Backing up and restoring MySQL database
MySQL database backup
To backup MySQL database one can use 'mysqldump' program. Syntax for mysqldump is:
mysqldump -u <mysql_username> -p <database_name> > <database_name>.sql
To automatically compress the database before it is stored on disk the output of mysqldump can be passed through bzip2 as:
mysqldump -u <mysql_username> -p <database_name> | bzip2 > <database_name>.sql.bz2
Restoring MySQL database
To restore MySQL database we can use 'mysql' command line client. Command to restore database is:
cat <dump_file>.sql | mysql -u <mysql_username> -p <database_name>
To restore a compressed database along with password we can take help of 'bunzip2' and 'sshpass' utilities in following manner:
bunzip2 -c <dump_file>.sql.bz2 | sshpass -p <mysql_database_password> mysql -u <mysql_username> -p <database_name>
