1、数据库全备到硬盘
[oracle@centos7 scripts]$ cat rman_backup.sh
source /home/oracle/.bash_profile
rman target / log=/home/oracle/backup/backupall_rman.log<<EOF
run
{
allocate channel ch2 device type disk; #分配通道
allocate channel ch3 device type disk;
sql 'alter system archive log current'; #归档当前日志
backup database format '/home/oracle/backup/db_%d_%T_%U'; #备份数据文件
sql 'alter system archive log current';
backup archivelog all format '/home/oracle/backup/arch_%t_%s' delete all input; #备份归档文件
backup format '/home/oracle/backup/con_%s_%p' current controlfile; #备份控制文件
crosscheck backup;
crosscheck archivelog all;
delete noprompt expired backup;
delete noprompt obsolete;
delete noprompt backup of database completed before 'sysdate -15'; #删除15天之前的数据库备份集
delete noprompt archivelog all;
delete noprompt backup of archivelog all completed before 'sysdate -15'; #删除15天之前的归档备份集
release channel ch2;
release channel ch3;
}
EOF2、增量备份脚本
0级增量
[oracle@centos7 scripts]$ cat rman_backup_level0.sh
source /home/oracle/.bash_profile
rman target / log=/home/oracle/backup/backupall_rman.log<<EOF
run
{
allocate channel ch2 device type disk; #分配通道
allocate channel ch3 device type disk;
sql 'alter system archive log current'; #归档当前日志
backup incremental level 0 database format '/home/oracle/backup/db_level0_%d_%T_%U'; #备份数据文件
sql 'alter system archive log current';
backup archivelog all format '/home/oracle/backup/arch_level0_%t_%s' delete all input; #备份归档文件
backup format '/home/oracle/backup/con_level0_%s_%p' current controlfile; #备份控制文件
crosscheck backup;
crosscheck archivelog all;
delete noprompt expired backup;
delete noprompt obsolete;
delete noprompt backup of database completed before 'sysdate -15'; #删除15天之前的数据库备份集
delete noprompt archivelog all;
delete noprompt backup of archivelog all completed before 'sysdate -15'; #删除15天之前的归档备份集
release channel ch2;
release channel ch3;
}
EOF1级增量
[oracle@centos7 scripts]$ cat rman_backup_level1.sh
source /home/oracle/.bash_profile
rman target / log=/home/oracle/backup/backupall_rman.log<<EOF
run
{
allocate channel ch2 device type disk; #分配通道
allocate channel ch3 device type disk;
sql 'alter system archive log current'; #归档当前日志
backup incremental level 1 database format '/home/oracle/backup/db_level1_%d_%T_%U'; #备份数据文件
sql 'alter system archive log current';
backup archivelog all format '/home/oracle/backup/arch_level1_%t_%s' delete all input; #备份归档文件
backup format '/home/oracle/backup/con_level1_%s_%p' current controlfile; #备份控制文件

delete noprompt archivelog all;
delete noprompt backup of archivelog all completed before 'sysdate -15'; #删除15天之前的归档备份集
release channel ch2;
release channel ch3;
}
EOF注意：1级备份需要在0级备份的基础上执行。
