    The jobs are going to an external USB2 drive. I replaced this and watching the backup progress tonight it hasn't made any difference. Nothing in the Windows or Raid logs. No processes are peaking. No changes have been made to the machine that I can think to affect the backup like this.

    Would anyone have any ideas as to where the problem might lie? Looking at tonight's file count it seems to be slow, 6000 in 4 hours.
