Data Backup Mechanism and Optimization Based on Rsync in Central Meteorological Observatory

For any national Disaster Monitoring Forecasting in Central Meteorological Observatory (CMO) is based on the real-time data supporting.More than 500G data are updated daily.Great amounts of them need to be used continuously.So,Its back-up and timely recovery under any unusual circumstances is obviously very important for the security of The real-time services in CMO.Considering so many operating systems in CMO and the differences usage or authority to their files,the data backup solution based on Rsync has been proposed and improved gradually in practical.It can backup different data or operating systems by different way.This brings good result in practical.
