Database growth in the past

Hello,

Our requirement is to plan space increase of the drives based on last year's database growth. we have a third party monitoring tool that monitors the growth but today when I tried to pull the data, It gave me blank graphs as it got corrupted.

Is there a way in SQL server 2005 to tell me how my database grew/ by how much it grew in last year so that I can plan the hard disk space increase??

Thanks in advance

Sql doesn't keep those info that long.

Hmm!! I thought so..

thanks
