How to backup/restore data in mysql database very quickly?
mysqldump command line is the quickest to backup ,
(use mysql command line to restore , mysql -u #username# -p #database# < #dump_file#)
look on this examples
Following will backup and restore db at same time.
mysqldump -h #host -u #username -p #password --routines #source_dbname | mysql -h #host -u #user -p #password #destination_dbname

I have a single .sql file which is 800MB in size and contains a few of databases including tables and datas.
The problem is, how to restore this kind of dump since there is no CREATE DATABASE syntax in the file?
I try mysql> -u root -p --all-database < c:\data.sql but no joy.
Conducted a backup of the following.
mysqldump -u xxx -p --all-database > c:\data.sql
Or, in the database unit
mysqldump -u xxx -p --databases db_name > c:\data.sql
Recovery in the following code.
mysql -u root -p < c:\data.sql
I know how mysqldump works.
But dont know where to use it?
If I execute this command after starting mysql program then it says error.
I am using ubuntu. So how can I use this utility?
Backup your database this way too..
mysql -u root -p DB_NAME > db_name_backup.sql
If you want to backup all database simply run this
mysql -u root -p > mysql_db_backup.sql

mysqldump and mysql
MySQL Database Backup using mysqldump
shell> mysqldump --opt db_name > backup-file.sql
You can read the dump file back into the server like this:
shell> mysql db_name < backup-file.sql
Or like this:
shell> mysql -e "source /path-to-backup/backup-file.sql" db_name
mysqldump is also very useful for populating databases by copying data
from one MySQL server to another:
shell> mysqldump --opt db_name | mysql --host=remote_host -C db_name
It is possible to dump several databases with one command:
shell> mysqldump --databases db_name1 [db_name2 ...] > my_databases.sql
If you want to dump all databases, use the --all-databases option:
shell> mysqldump --all-databases > all_databases.sql
If tables are stored in the InnoDB storage engine, mysqldump provides a
way of making an online backup of these (see command below). This
backup just needs to acquire a global read lock on all tables (using
FLUSH TABLES WITH READ LOCK) at the beginning of the dump. As soon as
this lock has been acquired, the binary log coordinates are read and
lock is released. So if and only if one long updating statement is
running when the FLUSH... is issued, the MySQL server may get stalled
until that long statement finishes, and then the dump becomes
lock-free. So if the MySQL server receives only short (in the sense of
"short execution time") updating statements, even if there are plenty
of them, the initial lock period should not be noticeable.
shell> mysqldump --all-databases --single-transaction > all_databases.sql
For point-in-time recovery (also known as “roll-forward”, when you need
to restore an old backup and replay the changes which happened since
that backup), it is often useful to rotate the binary log (see
Section 8.4, “The Binary Log”) or at least know the binary log
coordinates to which the dump corresponds:
shell> mysqldump --all-databases --master-data=2 > all_databases.sql
or
shell> mysqldump --all-databases --flush-logs --master-data=2 > all_databases.sql
The simultaneous use of --master-data and --single-transaction works as
of MySQL 4.1.8. It provides a convenient way to make an online backup
suitable for point-in-time recovery if tables are stored in the InnoDB
storage engine.
For more information on making backups, see Section 6.1, “Database
Backups”.
mysqldump -u MYSQL_USER -h MYSQL_SERVER -pMYSQL_PASS --all-databases > "dbs.sql"
You use it directly on the terminal, just like mysql it self, and pass the parameters directly to it.
mysqldump -u [user] -p[password] [database name] > dumpfilename.sql
yes you can.
see http://dev.mysql.com/doc/refman/5.0/en/mysqldump.html for more information on the tool.
If it's an entire DB, then:
$ mysqldump -u [uname] -p[pass] db_name > db_backup.sql
If it's all DBs, then:
$ mysqldump -u [uname] -p[pass] --all-databases > all_db_backup.sql
If it's specific tables within a DB, then:
$ mysqldump -u [uname] -p[pass] db_name table1 table2 >
table_backup.sql
You can even go as far as auto-compressing the output using gzip (if your DB is very big):
$ mysqldump -u [uname] -p[pass] db_name | gzip > db_backup.sql.gz
If you want to do this remotely and you have the access to the server in question, then the following would work (presuming the MySQL server is on port 3306):
$ mysqldump -P 3306 -h [ip_address] -u [uname] -p[pass] db_name >
db_backup.sql
To IMPORT:
ype the following command to import sql data file:
$ mysql -u username -p -h localhost DATA-BASE-NAME < data.sql
In this example, import 'data.sql' file into 'blog' database using vivek as username:
$ mysql -u sat -p -h localhost blog < data.sql
If you have a dedicated database server, replace localhost hostname with with actual server name or IP address as follows:
$ mysql -u username -p -h 202.54.1.10 databasename < data.sql
OR use hostname such as mysql.cyberciti.biz
$ mysql -u username -p -h mysql.cyberciti.biz database-name < data.sql
If you do not know the database name or database name is included in sql dump you can try out something as follows:
$ mysql -u username -p -h 202.54.1.10 < data.sql
REfer: http://dev.mysql.com/doc/refman/5.6/en/mysqldump.html
I'm under VPN and I don't have SSH access to remote server.
I can connect to remote database by console
mysql -u username -p -h remote.site.com
Now I'm trying to clone the remote database to local computer
mysqldump -u username -p -h remote.site.com mysqldump | mysql -u root -ppassword webstuff
And I've got error
mysqldump: Got error: 1045: Access denied for user 'webstaff'#'10.75.1.2'
(using password: YES) when trying to connect
How to copy mysql database from remote server to local computer?
Assuming the following command works successfully:
mysql -u username -p -h remote.site.com
The syntax for mysqldump is identical, and outputs the database dump to stdout. Redirect the output to a local file on the computer:
mysqldump -u username -p -h remote.site.com DBNAME > backup.sql
Replace DBNAME with the name of the database you'd like to download to your computer.
Check syntax and execute one command at a time, then verify output.
mysqldump -u remoteusername -p remotepassword -h your.site.com databasename > dump.sql
mysql -u localusername -p localpassword databasename < dump.sql
Once you've matched all passwords, you can use pipe.
Often our databases are really big and the take time to take dump directly from remote machine to other machine as our friends other have suggested above.
In such cases what you can do is to take the dump on remote machine using MYSQLDUMP Command
MYSQLDUMP -uuser -p --all-databases > file_name.sql
and than transfer that file from remote server to your machine using Linux SCP Command
scp user#remote_ip:~/mysql_dump_file_name.sql ./
This can have different reasons like:
You are using an incorrect password
The MySQL server got an error when trying to resolve the IP address of the client host to a name
No privileges are granted to the user
You can try one of the following steps:
To reset the password for the remote user by:
SET PASSWORD FOR some_user#ip_addr_of_remote_client=PASSWORD('some_password');
To grant access to the user by:
GRANT SELECT, INSERT, UPDATE, DELETE, LOCK TABLES ON YourDB.* TO user#Host IDENTIFIED by 'password';
Hope this helps you, if not then you will have to go through the documentation

