I am somewhat new to mysql. I created some databases recently and, to back them up, I just copied the folders with those database names in the mysql data directory (i.e containing only db.opt, .frm, and .ibd files). Unfortunately, my computer crashed. I now realize I did not back up the databases in the correct way (as I understand now, I should either have backed up the entire mysql data directory or used mysqldump). However, is there any way to recover the information from these data folders or is it lost?
