I am all for consistency and if it serves a purpose in the cloud and server editions, then leave it. I personally am not bothered either way - the topic just came up because of an earlier poster using the backup in a way thats its not meant to be used.
Maybe it might make sense to rename the backup button “save as” to highlight that you are making a copy of the file and to distinguish it from the concept of backing up. Having said that, I don’t know how the backup button works in cloud and Server versions.
