1、备份确定的表
mysqldump -u username -p dbname table1 table2 ...> BackupName.sql
例子，备份coshaho001下customer，product表
备份结果

2、备份多个数据库
mysqldump -u username -p --databases dbname2 dbname2 > Backup.sql
例子，备份coshaho001，coshaho002库
3、 备份所有库
mysqldump -u username -p --all-databases > BackupName.sql
4、数据库恢复
mysql -u root -p < Backup.sql
例子
或者
mysql -uroot -p source Backup.sql;
