Backup And Restore MySQL Databases Using mysqldump

mysqldump lets you quickly and efficiently take a backup of a single database, multiple databases or even all of the databases on your server. This requires shell access to the server you wish to perform the commands on and the mysql login credentials for your user(s).


SSH access is not allowed on our shared or business shared services.  For more information on how to SSH into your server, please review:  Connecting To Your Server Via SSH


Backing Up A Single Database

To back-up a single database, log in via SSH and run the following commands.



mysqldump -u user -p[user_pass] [database_name] > dumpfile.sql



mysqldump -u root -pABC123 exampledb > exampledbdump.sql


The filepath for your database (.sql) backup will be your current working directory. You may use an absolute path as well, such as /root/exampledbdump.sql


Backing Up Multiple Databases

If you wish to backup two or more databases, you’ll need to specify –databases followed by the names of the databases you want to backup. Remember that the database user must have privileges to access the database that is being backed up.



mysqldump -u user -p[user_pass] --databases [database_name] [database_name] [database_name] > dumpfile.sql



mysqldump -u root -pABC123 --databases exampledb sampledb testdb > exampledb_sampledblsql_testdb.sql


Backing Up All Databases

Run the following command to back-up all current databases



mysqldump -u user -p[user_pass] --all-databases > all-dbs.sql



mysqldump -u root -pABC123 --all-databases > all-dbs.sql


Restoring Database(s)

Restore databases running the following command



mysql -u user -p[user_pass] [database_name] < dumpfile.sql



mysql -u root -pABC123 exampledb < exampledbdump.sql
