　　邮件信息：

　　####注意备份文件夹是按照备份的时间命名的。
[root@localhost allback]# lltotal 12drwx------ 2 root root 4096 Apr  9 15:41 20130409154138drwx------ 2 root root 4096 Apr  9 15:42 20130409154252drwx------ 2 root root 4096 Apr  9 15:49 20130409154830[root@localhost allback]# ll 20130409154138  total 144-rw-r--r-- 1 root root 138338 Apr  9 15:41 backup-data-rw-r--r-- 1 root root    537 Apr  9 15:41 index-rw-r--r-- 1 root root    146 Apr  9 15:41 zrm_checksum## 注意：        每个备份的目录的下面有三个文件　　七 测试一个增量备份：
　　首先需要开启mysql的binlog日志 在my.cnf增加：log-bin=binlog  重启数据库
[root@localhost mysql-zrm]# mysql-zrm --action backup --backup-set zengliang_back  --backup-level 1####中间输出省略，只要并出现error基本成功，不保险的话就查看下备份文件即可[root@localhost mysql-zrm]# lltotal 16drwx------ 5 root root 4096 Apr  9 15:48 allbackdrwx------ 4 root root 4096 Apr  9 15:33 mysqldrwx------ 3 root root 4096 Apr  9 15:45 ytt_inc2drwx------ 3 root root 4096 Apr  9 16:11 zengliang_back[root@localhost mysql-zrm]# ll zengliang_back/total 4drwx------ 2 root root 4096 Apr  9 16:11 20130409161118[root@localhost mysql-zrm]# ll zengliang_back/20130409161118/total 12-rw-r--r-- 1 root root 445 Apr  9 16:11 backup-data-rw-r--r-- 1 root root 583 Apr  9 16:11 index-rw-r--r-- 1 root root 160 Apr  9 16:11 zrm_checksum　　八  这就完成了全局和增量备份的操作了，大家可以测试下恢复在原有的数据库mysql上做一个全局备份，然后新建一个表t_table，做一个增量备份。然后把mysql删除。最后先全局---增量做恢复
全局恢复：mysql-zrm --action restore --backup-set mysql --source-directory /var/lib/mysql-zrm/allback/20130409150029/增量恢复：mysql-zrm --action restore --backup-set zengliang_back  --source-directory /var/lib/mysql-zrm/zengliang_back/20130409161629/
