Which is why it ends up being the DBA's fault. "Why didn't you predict the increase in storage requirements - for YOUR database - 2 years ago so we could budget for the disk???"
LOL - goooood one ;-)
important thing is that you collect i.e. have historicay raw disk usage or better said historical DB storage usage data ... thereafter, you can use different methods to 'forecast' future needs ... if you get good input from business, great! - usually you don't ... so, under this condition, in order to avoid severe reprimand (as Hans mentioned above) you can use simple linear regression, add 30% on top of it for 'financial crisis inquiry commission' and no one can tell you 'Why you didn't predict the storage requirements' ;-)
