Backup all files in /var/lib/mysql to another folder

To restore, stop mysqld if it is running

Move all database files back to /var/lib/mysql. Make sure that all the folder and files in that folder belongs to mysql

Try starting mysql

This command can be used to backup MySQL database.

mysqldump -u <User> -p <Database name> [<Table name>] > backup.sql

This command will create a file ‘backup.sql’ that will have all the data of the Database. The <Table name> is optional.

The database can be restored from such a dump using the command

mysql -u <User> <Database name> < backup.sql

Example

I backup all the task in Nexty using this command.

mysqldump -u root Apps_Nexty > nexty.sql

This will create a file called ‘nexty.sql’ - which can be restored using the command…

mysql -u root Apps_nexty < nexty.sql
