Hi Ware Adams, thanks for your answer. Here's another question:
Is it possible to set MySQL to save all the changes that can happen, for example, if some one insert a new record into table X, MySQL save a log about this task performed and all data that was inserted. I another person update one field from table Y, MySQL save all the information about this change. So, If something happens after the backup, we can recover the database without go back and perform again the insert and the update? If "yes", where can I find documentation about this? Thansk a lot.
