linux系统rman的自动备份脚本

3 rman自动备份脚本

完全备份脚本

rman target / <<EOF

run{

allocate channel 'dev1' type disk;

backup full tag 'dbfull_orcl' format '/u01/app/oracle/backup/fulldb_orcl%u_%p_%c'database;

sql 'alter system archive log current';

backup filesperset 3 archivelog all delete input;

release channel dev1;

}

增量备份：

0级备份脚本：

#set porfile_env

export ORACLE_SID=ora10g

# rman level0 backup

rman log='/u01/app/oracle/rmandir/log/db1_rman.log' append <<EOF

connect target /;

run

{

allocate channel c1 type disk;

backup incremental level=0 database format'/u01/app/oracle/backup/db1_level0_%U' tag='level0';

sql 'alter system archive log current';

backup archivelog all format'/u01/app/oracle/log/db1_arch_%U' delete input;

release channel c1;

}

EOF

1级备份脚本

# set porfile_env

export ORACLE_SID=ora10g

# rman level0 backup

rman log='/u01/app/oracle/rmandir/log/db1_rman.log' append <<EOF

connect target /;

run

{

allocate channel c1 type disk;

backup incremental level=1 database format '/u01/app/oracle/backup/db1_level1_%U' tag='level1';

sql 'alter system archive log current';

backup archivelog all format '/u01/app/oracle/log/db1_arch_%U' delete input;

release channel c1;

}

EOF

 

2级备份脚本：

# set porfile_env

export ORACLE_SID=ora10g

# rman level0 backup

rman log='/u01/app/oracle/rmandir/log/db1_rman.log' append <<EOF

connect target /;

run

{

allocate channel c1 type disk;

backup incremental level=2 database format '/u01/app/oracle/backup/db1_level2_%U' tag='level2';

sql 'alter system archive log current';

backup archivelog all format '/u01/app/oracle/log/db1_arch_%U' delete input;

release channel c1;

}

EOF

检查脚本：

export ORACLE_SID=ora10g

rman log='/u01/app//oracle/log/rmancheck.log' append <<EOF

connect target /;

run

{

# check database

backup validate check logical database;

 

# check backup set

restore database validate check logical;

}

EOF

删除过期备份文件脚本：

export ORACLE_SID=ora10g

rman log='/u01/app/oracle/log/rmandelset.log' append <<EOF

connect target /;

run

{

delete noprompt obsolete;

}

EOF

 

 

 

 

4 设置系统自动备份参数：

man增量备份计划，把用到的脚本贴出来，方便以后查找！

crontab 自动计划。设置自动执行计划,在rman初始化环境里面，打开自动备份控制文件功能

#crontab -e

0 1 * * 0 su – oracle -c /xxx/rmanlevel0.sh

//每周日1：00执行0级备份
0 1 * * 1-3,5-6 su – oracle -c /xxx/rmanlevel2.sh

//每周一至周三，周五至周六1:00执行2级增量备份
0 1 * * 4 su – oracle -c /xxx/rmanlevel1.sh

//每周四1：00执行1级增量备份
0 18 * * 6 su - oracle -c /xxx/rmancheck.sh

//每周六16点执行检测
0 18 * * 0 su – oracle –c /xxx/rman_delete.sh

//每周日18:00删除过期的的备份数据
