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.

the %F element of the format string combines the DBID,and sequence number to generate a unique filename. %F must be included in any control file autobackup format.
