[Rman]Oracle Rman增量备份Level012脚本

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, day, month, year, and sequence number to generate a unique filename. %F must be included in any control file autobackup format.
