摘要: Proposed are a storage system and a data recovery method capable of guaranteeing data recovery processing at a service level sought by a user. This storage system and data recovery method uses one or more data recovery candidate points and specifies a section containing the journal and the replication of write data, checks a redundancy relation of a write range in the volume of write data written from host into the volume contained in the journal regarding one or more the journals in the section, and executes redundancy elimination processing of merging a plurality of the replications of write data or a plurality of the journals into a single replication of write data or a single journal based on the check result.

摘要: The present invention maintains mapping information denoting which real areas have been allocated to which virtual areas for a virtual volume, the capacity of which is dynamically expanded. The present invention also maintains real area management information denoting which real areas have been allocated to which virtual areas. The real area management information is referenced to determine whether or not a low-reliability real area, which is a real area for which reliability has been lowered by the occurrence of a failure in a certain physical storage device, and which belongs to a RAID group comprising this certain physical storage device, has been allocated to a virtual area. A data restore process is not carried out for a low-reliability real area that has not been allocated to a virtual area, but a data restore process is carried out for a low-reliability real area that has been allocated to a virtual area.
