On the morning of October 19, leaders from CSCLR and Gansu Provincial Department of Land and Resources signed an agreement for remote backup for electronic data, marking the official operations for remote backup. The backup data chiefly include digital data generated by "collection, management and utilization" of cores and samples, location plan of geological boreholes database nationwide, profile map of exploration line, drill column, data and chemical analysis data sheet and other geological data. This project ensures the security of electronic data (digitalized cores and samples), and further improves the disaster- tolerance and disaster-prevention capacity of informatization.
