PERIODIC DATA REPLICATION
First Claim
1. A method for data replication from a production server to a backup server, comprising:
- recording at least one operation performed on one or more data items stored in a volume of a production server, wherein the at least one operation is recorded as at least one journal event in a memory;
determining whether a system malfunction incident has occurred in the production server;
transferring the at least one journal event from the memory to an auxiliary storage unit at a first time instant, when it is determined that the system malfunction incident has occurred;
transferring, at a second time instant, one or more additional journal events recorded in the memory between the first and second time instants to the auxiliary storage unit; and
sending at least one journal event stored in the auxiliary storage unit for replication to a backup server.

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.
