  • Data backup method and apparatus
    Patent number: 11256715
    Abstract: A method and an apparatus for data backup are disclosed. The method includes querying a slave for check information, where the check information is data inserted into a master when data written to the master is copied into the slave in a form of a log; obtaining a time at which the check information is inserted into the master and setting the time as a backup completion time point; and deleting data record(s) that is/are earlier than the backup completion time point from mirrored data, the mirrored data being data that is synchronously written to a defined storage space when the data is written to the master. The method for data backup is easy to implement at a low cost, and provides highly secure data backup.
