Abstract

The invention provides a data recovery and migration method and device. The method includes: a configuration step, configuring data recovery and migration tasks, and setting parameters associated with the tasks; a data reading step, according to the parameters, sequentially reading historical data in batches, and reading for each batch The historical data of the data file is separately generated and buffered, and the data range and read data mark of each data file are stored in Redis; and the data writing step is to obtain each batch of data to be restored from Redis according to the parameters Range and read data mark, if the read data is marked as failure, then terminate, otherwise, according to the data range, the buffered historical data will be restored to the source database or migrated to the target database in batches, and the data of each data file Range and write data tags are stored in Redis.

Description

technical field [0001] The invention relates to the field of computer technology and software, in particular to a method and device for data restoration and migration. Background technique [0002] With the increase of visits, the amount of online data is growing faster and faster. Operators need to periodically transfer the closed business data to the historical library or cloud storage. The transferred data is called historical data. However, historical data is not permanently sealed. It can be said that its subsequent survival is of greater significance, such as data analysis and restoration to the performance test environment for stress testing. In addition, for big data analysis or offline testing, it is necessary to migrate closed business data to the big data platform or test database. Therefore, there is a need for a method and device for restoring or migrating historical data. [0003] At present, there are several ways to restore data to the source database or mi...
