#1. Use Mysqldump Utility to Repair MySQL Database Without the Backup File

Mysqldump can make a copy of all your important stuff in that cabinet and put it in a safe place. It can also restore that copy if something bad happens to your original data. To use this versatile tool, you need to type some advanced commands into your computer. These words tell the tool what to copy and where to put it. You can also use it to fix your copied stuff when you need it.

Follow the syntax:

backup: # mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql

To repair your database enter this command:

restore: # mysql -u root -p[root_password] [database_name] < dumpfilename.sql

There’s another way to make a copy of your stuff, but it’s a bit more complicated. 

#2. Creating a Backup of a Single Table

You can choose which database file you want to copy. To do this, you need to use some commands again, but this time you tell the tool which file to copy. You can even put a lock on the copy to keep others from seeing it.

Follow the below command:

mysqldump -u [username] –p [password] -h [host] [databaseName] [tableName] > [backup-name].sql

#3. Using MySQL Client and OUTFILE Statement 

 To safely make a copy of a book, you need to either close the database or at least lock the book you want to copy.

You can use advanced commands to do this. First, you lock the part of the database you want to copy. 

LOCK TABLES tableName READ;

Follow the below command to accomplish a LOCK TABLES on the database:

mysql -u [username] –p [password] -h [host]

Then, you make a copy of that part and save it somewhere safe. 

After you’re done copying, you unlock the database so other people can use it again. 

USE databasename;
LOCK TABLES tablename READ;
FLUSH TABLES;

Follow the below command to backup the database table:

USE databasename;
LOCK TABLES Tablename READ;
FLUSH TABLES;
SELECT * INTO OUTFILE ‘databasetableBackup.sql’ FROM tablename;
UNLOCK TABLES;

Remember: This is a complicated process, and it’s important to be careful when doing this.
