mysqldump is an effective tool to backup MySQL database. It creates a *.sql file with DROP table, CREATE table and INSERT into sql-statements of the source database. To restore the database, execute the *.sql file on destination database. For MyISAM, use mysqlhotcopy method that we explained earlier, as it is faster for MyISAM tables.
Using mysqldump, you can backup a local database and restore it on a remote database at the same time, using a single command. In this article, let us review several practical examples on how to use mysqldump to backup and restore.
For the impatient, here is the quick snippet of how backup and restore MySQL database using mysqldump:

- The DBeaver window contains a menu bar, a toolbar, a shortcut bar, a workspace with one or more editors and views, and a status bar: By default, the menu bar contains the following menus: File menu contains menu items for the creation of files, folders, projects.

DBeaver (snap) won't let me export/import databases. dbeaver hot 51 Oracle: Can't download drivers after update to 7.0.1 hot 51 Reference to database and/or server name in 'KIOSK.sys.schemas' is not supported in this version of SQL Server hot 50. If you lose your data in MariaDB, but have been using mysqldump to make regular backups of your data in MariaDB, you can use the dump files to restore your data. This is the point of the back-ups, after all. To restore a dump file, it's just a matter of having the mysql client execute all.
How To Backup MySQL database
1. Backup a single database:
This example takes a backup of sugarcrm database and dumps the output to sugarcrm.sql
The sugarcrm.sql will contain drop table, create table and insert command for all the tables in the sugarcrm database. Following is a partial output of sugarcrm.sql, showing the dump information of accounts_contacts table:
2. Backup multiple databases:
Dbeaver Mysqldump Not Found
If you want to backup multiple databases, first identify the databases that you want to backup using the show databases as shown below:
For example, if you want to take backup of both sugarcrm and bugs database, execute the mysqldump as shown below:
Verify the bugs_sugarcrm.sql dumpfile contains both the database backup.
3. Backup all the databases:
The following example takes a backup of all the database of the MySQL instance.
Dbeaver Mysqldump Unknown Variable 'column-statistics=0'
4. Backup a specific table:
In this example, we backup only the accounts_contacts table from sugarcrm database.

4. Different mysqldump group options:
- –opt is a group option, which is same as –add-drop-table, –add-locks, –create-options, –quick, –extended-insert, –lock-tables, –set-charset, and –disable-keys. opt is enabled by default, disable with –skip-opt.
- –compact is a group option, which gives less verbose output (useful for debugging). Disables structure comments and header/footer constructs. Enables options –skip-add-drop-table –no-set-names –skip-disable-keys –skip-add-locks

How To Restore MySQL database
Mysqldump Everything
1. Restore a database
In this example, to restore the sugarcrm database, execute mysql with < as shown below. When you are restoring the dumpfilename.sql on a remote database, make sure to create the sugarcrm database before you can perform the restore.
2. Backup a local database and restore to remote server using single command:
This is a sleek option, if you want to keep a read-only database on the remote-server, which is a copy of the master database on local-server. The example below will backup the sugarcrm database on the local-server and restore it as sugarcrm1 database on the remote-server. Please note that you should first create the sugarcrm1 database on the remote-server before executing the following command.
