POS terminal key data backup recovery method

Abstract

The invention provides a POS terminal key data backup recovery method. The POS terminal key data backup recovery method comprises the following steps: copying the out-factory preset menu data guided into the POS terminal and the necessary data for the system of Data region to the data backup region; sending the specific service to the POS terminal through the remote updating mode or the beforehand preset mode, using the specific service for copying the key data of the current POS terminal to the data backup region; while starting the POS terminal for hanging and loading the Data file system each time, the hanging and loading operation of the file system fails, formatting the Data region, setting the data recovery zone bit, starting the system and recovering the data; if the hanging and loading operation of the file is successful, there is no need to recovery the data. The POS terminal key data backup recovery method has the advantages as follows: expanding the data backup region; effectively processing the impact to the data recovery process for abnormal power down, the backup can be automatically achieved for the key data, the data can be automatically checked and automatically recovered.

Description

technical field [0001] The invention relates to a data backup and recovery method, in particular to a POS terminal key data backup and recovery method. Background technique [0002] For the current multimedia self-service POS terminals with battery-free design, these multimedia self-service POS terminals are usually placed in shopping malls or self-service places, and most of the shopping malls or self-service places adopt the method of directly powering off, so repeated abnormal power failures will cause serious damage to The stability of the product file system is affected to a certain extent, resulting in the loss of file system data. For the problem of data loss caused by repeated abnormal power failures, the current common solution is that the user manually backs up the current data, and then manually restores the data in the case of data loss, which may cause forgetting to back up the data or not Key data is backed up, which leads to problems such as unusable products...
