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
- $ mkdir -p /u01/backup/rmanbk
首先将过期天数设为7天
- RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
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
