Backup a specific set of workspaces instead of everything.

It would be nice to be able to backup a specific set of workspaces. This would be helpful in a couple of instances. 1) If we separate part of our organization through sale we could easily backup that segment and they could restore it at their new company. 2) If we are making major changes to a workspace we could run a backup of it first. This would be very helpful as we try to align business processes.
