所需的关键设备在还原过程中必要时进行合并,而在还原过程中保留新的或不同的非关键设备以供将来使用。 可能会使用更新的驱动程序。
