When the system time of server 1 has arrived the BACKUP TIME of user's setting, derive module 101 and be used for needing backed up data to derive database 11, generate data file.Be spaced between the data in the data file that is generated, separate through symbol " | " that the data between row and the row are separated through newline like the data between hurdle and the hurdle.
For example; The user need carry out moon to the data of database 11 to be changeed; Be that each moon changes backup, then which of every month change the date, like totally 31 files from No. 1 to No. 31 with as wheel; In the present embodiment, when changeing, moon can be " prefix db+ wheel change date+said BACKUP TIME " to the naming method of file.If be No. 2 and be the wheel commentaries on classics date that then this second judge module 103 was judged the file that whether exists in the server 1 with No. 2 called afters " db02+ BACKUP TIME " same day.
If the user need carry out week wheel commentaries on classics to the data in the database 11; It is each week wheel commentaries on classics backup; Then what day of each week to change the date as wheel with, like totally 7 files from Monday to Sunday, Monday, the name of corresponding file folder can be " db Monday+BACKUP TIME ".
If do not exist with the same day in the server 1 is the file that wheel changes the date name; Then to be used to generate one be the file that wheel changes the date name with the same day to backup module 104, and the backup file of above-mentioned generation is stored in the file of this generation with the corresponding journal file of this backup file.
If existed with the same day in the server 1 is the file that wheel changes the date name, and then update module 105 is used for the backup file of above-mentioned generation is covered said file and identical file and the daily record of this backup file name with the corresponding journal file of this backup file.
As shown in Figure 3, be the operation process chart of data back up method preferred embodiment of the present invention.
