Restoring MySQL Database

[RoaRk]

So, I have a script (not mine) which makes rolling backups of the MySQL database for my server. My question is how do I then restore back to the previous database setup in the event of a malicious attack. Here is the script I am using...

@echo off
COLOR 0B
echo ©©©                      DayZ Database Backup Script                        ©©©
echo ©©©                                                                          ©©©
echo ©©©          This Script will backup your database every 30 minutes          ©©©
echo ©©©                    To end this Script, just close it.                    ©©©
echo ©©©                                                                          ©©©
echo ©©©                                                                          ©©©
echo ©©©                                                                          ©©©
echo ©©©                                                                          ©©©
echo ©©©                                                                          ©©©
echo ©©©                                                                          ©©©
echo ©©©                                                                          ©©©
echo ©©©                                                                          ©©©

This works perfectly well as far as backing up that folder and deleting backups that are older than 2 hours, but as you can see it backs up the "\data\dayz" folder which contains .frm files. I feel like I have tried to restore the database by just replacing the files in "\data\dayz" with the files from a backup, but it didn't do anything. Do I have to delete or move "ib_logfile0" and "ibdata1" in "MySQL Server 5.5\data"? in order for this to work? Someone let me know what I'm missing here. Thanks!
