I have no issues now with cloud back up, well it's not cloud any more, as my cloud is a Synology NAS at my brothers house. My film rips backup immediately when they are transferred to my server, all our documents are securely encrypted in the early hours and then also backed up to the Synology NAS. So far my system seems to be working well, and it just happens in the background. When I was on FTTC the cloud back would bring the connection to it knees sometimes as the upload was swamped.
