备份全库：

mydumper-uroot-p'xxxxxDB2015!@#'-o/mnt/backup/

备份mysqlhqdb数据库：

mydumper-uroot-p'xxxxxDB2015!@#'-Bmysqlhqdb-o/mnt/backup/

备份多张表(tableA,tableB)：

mydumper-uroot-p'xxxxxDB2015!@#'-Bmysqlhqdb-TtableA,tableB-o/mnt/backup/

备份tableA表的数据，不备份表结构

mydumper-uroot-p'xxxxxDB2015!@#'-Bmysqlhqdb-TtableA-m-o/mnt/backup/

备份tableA表的数据，并进行压缩

mydumper-uroot-p'xxxxxDB2015!@#'-Bmysqlhqdb-TtableA-c-o/mnt/backup/

还原mysqlhqdb库：

myloader-uroot-p'xxxxxDB2015!@#'-Bmysqlhqdb-d/mnt/backup/

还原tableA表

myloader-uroot-p'xxxxxDB2015!@#'-Bmysqlhqdb-otableA-d/mnt/backup/

mysqldump和mydumper的速度对比

首先用mydumper进行全库备份，耗时为12分钟

[root@iZ252affh68Zmnt]#timemydumper-uroot-p'xxxxxDB2015!@#'-o/mnt/backup/real12m19.526suser3m29.925ssys0m36.017s

再用mysqldump全库备份，耗时为18分钟

[root@iZ252affh68Zmnt]#timemysqldump-uroot-p'xxxxxDB2015!@#'--single-transaction--all-databases>/mnt/backup/all.sql--Warning:Skippingthedataoftablemysql.event.Specifythe--eventsoptionexplicitly.real18m0.563suser5m53.119ssys0m48.295s
