Can I just reset and start over? Prior storage drive completely corrupted

So, the hard drive array I was using as my backup target is completely corrupted. I want to just throw all that data away and start over. I build a fresh array with new drives, and I just want to start over. What would I need to do? Uninstall and reinstall the server? maybe just remove all the clients and add them back? There doesn’t seem to be any other reset function.

I want the server to forget about all the old data and just start over with new full file and image backups from scratch. This is just for my home network with my laptop, my wife’s laptop and the kids’ two laptops. just those 4 machines.
