RMAN备份步骤

RMAN备份与恢复(WINDOW)

1、 建RMAN库作为恢复目录库

set echo on spool makedb1.log create database rman datafile 'd:oracleoradatarman_datasystem.dbf' size 50m autoextend on next 640K logfile ' d:oracleoradatarman_dataredo0101.log' SIZE 10M, ' d:oracleoradatarman_data/redo0201.log' SIZE 10M maxdatafiles 30 maxinstances 8 maxlogfiles 64 character set US7ASCII national character set US7ASCII;

可以采用DBCA进行建RMAN库

2、 建立RMAN表空间和RMAN用户

Conn / as sysdba --创建表空间RMAN CREATE TABLESPACE rman DATAFILE ‘E:oracleproduct10.2.0oradatarmanrman01.dbf’ SIZE 20m DEFAULT STORAGE(INITIAL 100k NEXT 100k PCTINCREASE 0); --创建用户RMAN CREATE USER rman IDENTIFIED BY rman TEMPORARY TABLESPACE TEMP DEFAULT TABLESPACE RMAN QUATO UNLIMITED ON RMAN ; --赋RECOVERY_CATALOG_OWNER、connect、resouce权限 GRANT RECOVERY_CATALOG_OWNER TO RMAN ; GRANT CONNECT,RESOURCE TO RMAN ;

3、 注册目标数据库

D:>RMAN CATALOG rman/rman@rman msglog=rman.log RMAN>CREATE CATALOG RMAN>EXIT D:>RMAN TARGET SYS/ADMIN@ORCL RMAN>CONNECT CATALOG RMAN/RMAN@RMAN RMAN>REGISTER DATABASE ; RMAN>EXIT ;

4、 开始备份

l 全备

D:> RMAN RCVCAT rman/rman@rman TARGET sys/admin@orcl cmdfile 'E:RmanBackupfullback.rcv'

fullback.rcv全备脚本：

run{ allocate channel c1 type disk; backup full tag 'Full' filesperset 5 format 'D:backup%d_Full_%T_%u_%p_%c' database include current controlfile; sql 'alter system archive log current'; backup archivelog all filesperset 5 format 'D:backup%d_Log_%T_%u_%p_%c'; sql 'alter system archive log current'; release channel c1;}
