To ensure data security and business continuity, the company has built a primary and backup disaster recovery system. The construction information of the disaster recovery system is as follows:

(1) The production center and disaster recovery center use asynchronous remote control. (2) Business data synchronization time is about 8 hours per day. (3) The daily data increment is about 1500 MB. (4) The cycle is once every 4 hours. Based on the above background assessment, the company's IT technicians concluded that a disaster recovery network bandwidth greater than 0.5 Mbps would meet the requirements.