Copy mysql database from remote server to local computer
I ran into the same problem. And I could not get it done with the other answers. So here is how I finally did it (yes, a beginner tutorial):
Step 1: Create a new database in your local phpmyadmin.
Step 2: Dump the database on the remote server into a sql file (here I used Putty/SSH):
mysqldump --host="mysql5.domain.com" --user="db231231" --password="DBPASSWORD" databasename > dbdump.sql
Step 3: Download the dbdump.sql file via FTP client (should be located in the root folder)
Step 4: Move the sql file to the folder of your localhost installation, where mysql.exe is located. I am using uniform-server, this would be at C:\uniserver\core\mysql\bin\, with XAMPP it would be C:\xampp\mysql\bin
Step 5: Execute the mysql.exe as follows:
mysql.exe -u root -pYOURPASSWORD YOURLOCALDBNAME < dbdump.sql
Step 6: Wait... depending on the file size. You can check the progress in phpmyadmin, seeing newly created tables.
Step 7: Done. Go to your local phpmyadmin to check if the database has been filled with the entire data.
Hope that helps. Good luck!
Note 1: When starting the uniformer-server you can specify a password for mysql. This is the one you have to use above for YOURPASSWORD.
Note 2: If the login does not work and you run into password problems, check your password if it contains special characters like !. If so, then you probably need to escape them \!.
Note 3: In case not all mysql data can be found in the local db after the import, it could be that there is a problem with the mysql directives of your dbdump.sql
Better yet use a oneliner:
Dump remoteDB to localDB:
mysqldump -uroot -pMypsw -h remoteHost remoteDB | mysql -u root -pMypsw localDB
Dump localDB to remoteDB:
mysqldump -uroot -pmyPsw localDB | mysql -uroot -pMypsw -h remoteHost remoteDB
C:\Users\>mysqldump -u root -p -h ip address --databases database_name -r sql_file.sql
Enter password: your_password
This answer is not remote server but local server. The logic should be the same. To copy and backup my local machine MAMP database to my local desktop machine folder, go to console then
mysqldump -h YourHostName -u YourUserNameHere -p YourDataBaseNameHere > DestinationPath/xxxwhatever.sql
In my case YourHostName was localhost. DestinationPath is the path to the download; you can drag and drop your desired destination folder and it will paste the path in.
Then password may be asked:
Enter password: xxxxxxxx
Is there SQL command where you can do MySQL dump inside the MySQL console?
I tried mysqldump but it does not work...
I'm trying to output into SQL file.
You cannot run mysqldump within a MySQL console since mysqldump is an external command like the mysql console.
Exit the console and use the mysqldump command as follows:
mysqldump -u username -p -h hostname (or ip address) databasename > sqlfilename
It will ask for password.
More details of mysqldump can be found at http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html
use \!:
\! mysqldump -u username -p database > database_dump.sql
MySQL Documentation Reference (see System command)
use:
mysqldump -u username -p database
database: name of database
username: dbuser
I have dumped my database with the following command:
mysqldump -uuser -ppassword db_name > file
then I completely removed my database:
drop database db_name;
then I created a new database:
create database db_name;
and then I tried to restore the db with the following command:
mysqldump -uuser -ppassword db_name < file
The problem is that dump does not create tables and loads data in them and so the database remains empty however it does show a message like dump completed "date time"
What could be the reason for this?
mysqldump is for dumping the database. You've created a new empty database, and then dumped that empty database. Use mysql instead to reload your dump
mysqldump db > dump.sql
mysql drop/create
mysql db < dump.sql
would be the basic command sequence.
I like to do the following to restore.
mysql -uuser -ppassword
create database db;
use db;
source dump.sql;
I tried dump of my database with the following commands:
#mysqldump -u <username> -p <password> DB_name > <filename>.sql
Then login into the DB:
#mysql -u <username> -p <password>
>show databases;
>drop database <DB_name>;
Then create a new database:
#create database <DB_name>;
DB_name is userdefined name we can have any name.
and then restore the DB with the following command:
#mysql -u <username> -p <password> DB_name < <filename>.sql
