It's about a year old but we ran out of space: > df -h Filesystem Size Used Avail Capacity Mounted on /dev/da0e 1.5T 1.4T 36G 98% /usr/data This time around I convinced them to make the project budget bigger. After I finish building this new primary system (dual xeon dual cores). I'll start building the other (much cheaper / slower) systems to offload most of that data to and then after that work on the even cheaper systems to backup those arrays. Tiered storage etc. etc. I'd estimate that we use around 1TB per year, it's a moving target that seems to be growing exponentially! -- BSD Podcasts @: http://bsdtalk.blogspot.com/ http://freebsdforall.blogspot.com/
