摘要： One code (a compressed redundant code) is created based on a plurality of first redundant codes, each created on the basis of a plurality of data units, and this compressed redundant code is written to a nonvolatile storage area. This compressed redundant code is used to restore either a data element constituting a multiple-failure data, or a first redundant code corresponding to the multiple-failure data, which is stored in an unreadable sub-storage area of a partially failed storage device, and to restore the data element constituting the multiple-failure data which is stored in a sub-storage area of a completely failed storage device, based on the restored either data element or first redundant code, and either another data element constituting the multiple-failure data or the first redundant code corresponding to the multiple-failure data.

摘要： An externally-connected volume of a main storage is correlated to an AOU volume inside of an external storage. The AOU volume is allocated with a not-yet-used page in a pool in accordance with data writing. When a command is issued to the externally-connected volume for formatting or others, a first controller in the main storage converts the command into a format command or an area deallocation command with respect to the AOU volume in the external storage. As such, the external AOU volume is subjected to a write process in its entirety, thereby being able to prevent any unnecessary page allocation. With such a configuration, the storage system of the present invention can use pages in the pool with good efficiency.
摘要翻译：主存储器的外部连接的卷与外部存储器内部的AOU卷相关。 AOU卷根据数据写入在池中分配尚未使用的页面。当向外部连接的卷发布命令以进行格式化时，主存储器中的第一控制器将该命令转换成相对于外部存储器中的AOU卷的格式命令或区域解除分配命令。因此，外部AOU卷整体地进行写入处理，从而能够防止任何不必要的页面分配。通过这样的结构，本发明的存储系统能够以良好的效率使用池中的页面。

摘要： Provided are a backup system and a backup method for backing up data written by a host into a logical volume provided by a storage system, wherein an update location in the logical volume updated by the host is managed, and the storage system is controlled to selectively back up the data written into the update location in the logical volume based on the management result of the update location. It is thereby possible to ensure a fast data read speed in the backup of raw volumes and an easy multiplatform backup, whereby a backup system and a backup method capable of performing backup efficiently are realized.
