Abstract
A system and method for protecting data in a protected storage system. A replication of the protected storage system at a predetermined time point is stored in an object-based storage in replicated content objects of a target disk. Information related to a write operation in the protected storage system is obtained, the information including: data stored on the protected storage system and metadata related to the stored data. A journal is maintained by: including a copy of the stored data in a content entry in one or more journal content objects, including at least some of the metadata in a metadata entry in one or more metadata objects, storing the journal content objects and metadata objects in the object-based storage, and associating the metadata entry with the content entry. The data received before a predetermined time window is periodically moved from the journal to the target disk.
