Rman Level012备份实验http://blog.csdn.net/u011364306/article/details/50036429
采用0221222增量备份策略,7天一个轮回
也就是周日0级备份，周1 2 4 5 6 采用2级增量备份，周3采用1级增量备份
打开控制文件自动备份
[sql]view plaincopy
- CONFIGURE CONTROLFILE AUTOBACKUP ON;?
11g控制文件自动备份新特性：http://blog.csdn.net/u011364306/article/details/50051303
配置控制文件备份路径
[sql]view plaincopy
- RMAN > CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO‘/file/backup/rman/controlfile_%F‘;?
将过期天数设为7天
[sql]view plaincopy
- RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;?
数据备份目录
[sql]view plaincopy
- $ mkdir -p /file/backup/rman/?
脚本解释：
[sql]view plaincopy
- vim rman_bak_level0.sh????
- #! /bin/bash??
- export ORACLE_BASE=/u01/oracle?
- export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1?
- export PATH=$ORACLE_HOME/bin:$PATH?
- export ORACLE_SID=neal??? --数据库ORACLE_SID
- export NLS_LANG=‘AMERICAN_AMERICA.ZHS16GBK‘--字符集
- rman target / <
- run{???
- allocate channel d1 type disk;?? --分配通道d1，类型备份到磁盘
- allocate channel d2 type disk;?? --分配通道d2，类型备份到磁盘
- backup incremental level 0 database format ‘/file/backup/rman/level0_%d_%s_%p_%u.bkp‘;?? --备份级别、输出格式、路径
- sql ‘alter system archive log current‘;??? --对当前redo日志进行归档
- backup archivelog alldelete input format ‘/file/backup/rman/archivelog_%d_%s_%p_%u.bkp‘;? --备份归档日志并删除
- crosscheck backup;?? --检查备份
- delete noprompt obsolete;? --静默删除过期备份
- release channel d1;? --释放通道d1
- release channel d2;? --释放通道d2
- }???
- EOF??
下面开始创建0级 1级 2级备份脚本
0级备份脚本
[sql]view plaincopy
- vim rman_bak_level0.sh?
- #! /bin/bash?
- export ORACLE_BASE=/u01/oracle?
- export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1?
- export PATH=$ORACLE_HOME/bin:$PATH?
- export ORACLE_SID=neal?
- export NLS_LANG=‘AMERICAN_AMERICA.ZHS16GBK‘
- rman target / <
- run{?
- allocate channel d1 type disk;?
- allocate channel d2 type disk;?
- backup incremental level 0 database format ‘/file/backup/rman/level0_%d_%s_%p_%u.bkp‘;?
- sql ‘alter system archive log current‘;?
- backup archivelog alldelete input format ‘/file/backup/rman/archivelog_%d_%s_%p_%u.bkp‘;?
- crosscheck backup;?
- delete noprompt obsolete;?
- release channel d1;?
- release channel d2;?
- }?
- EOF?
1级备份脚本
[sql]view plaincopy
- vim rman_bak_level1.sh?
- #! /bin/bash?
- export ORACLE_BASE=/u01/oracle?
- export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1?
- export PATH=$ORACLE_HOME/bin:$PATH?
- export ORACLE_SID=neal?
- export NLS_LANG=‘AMERICAN_AMERICA.ZHS16GBK‘
- rman target / <
- run{?
- allocate channel d1 type disk;?
- allocate channel d2 type disk;?
- backup incremental level 1 database format ‘/file/backup/rman/level1_%d_%s_%p_%u.bkp‘;?
- sql ‘alter system archive log current‘;?
- backup archivelog alldelete input format ‘/file/backup/rman/archivelog_%d_%s_%p_%u.bkp‘;?
- crosscheck backup;?
- delete noprompt obsolete;?
- release channel d1;?
- release channel d2;?
- }?
- EOF?
2级备份脚本
[sql]view plaincopy
- vim rman_bak_level2.sh?
- #! /bin/bash?
- export ORACLE_SID=neal?
- export NLS_LANG=‘AMERICAN_AMERICA.ZHS16GBK‘
- /u01/oracle/product/11.2.0/db_1/bin/rman target / <
- run{?
- allocate channel d1 type disk;?
- allocate channel d2 type disk;?
- backup incremental level 2 database format ‘/file/backup/rman/level2_%d_%s_%p_%u.bkp‘;?
- sql ‘alter system archive log current‘;?
- backup archivelog alldelete input format ‘/file/backup/rman/archivelog_%d_%s_%p_%u.bkp‘;?
- crosscheck backup;?
- delete noprompt obsolete;?
- release channel d1;?
- release channel d2;?
- }?
- EOF?
加入到crontab中
[sql]view plaincopy
- crontab -e?
- #周日0级备份?
- 00 23 * * 0 /server/scripts/rman_bak_level0.sh?
- #周一、二、四、五、六2级增量备份?
- 00 23 * * 1,2,4,5,6 /server/scripts/rman_bak_level2.sh?
- #周三1级增量备份?
- 00 23 * * 3 /server/scripts/rman_bak_level1.sh?
Rman备份中变量的含义
backup incremental level 0 database format=‘LEV0_%d_%t_%U_%s＿%p‘
format=string 文件路径和名称的格式串，其中可包含宏变量：
%c copy ID
%p backup piece ID
%s backup set ID
%e log sequence
%h log thread ID
%d database name
%n database name(x填充到8个字符)
%I DBID
%f file ID
%F DBID,day,month,year,and sequencer的复合
%N tablespace name
%t timestamp
%M mh mm格式
%Y year yyyy格式
%u backup set+time((x填充到8个字符)
%U %u_%p_%c
%% %
The format specifier %U is replaced with unique filenames for the files when you take backups.
