1. A computer-implemented method of protecting data in a protected storage system, the method comprising:
storing, in an object-based storage, a replication of the protected storage system from a predetermined time point, in fixed-size replicated content objects of a target disk, wherein a replicated content object stores data of an address apace of the protected storage system, wherein a replicated content object can be re-written but cannot be modified; obtaining data stored on the protected storage system following changes in the protected storage system, and metadata related to the stored data; maintaining a journal by:
including a copy of the stored data in a content entry in one or more journal content objects and storing the journal content objects in the object-based storage;including at least some of the metadata in a metadata entry in one or more metadata objects and storing the metadata objects in the object-based storage; andassociating the metadata entry with the content entry; and periodically applying the data received before a predetermined time window from the journal content objects to at least one replicated content object by obtaining, modifying and re-writing the at least one replicated content object. |
