Abstract

The invention provides a rapid data migration method and device. The method comprises the following steps: docking a target system through an SQLite database; obtaining a root page number of the target database and field structure information of a table; traversing the target database based on the root page number to collect all free pages and free blocks in the target database; determining the minimum effective data length in the target database according to the obtained field structure information, and quickly screening the obtained free pages and free blocks based on the minimum effective data length; and carrying out data migration on the screened free pages and free blocks. According to the method, the SQLite database is used as a database for bearing migration data, so that the earlier-stage preparation work of data migration and the management work in the data migration process are greatly reduced; and screening of the distributed data in the target database is realized by determining the minimum valid data length, so that the processing speed of invalid data is effectively improved, and the data migration efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of computer data migration, because it relates to a method and device for fast data migration. Background technique [0002] With the rapid development of communication technology and the professional expansion of social division of labor, interpersonal communication and social relations are showing a mainstream trend of systematization, networking and refinement. The demand for data capacity of servers is increasing, and data restoration and migration are becoming increasingly important. Current outstanding issues in this field. How to quickly implement data migration has become a research hotspot and difficulty. Specifically, during the data migration process, there are a large number of free pages and free blocks in the database, and valuable data may be stored in these free pages and free blocks, and the valuable data in these free pages and free blocks The extraction will take a lot of time. [0003] Therefore...
