I think I share you view on the 'Ideal world'. Backup (via Volume Snapshots) is a huge bottleneck in Cloudstack. This is amplified especially when you have a object storage as your secondary storage because it requires two copies (one to an NFS staging area and from there to object storage). And not to mention that all these copies are consuming hypervisor resources. Xenserver's Dom0 is also a huge bottleneck as all the Network and I/O flow through it. So our intention of proposing the "Storage Snapshots" is to give a better way of achiving snapshots while still keeping the original definition of volume snpashots (ie upload to sec storage).
But as Erik pointed out volume snapshots are not backups. They don't work form multi-disk LVM volume groups and dynamic disks. I am all in for a better backup solution which handles these use cases and utilizes the storage's advanced features.
