Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] The present invention provides a real estate file efficient cloning method, which can meet the real estate industry's needs for the backup and migration of a large number of key files such as production data, equipment status information, and security monitoring records. Figure 1 The specific plan is as follows:

[0024] At the source end (A), an intelligent algorithm is used to quickly identify (B) key files in the real estate data management system, and files to be copied are selected according to actual needs. A parallel reading mechanism is adopted, and multi-threading and parallel processing technologies are used to read data (C) from multiple source locations. During the reading process, a lock mechanism is adopted to avoid conflicts and interference between multiple file reading tasks. A caching mechanism is used to reduce disk I / O operations. By pre-reading and caching frequently used data, during the reading process, a Copy-on-Write (COW) mechanism is adopted to read only the data that has changed, and the unchanged data is quickly copied by referencing the data blocks on the source storage medium to improve data reading efficiency. Multiple files are packaged into a data packet and the data is losslessly compressed (D). Using a high-speed network interface and breakpoint resumption technology, the compressed data is transmitted to the target end (E). During the transmission process, a hash value calculation verification mechanism and parallel processing technology are adopted to perform parallel verification (F) on the integrity and accuracy of multiple data packets. Once data errors or damages are found, the transmission is terminated and error information is fed back to the source end for timely warning. If the verification passes, the data file is transmitted to the target end (H). At the target end, system resources are reasonably allocated, and the data is written into the storage device according to the file structure and organization method of the source end (G). Thus, the file cloning is completed. The present invention provides an efficient real estate file cloning method and system, which improves the efficiency of file copying, ensures the integrity and accuracy of files, reduces the risk of data loss or damage, and better meets the needs of the real estate department to utilize data resources, improve operation efficiency and security, and reduce operation costs.
