使用Rman的Plus archvielog选项简化数据_sqlserver

oracle9i开始Rman提供plus archivelog选项，极大的简化了Rman备份的操作。

当你定义plus archivelog语句时，RMAN执行如下步骤的操作：
1。运行一个ALTER SYSTEM ARCHIVELOG CURRENT命令
2。运行BACKUP ARCHIVELOG ALL命令。注意如果备份优化被启用，RMAN只会备份未备份过的日志

3。备份BACKUP命令中定义的文件
4。运行ALTER SYSTEM ARCHIVELOG CURRENT命令
5。备份所有的剩下的归档日志

测试备份脚本：

backup database format ‘/opt/oracle/orabak/full_%d_%T_%s’plus archivelog format ‘/opt/oracle/orabak/arch_%d_%T_%s’delete all input;

测试日志:

通过plus archivelog,简化了备份操作，同时确保需要的日志都被备份。
