The invention discloses a method for recovering a whole MySQL
database. The method is characterized by comprising the following steps that S100, a MySQL
database file is carved, wherein a magnetic disk is scanned, file features are searched for, a table
data file and a table structure file with the file features are obtained, the files are reconstructed according to the serial number of a
data page and a table space identifier, and a table definition file is saved; S200, the
database file is correlated, wherein the carved MySQL
database file and the engine type of the MySQL database are matched, and the table structure file is correlated with the corresponding table
data file; S300, a table structure is recovered, wherein whether the table
data file is correlated with the corresponding table structure file or not is judged, if yes, S400 is executed, and otherwise, the table structure is recovered according to the engine type; S400, the
database file is recovered.
