采用0112111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

配置控制文件备份路径

RMAN > CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO ‘/u01/backup/rmanbk/ccontrolfile_%F‘;

数据备份目录

首先将过期天数设为7天

下面开始创建0级 1级 2级备份脚本

0级备份脚本

vim rman_bk_level0.sh
------0级备份----------------
#! /bin/bash
export ORACLE_SID=orcl
export NLS_LANG=‘AMERICAN_AMERICA.ZHS16GBK‘
/u01/app/oracle/11.2.0/dbhome_1/bin/rman target / <<EOF
run{
allocate channel d1 type disk;
allocate channel d2 type disk;
backup incremental level 0 database format ‘/u01/backup/rmanbk/level0_%d_%s_%p_%u.bkp‘;
sql ‘alter system archive log current‘;
backup archivelog all delete input format ‘/u01/backup/rmanbk/log_%d_%s_%p_u%.bkp‘;
}
crosscheck backup;
delete noprompt obsolete;
exit;
<<EOF
------------------

1级备份脚本

vim rman_bk_level1.sh
---------1级增量备份---------------
#! /bin/bash
export ORACLE_SID=orcl
export NLS_LANG=‘AMERICAN_AMERICA.ZHS16GBK‘
/u01/app/oracle/11.2.0/dbhome_1/bin/rman target / <<EOF
run{
allocate channel d1 type disk;
allocate channel d2 type disk;
backup incremental level 1 database format ‘/u01/backup/rmanbk/level1_%d_%s_%p_%u.bkp‘;
sql ‘alter system archive log current‘;
backup archivelog all delete input format ‘/u01/backup/rmanbk/log_%d_%s_%p_u%.bkp‘;
}
crosscheck backup;
delete noprompt obsolete;
exit;
<<EOF

2级备份脚本

vim rman_bk_level2.sh
---------2级增量备份---------------
#! /bin/bash
export ORACLE_SID=orcl
export NLS_LANG=‘AMERICAN_AMERICA.ZHS16GBK‘
/u01/app/oracle/11.2.0/dbhome_1/bin/rman target / <<EOF
run{
allocate channel d1 type disk;
allocate channel d2 type disk;
backup incremental level 2 database format ‘/u01/backup/rmanbk/level2_%d_%s_%p_%u.bkp‘;
sql ‘alter system archive log current‘;
backup archivelog all delete input format ‘/u01/backup/rmanbk/log_%d_%s_%p_u%.bkp‘;
}
crosscheck backup;
delete noprompt obsolete;
release d1;
exit;
<<EOF
