Ask HN: What does your home media storage solution look like?

I am married with a two year old and one on the way. I have a DSLR camera + HDV Sony Camera. My jpegs are easily 1MB from the DSLR and each tape run off of the HDV is about 15 - 30GB. Capturing every moment has been important to us, but I am quickly running out of space - at an unsustainable rate. My setup is thus: My main rig has about 2TB of storage - Windows 7 box. My wife's main machine (iMac) has about 500GB of storage 1 Macbook Pro 1 Windows Laptop (nothing spectacular) I have a Windows Home Server that backs up the windows machines (3.5TB approx.) and also doubles as storing 'duplicate/raided' back ups of photos and videos. I use the WHS as a shared server (for photos and videos), that both the iMac + W7 machine use to access the main repository. The truth is that I have been meaning to convert all the raw iMovie project files to some 'smaller' size and resolution single video flat files (like .mov or .avi or something) and delete the larger iMovie project files to free up some space. Haven't gotten around to doing that yet though. Do you think this is a good idea? Do you have any suggestions on how I can maintain a relatively high quality versions of my memories - doesn't have to be extremely high quality (as I said, I am saving my images as a 1MB jpeg, not the multi-MB RAW files). I am looking for something similar with the video. Also, any ideas on how to manage the backups of everything. So not only do I want to have a central repository that all my network connected devices can connect to (e.g. including my ps3 for the videos), but I want to have backups of those. Right now my WHS server does a backup of the Windows machines just wonderfully, as does Time Machine for the Mac Machines - but that doesn't include backing up the main bulky files (the videos - I put the pics on my main rig first before moving them to the server, so those get backed up) stored on the WHS server. Also, how do I handle backing up the large videos offsite? I use Mozy for my machine and the wife's machine + plus dropbox for the really important files (documents mainly). How do I do remote for the videos in a sustainable/affordable way? Sorry...I know this is long, just wanted to paint as accurate a picture as I can. Thanks.
