建议备份策略
无论是累计还是差异，都进行如下两步
1、向前寻找一个增量备份基点
2、备份这个基点以来发生变化的数据块
差异增量：向前寻找基点的方法是<=本备份级别
累计增量：先前寻找基点的方法是<本备份级别
寻找到这个基点以后，自这个基点以来发生变化的所有的数据块都进行备份。
周日零点 0级备份
周一零点 2级备份
周二零点 2级备份
周三零点 1级备份
周四零点 2级备份
周五零点 2级备份
周六零点 2级备份
对于上面的备份策略备份的数据如下
增量备份
周日零点 0级备份 对数据库进行全备
周一零点 2级备份 备份呢周日到周一的数据
周二零点 2级备份 备份周一到周二的数据
周三零点 1级备份 备份周日到周三的数据
周四零点 2级备份 备份周三到周四的数据
周五零点 2级备份 备份周四到周五的数据
周六零点 2级备份 备份周五到周六的数据
累计备份
周日零点 0级备份 对数据库进行全备
周一零点 2级备份 备份呢周日到周一的数据
周二零点 2级备份 备份周日到周二的数据
周三零点 1级备份 备份周日到周三的数据
周四零点 2级备份 备份周三到周四的数据
周五零点 2级备份 备份周三到周五的数据
周六零点 2级备份 备份周三到周六的数据

第一条语句表示要生成级别为1的、tag值为'arch_copy'，针对整个数据库的，并且应用于增量备份的镜像副本。
1、第一天执行该程序，执行第一句话的时候，由于我们没有0级备份，因此会生成整个数据库的镜像副本（该副本不是普通的副本，而是可以在其上应用增量备份）
执行第二条语句的时候，，因为没有增量备份，因此不会执行，但是也不会报错。
2、第二天执行该程序，由于已经有了第一天的0级备份，所以会生成一个1级别的增量备份，执行第二条语句的时候，会将第一条语句生成的增量备份应用到第一天所生成的镜像副本上。以后的每一天都会生成一个增量备份，并将该生成的增量备份应用到镜像副本上，如果过需要恢复，先恢复镜像副本，然后应用最近一次增量备份以来，所生成的所有归档日志，即可进行数据库恢复。
