I'm not sure that I correctly understand the reserve parameter. I have
heard that it is used to get amanda to degrade full dumps to merely
incremental dumps if the holding disk gets full. I assume the percentage
refers to how full. So how does degrading to incrementals help if the
holding disk is 100% full? What am I misunderstanding here? I can
understand saying that if the holding disk is 75% full, switch to
incrementals though.
