Might be worth adding a media retention policy, I imagine you do the same for video which is far more expensive to store the raw, so add it for photography.
We don't have a written in stone policy, this kind of thing has to be flexible with the type of work, length and size of project. Generally for most clients it's gone within 30-90 days of final payment (which is when they get the deliverables). Broadcast TV stuff (not commercials) is usually kept a bit longer due to the nature of it.
Photoshoots are done in raw as well, and can easily be a few hundred gigs from one shoot.
