Backuping slowly !

  Hi all,

   I've been using Oracle 11GR1 64 bit on Linux 64 OS. 

   I backup db into tape and lost about two hours to finish backuping. My db is 176GB

   After that, I restored from Tape to duplicate my db to test server. This work is OK. I can use new db to serve testing.

   This test server is only PC machine and I tried backup db to hard disk (local hard disk). But near eight hours, backuping not complete !

   My script that I used like:

=======================================================

   run

  {

crosscheck archivelog all;

delete noprompt expired archivelog all;

configure device type disk parallelism 2;

allocate channel rman_bk_ch01 type disk;
