            allocate channel c3 type disk;

            BACKUP AS COMPRESSED BACKUPSET DATABASE FORMAT='H:\backup\full_%d_%u_%s_%T';

                My db size is around 950GB

                We are not using recovery catalog.

                O.S is windows server 2008(64 bit) on which we are running oracle 11.2.0 32 bit enterprise edition And we are running this script manually in RMAN prompt.

                H Drive is external hard disk mapped with our server.

                  What I can see here:


                  running 32-bit Oracle on 64-bit OS. This begs the question: why?

                  850 Gb database: how many datafiles?

                  Backing up to a network drive (so this will be slow), and 3 channels all going to that network drive:

                  which means you must have an I/O bottleneck.

                  Also you provide minimal to 0 information to help you out, as you have your logfile going to the proverbial black hole.

                  You didn't post your backup script, as you don't show the RMAN command line. You can simply keep the log by using documented log= qualifier on the RMAN command line.

                  Also you didn't post the result of

                  show all


                  Why you are surprised it is slow and do you expect any valid help, with that little cooperation on your side?
