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<2、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<1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<注意：1级备份需要在0级备份的基础上执行。

3、支持全备和增量备份
