DATA BACKUP SYSTEM AND METHOD FOR SYNCHRONIZING A REPLICATION OF PERMANENT DATA AND TEMPORARY DATA IN THE EVENT OF AN OPERATIONAL ERROR

摘要

A data backup system and a method for sychronizing a replication of permanent data between primary and secondary disk subsystems and a replication of temporary data between primary and secondary computer servers in the event of an operational error are provided. The method includes detecting an operational error. The method further includes stopping replication of permanent data from the primary disk subsystem to the secondary disk subsystem at a first predetermined time, in response to the detection of the operational error. The method further includes stopping any further replication of temporary data from the primary computer server to the secondary computer server at the first predetermined time, in response to the detection of the operational error.
