1)建立增量备份
RMAN>BACKUP INCREMENTAL LEVEL 0 FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
RMAN>BACKUP INCREMENTAL LEVEL 1 FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
RMAN>BACKUP INCREMENTAL LEVEL 2 FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
(2)建立累积备份
RMAN>BACKUP INCREMENTAL LEVEL 0 FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
RMAN>BACKUP INCREMENTAL LEVEL 2 FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
RMAN>BACKUP INCREMENTAL LEVEL 2 cumulative FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
RMAN>BACKUP INCREMENTAL LEVEL 1 FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
RMAN>BACKUP INCREMENTAL LEVEL 0 FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
RMAN>BACKUP INCREMENTAL LEVEL 1 FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
RMAN>BACKUP INCREMENTAL LEVEL 2 FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
(2)建立累积备份
RMAN>BACKUP INCREMENTAL LEVEL 0 FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
RMAN>BACKUP INCREMENTAL LEVEL 2 FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
RMAN>BACKUP INCREMENTAL LEVEL 2 cumulative FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
RMAN>BACKUP INCREMENTAL LEVEL 1 FORMAT='/u01/backup/rmanbk/%d_%s.dbf' tablespace users;
