This is all good, but it doesn't work too well for planning. Is there a rule of thumb I can use for a general overview? Say I want 125TB space and I want to dedup that for backup use. It'll probably be quite efficient dedup, so long alignment will match. By the way, is there a way to auto-align data for dedup in case of backup? Or does zfs do this by itself?
