RMAN 增量备份shell脚本

前2天给公司的测试库写了个shell备份脚本，复杂的不会写，只能先从简单的入手，现贴出脚本文件供大家学习参考，有不对的地方也请大家多多指出！

把每天的脚本代码写进一个sh文件然后设置crontab

crontab如下

10 1 * * 0 /u01/crontab_bp_shell/sunday_bp.sh

10 1 * * 1 /u01/crontab_bp_shell/monday_bp.sh

10 1 * * 2 /u01/crontab_bp_shell/tuesday_bp.sh

10 1 * * 3 /u01/crontab_bp_shell/wendesday_bp.sh

10 1 * * 4 /u01/crontab_bp_shell/thursday_bp.sh

10 1 * * 5 /u01/crontab_bp_shell/friday_bp.sh

10 1 * * 6 /u01/crontab_bp_shell/saturday_bp.sh

好了，一个简单的备份策略就这样出来了！
