I'm currently working with the v184.108.40.206beta and I actually find the "cloud storage" feature redundant. I use Dropbox and iCloud on my systems and with the proposed, v4.2, Workspace Location option I can place my BaseCamp data where ever I want it - which, in my case is my Dropbox for now.
Very easy to switch between various "My Collection" databases when I need to as well. When this feature is released, Backup/Restore can be used as just that and not a means to load different databases.
CAVEAT: you may not want to use this feature now as the Developers have said that at v4.2 release there may be breakage with previously saved [Workspace] data.
