1 数据库常用备份方案

数据库备份方案：

全量备份
增量备份
差异备份

备份方案	特点
全量备份	全量备份就是指对某一个时间点上的所有数据或应用进行的一个完全拷贝。数据恢复快。备份时间长
增量备份	增量备份是指在一次全备份或上一次增量备份后，以后每次的备份只需备份与前一次相比增加和者被修改的文件。这就意味着，第一次增量备份的对象是进行全备后所产生的增加和修改的文件；第二次增量备份的对象是进行第一次增量备份后所产生的增加和修改的文件，如此类推。没有重复的备份数据备份时间短恢复数据时必须按一定的顺序进行
差异备份	备份上一次的完全备份后发生变化的所有文件。差异备份是指在一次全备份后到进行差异备份的这段时间内对那些增加或者修改文件的备份。在进行恢复时，我们只需对第一次全量备份和最后一次差异备份进行恢复。

2 mysql备份工具mysqldump

//语法：
    mysqldump [OPTIONS] database [tables ...]
    mysqldump [OPTIONS] --all-databases [OPTIONS]
    mysqldump [OPTIONS] --databases [OPTIONS] DB1 [DB2 DB3...]
    
//常用的OPTIONS：
    -uUSERNAME      //指定数据库用户名
    -hHOST          //指定服务器主机，请使用ip地址
    -pPASSWORD      //指定数据库用户的密码
    -P#             //指定数据库监听的端口，这里的#需用实际的端口号代替，如-P3307
 
// 备份整个数据库
[root@192 ~]# mysqldump -uroot -p123 --all-databases > all-$(date '+%Y%m%f%H%M%S').sql
mysqldump: [Warning] Using a password on the command line interface can be insecure.
[root@192 ~]# ls
all-202206%f183142.sql  anaconda-ks.cfg
// 备份school库的tb_course
[root@192 ~]# mysqldump -uroot -p123 school tb_course > tb_course.sql
mysqldump: [Warning] Using a password on the command line interface can be insecure.
[root@192 ~]# ls
all-202206%f183142.sql  anaconda-ks.cfg  tb_course.sql


// 备份school库
[root@192 ~]# mysqldump -uroot -p123 school > school.sql
mysqldump: [Warning] Using a password on the command line interface can be insecure.
[root@192 ~]# ls
all-202206%f183142.sql  anaconda-ks.cfg  school.sql  tb_course.sql
