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<<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; } EOF

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<<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 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; } EOF

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
