oracle rman实验(oracle rman differential差异备份和恢复)

首先清除原来的备份

rman > delete backupset;

 

接下来开始进行备份

rman > run{

rman > CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

rman > BACKUP OPTIMIZATION ON;

rman > CONTROLFILE AUTOBACKUP ON;

rman > CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'd:/rman_backup/%F';

rman > allocate channel d1 type disk format 'd:/rman_backup/%U;

rman > allocate channel d2 type disk format 'd:/rman_backup|%U;

rman > backup incremental level 0 database filesperset 3 plus archivelog filesperset 10

rman > delete all input;

rman > release channel d1;

rman > release channel d2;

rman >}

 

这样备份完成，好了接下来对相关的数据进行一些修改，修改后进行下一步，进行一个增量差异备份：

 

rman > run{

rman > CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

rman > BACKUP OPTIMIZATION ON;

rman > CONTROLFILE AUTOBACKUP ON;

rman > CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'd:/rman_backup/%F';

rman > allocate channel d1 type disk format 'd:/rman_backup/%U;

rman > allocate channel d2 type disk format 'd:/rman_backup|%U;

rman > backup incremental level 1 database filesperset 3 plus archivelog filesperset 10

rman > delete all input;

rman > release channel d1;

rman > release channel d2;

rman >}

 

备份完成了，shutdown数据库，然后delete掉所有的数据文件，控制文件和redo先保留

 

sqlplus / as sysdba

SQL > startup mount

 

C:/Documents and Settings/Administrator>rman nocatalog target /

已连接到目标数据库: LEARN (DBID=2605952657, 未打开)
使用目标数据库控制文件替代恢复目录

RMAN> restore database;

RMAN> recover database;

RMAN> alter database open;

 

总的来说相当的简单。实验完成
