PROBLEM TO BE SOLVED: To provide a replication system capable of surely executing replication even in the case where update logs are rapidly stagnated by fault occurrence or the like, while implementing high-speed transfer of update logs, a job processing system, a replication method and a program.SOLUTION: A replication system comprises: a job processing system 100; and a backup system 200. The job processing system 100 includes: a storage device 30a for storing update object data and its update log; a storage device 40b of which the read speed and the write speed are lower than the storage device 30a but the storage capacity is higher; an update log transmission section 7 for transmitting the update log on the storage device 30a to the backup system 200; and an update log retreat section 5 for creating an update log file 11 including a plurality of update logs on the storage device 30a under a preset condition, temporarily storing the update log file 11 in the storage device 40a and then transmitting the update log file 11 to the backup system 200. |
