      Dear All
      We are running Oracle 10g( on Solaris 10
      I want to gzip up my rman backups, which are to disk.
      How do I add the command to my script so after end of backup it starts gzipping it.
      Please find the script below

      export ORACLE_BASE=/app/oradataerp/oraprod
      export ORACLE_HOME=/app/oradataerp/oraprod/db/tech_st/10.2.0
      export ORACLE_SID=PROD
      export LD_LIBRARY_PATH=${ORACLE_HOME}/lib
      export PATH=${ORACLE_HOME}/bin:${ORACLE_HOME}/lib:${PATH}
      export DATE=`/usr/bin/date +%Y%m%d`
      rman target sys/***** nocatalog msglog /nfs-bkp-erp/PROD-ERP/PROD-DB/RMAN.${DATE}.log <<EOF
      crosscheck archivelog all;
      #backup database format '/nfs-bkp-erp/PROD-ERP/PROD-DB/PROD_t%t_s%s_p%p%c';
      #backup current controlfile format '/nfs-bkp-erp/PROD-ERP/PROD-DB/PROD_cntrl_t%t_s%s_p%p%c';
      #delete noprompt archivelog All complEted before 'SYSDATE-10';
      crosscheck backup;
      #delete expired archivelog all;
      delete obsolete;
      crosscheck backup;

          make another script
          see how long it takes for ur RMAN backup.
          And then schedule ur script through crontab accordingly

            you can use compress backupset command in which compression is done by rman.

              You can add this line to your scripit..

              ls -ltr filename*|awk '{print $9}'|xargs gzip----->to GZIP the new backup files

                Why complicate easy things ? As already stated, the compression can be "on the fly".

                  When using compression, you will need to actually test to see which backup compression gives you the best compression/performance. Higher compression = slower performance, Lower compression ratio = more performance.

                  To make your life a lot easier when trying to do backups, make sure you do rman backup to disk, then sweep these backups to tape. The restore would then be much faster.
