一、单独备份 1、经典整库备份：backup as compressed backupset database include current controlfile plus archivelog delete all input; 2、tablespace：backup tablespace 名字; 3、数据文件：backup datafile n; (n:具体的数据文件编号select file_name,file_id,tablespace_name from dba_data_files;) 4、控制文件：backup current controlfile;或者backup database include current controlfile; 5、日志文件：backup archivelog all;或者 database plus archivelog; 6、参数文件：backup spfile; 7、全库备份脚本： 复制代码 代码如下: run{ allocate channel c1 type disk; backup full tag ‘dbfull' format ‘/backup/full%u_%s_%p' database include current controlfile; sql ‘alter system archive log current'; #在数据库进行全备份完成之后，需要执行该条命令将当前日志归档，备份归档日志时应该包括最后生成的归档 backup filesperset 3 format ‘/backup/arch%u_%s_%p'#filesperset 3设定每个备份集里文件不超过3个 archivelog all delete input; #备份归档可选，可以单独定期备份 release channel c1; } 二、增量备份 1、0级增量备份 复制代码 代码如下: run{ allocate channel c1 type disk; backup incremental level 0 tag ‘db0' format ‘/backup/db0%u_%s_%p'database include current controlfile; ; sql 'alter system archive log current';#在数据库进行全备份完成之后，需要执行该条命令将当前日志归档，备份归档日志时应该包括最后生成的归档 backup filesperset 3 format ‘/backup/arch%u_%s_%p'#filesperset 3设定每个备份集里文件不超过3个 archivelog all delete input; #备份归档可选，可以单独定期备份 release channel c1; } 2、1级备份脚本 复制代码 代码如下: run{ allocate channel c1 type disk; backup incremental level 1 tag ‘db1' format ‘/backup/db1%u_%s_%p' database skip readonly include current controlfile; backup filesperset 3 format ‘/backup/arch%u_%s_%p'#filesperset设定每个备份集里文件不超过3个 archivelog all delete input; #备份归档可选，可以单独定期备份 release channel c1; } （编辑：武汉站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
