    If you look back at the question, you'll see that he's asking about a
    performance difference in the backup of the same (networked) machine in
    two different modes of Retrospect so it's unlikely "the network" is the
    cause.

    It's also possible that scheduled backups run at lower priority than
    immediatel backups - with the assumption that scheduled backups will
    run in the background, and possibly while the machine is in use,
    whereas immediate backups will typically be run in the foreground.

    At least that would be my guess. I only do immediate backups on my
    system.

    Nope. Same network, same amount of traffic, same Macs, same set of files.
     

    Same set in both cases.
     

    Of course. Hardware comp in the 4mm DAT.
     

    That's what I'm looking for info on. Has anybody else noticed the speed
    difference?

    Interesting possibility. I do run other apps on the Mac that runs Retro.
    A mail server and an RSS server, for example. It's also the firewall for
    my small LAN (using the absolutely excellent IPNetRouter).

    When Retro is doing anything with the tape drive, no other app gets any
    attention at all -- the mail server won't respond, and the RSS server
    won't serve. However, all the firewall functions -- NAT, data routing,
    and so on, don't seem to be affected at all. As I understand it, all of
    that happens down in the bowels of OT, so I suppose it has a very high
    priority.
