限制rman消耗太多空间

郑全

-以最小负载方式运行RMAN备份

RMAN> run{
      backup as backupset duration 00:10 minimize load database  current controlfile;
      backup  duration 00:10 minimize load archivelog all  delete all input;
      }

--限定通道大小方式运行RMAN备份
RMAN> run{
allocate channel c1 device type disk rate 2m format '/home/oracle/db_%U.bak';
backup as backupset database include current controlfile plus archivelog all  delete all input;
release channel c1;
}
