Virtual server backups remain a challenge. Is there still a lot of disparity between how backup software products handle virtual server backup?
Yes, there is still a lot of disparity between backup applications. While it is true that VMware provided vendors with the vStorage API, some vendors use the full API while others only use a portion of it. Backup product capabilities vary significantly, depending upon which portions of the API have been used during the development of the product.
Another thing to consider is that the API can evolve over time. That means capabilities can vary, depending on what version of the API was used during the development of the backup application.
