    RMAN BACKUP configured to asm

    953330
      Vinoth here.....Hi to all

      We have rman backup in our environment and rman backup location is in local server '/oracle/app/oracle/rman_backpup' like this, when i check with that physical location no backup file is found. It seems like backup is stored in asm diskgroup '+DGBACKUP'. I am confused because i saw the rman log file which is written to a file during the rman backup process, it shows the backup is available in '/oracle/app/oracle/rman_backpup'. can anyone explain hw it happens because i am new to asm environment.

      Thanks in advance

          Hi,

          you gave little to no information to really help you further.

          => How does your RMAN script to do backup look like?
          => What does "list backup" tell you?
          => How is your db_recovery_file_dest set to?
          => What version of DB are you using, Is this single instance or RAC etc.etc.?

          Regards
          Sebastian

            Not knowing what your script looks like, it is because you have more than likely configured db_recovery_file_dest=+DGBACKUP.

            you may need modify your script to point your disk backup to your back up file system. Reading the documentation should give you what you need.

                Hi Friends,

                Finally i got the RMAN Backup script file and i came to know that they are taking backup as they specified in the RMAN LOG location and then it is compressed to another location, so that the backup is not placed in the ASM disk. Thanks for ur support
