oracle rman 增量备份脚本

Posted 2020-07-06

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

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

数据备份目录

1. $ mkdir -p /u01/backup/rmanbk

首先将过期天数设为7天

1. 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

1. vim rman_bk_level0.sh
2. ------0级备份----------------
3. #! /bin/bash
4. export ORACLE_SID=orcl
5. export NLS_LANG=‘AMERICAN_AMERICA.ZHS16GBK‘
6. /u01/app/oracle/11.2.0/dbhome_1/bin/rman target / <<EOF
7. run{
8. allocate channel d1 type disk;
9. allocate channel d2 type disk;
10. backup incremental level 0 database format ‘/u01/backup/rmanbk/level0_%d_%s_%p_%u.bkp‘;
11. sql ‘alter system archive log current‘;
12. backup archivelog all delete input format ‘/u01/backup/rmanbk/log_%d_%s_%p_u%.bkp‘;
13. }
14. crosscheck backup;
15. delete noprompt obsolete;
16. exit;
17. <<EOF
18. ------------------

1级备份脚本

1. vim rman_bk_level1.sh
2. ---------1级增量备份---------------
3. #! /bin/bash
4. export ORACLE_SID=orcl
5. export NLS_LANG=‘AMERICAN_AMERICA.ZHS16GBK‘
6. /u01/app/oracle/11.2.0/dbhome_1/bin/rman target / <<EOF
7. run{
8. allocate channel d1 type disk;
9. allocate channel d2 type disk;
10. backup incremental level 1 database format ‘/u01/backup/rmanbk/level1_%d_%s_%p_%u.bkp‘;
11. sql ‘alter system archive log current‘;
12. backup archivelog all delete input format ‘/u01/backup/rmanbk/log_%d_%s_%p_u%.bkp‘;
13. }
14. crosscheck backup;
15. delete noprompt obsolete;
16. exit;
17. <<EOF

2级备份脚本

1. vim rman_bk_level2.sh
2. ---------2级增量备份---------------
3. #! /bin/bash
4. export ORACLE_SID=orcl
5. export NLS_LANG=‘AMERICAN_AMERICA.ZHS16GBK‘
6. /u01/app/oracle/11.2.0/dbhome_1/bin/rman target / <<EOF
7. run{
8. allocate channel d1 type disk;
9. allocate channel d2 type disk;
10. backup incremental level 2 database format ‘/u01/backup/rmanbk/level2_%d_%s_%p_%u.bkp‘;
11. sql ‘alter system archive log current‘;
12. backup archivelog all delete input format ‘/u01/backup/rmanbk/log_%d_%s_%p_u%.bkp‘;
13. }
14. crosscheck backup;
15. delete noprompt obsolete;
16. release d1;
17. exit;
18. <<EOF

加入到crontab中

1. crontab -e
2. -----------
3. #周日0级备份
4. 00 23 * * 0 /u01/backup_shell/rman_bk_level0.sh
5. #周一、二、四、五、六2级增量备份
6. 00 23 * * 1,2,4,5,6 /u01/backup_shell/rman_bk_level2.sh
7. #周三1级增量备份
8. 00 23 * * 3 /u01/backup_shell/rman_bk_level1.sh
