Presently we use a simple system, centralized and localised storage which is mirrored. Each project has its set of folders, each folder contains standard assets (character, BG, props, sound & dialogs)
does everyone use something along the same lines or do you use any off the shelf or custom software?
The company I do a lot of work for uses a FiberJet network with an Xraid. They store files like you would on any server, with a folder per project.
