ABSTRACT:
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.
