This class can be used to backup large MySQL databases into multiple files. It can list the tables of a given MySQL database and generate SQL statements to create and insert records with the current values of the table rows, as if it was creating a new database. The class stores the generated SQL statements in files. A full backup process can be split in multiple iterations to not exceed PHP default script execution time limit. Each iteration dumps a limited number of table rows. An iteration can be executed by a script that redirects the page request to itself at the end to proceed to the next iteration.
