Look like Creating a Secondary Storage using Swift create a Region wide Secondary Storage. So in theory if you have a Swift service across multiple datacenter and the Cloudstack database replicated as well, you should be able to recover from a lost data-center.
Although, I doubt I would consider snapshots in the secondary storage as backup because in the case a Cloudstack Account get compromised all snapshots could be destroyed.
