i2COOPY provides users with byte-level data replication service in real time. lt relies on data serialization transmission technology to strictly guarantee the consistency and integrity of data on the production side and the target side. Since it runs at the operating system, this software can capture new data at the byte level, featuring high real-time performance, small size of transmitted data, and low resource consumption on the production server. It operates regardless of storage hardware brands or physical/virtual machine environments, enabling efficient data replication between heterogeneous environments. The software can be used for data transmission between bank data centers, data replication between headquarters and business departments of securities companies, and other purposes.
