Thats how we currently do it. However, we're looking at switching to
subversion for the source code to allow things like remote working to be
possible - and it would be very good if subversion could deal with the whole
dataset - rather than splitting it into different areas + utilities to get
the latest versions of things.

The problem there surely is that if a developer is working on source code,
and does an svn commit command, with the binary data now being different to
the repository version, then subversion will want to update the binary at
the same time as the source code. Unless we specifically have it in a
different directory. Already thats starting to get unintuitive and error
prone :-(

Not in a situation where there are remote workers. Backups take time to
recover, and the chances are if the data's changing frequently this
situation will occur too many times (unless the developer is careful, each
time they do a commit! ;-))

I think I know what you're suggesting is pretty much what we'll end up
doing.... just its not particularly ideal. I think if we do choose this
path, we'll have to just store the binary data on an ftp server and sync
with that keeping no revision information apart from manually created ones.

Many thanks for your feedback though!
