MySQL provide a great command line utility to take backup of your MySQL database and restore it. mysqldump command line utility is available with MySQL installation (bin directory) that can be used to achieve this.

1. Getting backup of a MySQL database using mysqldump.

Use following command line for taking backup of your MySQL database using mysqldump utility.

Code language: SQL (Structured Query Language) (sql)
mysqldump –-user root –-password=myrootpassword db_test > db_test.sql or mysqldump –uroot –pmyrootpassword db_test > db_test.sql
Code language: SQL (Structured Query Language) (sql)

2. Backup multiple databases in MySQL.

                        }catch(Exception e) {

    please give me an example.

  4. Joe says:

    to back up all databases use –all-databases, not -all-databases. At least in my browser that’s how the code appears from this page (as an en-dash maybe?).

  5. Joe says:

    I think this blog forces two hyphens to become an en-dash.

    to back up all databases use – – all-databases (two hyphens), not -all-databases (one hyphen). At least in my browser that’s how the code appears from this page.

  6. NIraj Patel says:

    Hi Viral,
    Thnks for your article.
    I want to share something.

    We can also take Dump only rows selected by the given WHERE condition.

    shell> mysqldump –user [username] –password=[password] [database name] [table name] where = “[condition]”\ > /tmp/sugarcrm_accounts_contacts.sql

    shell> mysqldump –user root –password=myrootpassword db_test customers where = ” id=’15’ ” \ > db_test_customers.sql

    • @Niraj: Thanks for sharing that snippet. Definitely useful to many of us.
      Good work. Much appreciated :)

    i took mysql database backup in windows server and i restored that mysql db in linux pc.. its sucessfully restored ..i connected that mysql db in client xp mechine ..i compiled that db procedure but its show tables doesn’t exit..will u pls tel how to solve this problem

  10. Ilan Hazan says:

    Restoring a dump table into the MySQL master server can lead to serious replication delay.
    To overcome the replication delay, caused by restoring the dump table on the master, there is a need to widespread the massive inserts. This can be done by the MySQL SLEEP command.
    See As restoring a dump table into the MySQL master – you better get some sleep

  11. Jennifer says:

    What does the -h command do? I have been trying to figure it out and I don’t know what it does in the command line. See, like on this tutorial they do it:

    But on others they don’t… Anyone know?

  12. khan says:

    i tried mysqldump to backup it worked ie file .sql is created but when i try to restore it it also shows sucess but tables are not created

  13. raj says:

    mysqldump is a comment.. don run it in mysql…..

    mysqldump -u root -p password db_test > db_test.sql

  14. Alejandro Arauz says:

    The only problem with the mysqldump command is that you need privileges to execute this command on the server. I had this problem before in a shared enviroment and I found this tool: MySQLBackupFTP ( It has a free version that allows you to connect to MySQL through phpMyAdmin so you don’t need admin access to the server. I hope this help others with the same problem.

  25. gude says:

    hi i m able to take the backup and even zip the data
    now after i unzip the code i m not able to restore the same file.
    can u provide me some suggestions.

  26. i just want to say please check your “syntaxes”. FOR Backup multiple databases the right syntax is . mysqldump –user root –password=myrootpassword –databases db_test db_second db_third > db_test.sql

    please don’t mind and i request you to provide right sysntaxes. Please go through once again..

  27. Matt says:

    Thanks for the tips. I was stuck on the correct syntax. This helped a lot.

  28. Ahmed Khan says:

    I think in second example you need to add “–databases” before the database names. so new command should look like:

    mysqldump –-user root –-password=myrootpassword --databases db_test db_second db_third > db_test.sql

  29. luoly says:

    I think you missed a space before the password, and the commands “–database” before [database name] can’t be omitted:

    mysqldump –uroot –pmyrootpassword db_test > db_test.sql

    should be:

    mysqldump –uroot –p myrootpassword -database db_test > db_test.sql

    mysqldump is too trouble to learn, you can try the software – Automatic Backup Scheduler for MySQL ( ) to back up and resotre your databases.

    a really quick noob question. The command ‘mysqldump’ makes the backup and deletes the original database or does it leave it untouched? Thank you in advance.

    I want to take object-wise db backup. Like all tables, all views, all functions.
    I tried this with reference to one of the comments posted above:

    mysqldump -u [username] -p [password] [database_name] –all-tables

    but this didn’t work and mysql ignored “–all-tables”.
    Appreciate your help !!!

    Often I meet MySQL database when working on WordPress projects. As for me I use dbForge Studio for MySQL for all tasks of MySQL management and administration. Speaking about backup I want to say that its built in MySQL backup tool ( ) is very fast and easy to use! Few steps and you’ll get a dump file of any size!

    Ran the string, no errors but nothing else either. Just goes to the next line from original prompt MySql> to simply –>. What the heck does that mean? Dont see dump file anywhere on the system either. Just starting to use MySql so maybe it is meaningful but… Anybody some ideas?

  40. Magesh M says:

    @ GIlbert,

    You can mention the path whihc you want to create the backup, if you not mentioned the backup location by default it was stored at “/root” directory.

    See the below comamnd for path.

    mysqldump -u root -p [password] [database-name] | gzip -9 > database-name.sql.gz

    Hi team,
    Could anyone help me how we can reduce the time for mysqldump and restoring data into new database. I am doing this process on AWS RDS instance database

    Database Volume: 45 gb, duration is 4 hours
    dump size: 2.5 gb (zip)

    Restore database: 45 gb, duration is 10 hours.

    Is there any better option to do this process as quick as possible?


  50. Kuldip says:

    I am trying to dump using mysqldump command but I am getting following error.

    Info: Using unique option prefix ‘pass’ is error-prone and can break in the future. Please use the full name ‘password’ instead.

    I tried all the combination, but still not working. I used -p, -pass, –password.

    I am using MariaDB.

  51. Prince says:

    Thanks for instruction you have given.
    but my following commands gives error as
    “D:\xampp\mysql\bin>mysqldump -um1 -pm2 test > db_test1.sql
    mysqldump: Got error: 1044: Access denied for user ”@’localhost’ to database ‘?
    um1’ when selecting the database”

    mysqldump –um1 –pm2 test > db_test1.sql
    mysqldump –-user m1 –-password=m2 test > db_test2.sql

    here m1 = user name
    m2 = password
    host = localhost.
    And yes this works fine once i will do the PDO connection.
