I have bought this two months ago and wasn't sure if it is any good as I was using the server backend backup tool before and our host was pretty stable. But within a month things turned ugly as the agency which hosted our website closed down without noticing us and left us with nothing.
I was able to move the website almost flawlessly from the cloud backup (Google Drive) to the new hosting provider. It's even more straight forward than Backup Buddy as you don't need to hassle with an import script: Just install a plain WordPress instance, install the plugin, upload the backup and start migration.
