A device for verifying consistency of data of a master device and a slave device, comprising:

• a first acquisition module, configured to acquire first data of the master device and first data of the slave device, respectively, each first data comprising a data file of a checkpoint and a log file;
• a second acquisition module, configured to recover data according to the received first data of the master device and the received first data of the slave device respectively to acquire second data of the master device and second data of the slave device, each second data being data recovered according to the data file of the checkpoint and the log file;
• a third acquisition module, configured to generate third data of the master device and third data of the slave device according to the second data of the master device and the second data of the slave device, each third data comprising the second data and at least one primary key and characteristic values of the second data;
• a comparison module, configured to compare the third data of the master device with the third data of the slave device;
• and
• an output module, configured to output verification results.
