I have several mail systems, each having approx. 4 million files. On
     an average day approximately 10-20% of the files change, so I am
     looking at incrementals that will backup approx. 400,000 - 800,000
     files each day. The files are small, around 1k-2k on average, and my
     initial tests indicate that I can get approx 20,000 files per hour.
     The testing was done between a "HP-UX A.09.04 E 9000/847" and a IBM
     ES9000. The testing does not appear to be touching the network, nor is
     it taxing the mainframe or HP box. I would like to be able to backup
     each of system within a 6-8 hour window.

     Does any one have a similar situation, and if so how have you tuned
     the system to move this many files?

     Does any one have any firm numbers on the quatity of files that can be
     backed up in a 1 hour period?

     Any suggestions????????



     ****Please not that the numbers above are very rough and only a result
     of some prelimiary testing.


     Thanks in advance.
