Hi,
I've reduced my disk usage from 673000 to 166516 Hopefully this
helps but I think the other big users have to do the same (ie.
Adrian, Michael, Wang, Tim, Tavi, etc.) I also think the inactive
users like Wang, Hauke, Tong ?, Tim ?, Mosser, etc. could be backed-
up and then moved to some other machine which isn't backed up
regularly but from which they could recover the files they need if
and when they are needed.
Cheers,
Douglas
