Select MYSQL and right mouse click and click . Once it has stopped, you will it’s status become blank instead of .

Similarly look for the location of the data folder. Once you located it,
I recommend you back up the folder or just rename it.

One thought on “Mysql data backup restore from corrupted system

  1. The MySQL server at both the machines MUST be stopped. Of course if the OS/hard disk crashed, the server at that machine is already stopped.
    Now, MySQL installation is in 2 folders (for me at least) ->
    1. Program Files / Program Files (x86), and
    2. C:\Program Data\MySQL in windows 7 and C:\Users\All users\Application Data\MySQL in Windows XP. Note that Program Data(win7) as well as Application Data(WinXP) are hidden folders.
    We are ONLY CONCERNED with the MySQL Server ** folder in the Application Data or Program Data folders. The Mysql folder in Program Files is of no use as it does not have your data.
    Now Copy the my.ini file in MySQL Server ** folder.
    Open the data folder and copy these files
    1. All the ib_logfile* files
    2. All the ibdata* files
    3. The database folders (that you want) containing .frm and .ibd files
    Now, copy the files mentioned in the above two points in the destination machine. It is highly recommended to take a backup of the replaced files in the destination machine.
    Now, restart the server. If you went right, you would restore your databases without any error.
