Sometimes MySQL database can become inaccessible because of internal database corruption errors, hardware failure, software failure, power interruptions etc. Each possible database failure error requires a different recovery action. Protect your data against the possibility of data loss by having a well known recovery strategy in place. 

The tips I’m about to give you, it won’t cost you thousands of dollars—in fact, implementing these tips won’t cost you a cent. And they can easily be used by any user. My Guide will help you to recover your MySQL database in few hours. When you will apply any recovery strategy on your database then first check:

  • The database can be in recoverable stage?
  • Mark the time that will be spent to recover your database?
  • Mark the time that spent to performing backup operations?

Before taking the backup first shutting down the database to ensure that no further transactions occur, and then simply backing it up. Storing it on a different medium in case of failure or damage to the original. You can then rebuild the database if it becomes damaged or corrupted in some way. Take backup on regular basis to avoid the data loss.
