Abstract:
Systems and methods for replicating data from a production server to a backup server include recording at least one operation on one or more data items stored in a volume of a production server. The operation may be recorded as at least one journal event in a memory. A determination may then be made regarding whether a system malfunction incident has occurred in the production server and if so, a first set of journal events may be transferred from the memory to an auxiliary storage at a first time instant. At a second time instant, a second set of journal events recorded in the memory between the first and second time instants may be transferred to the auxiliary storage. At one journal event stored in the auxiliary storage unit may then be sent for replication to a backup server.
