In order to meet the needs of a meteorological observatory to backup a great number of Micaps data files and set up local data application environment,this paper explores the program of using Delphi function to call WinRAR to compress,backup and restore Micaps data files on daily business.Designed on tray architecture,the Program uses thread class calling WinRAR to compress and backup daily Micaps data files which are divided into 10 different categories.The backup operation can be implemented in two ways,including automatic timing operation and manual operation,to pack and backup each category of daily Micaps data files respectively.The storage space occupied by the compressed backup files is less than 20% that of the original documents.The Program,characterized by stable operation,easy maintenance and function expansion,has good application prospects.
