iMessages, the cloud, and iCloud backup
So I just began downloading the messages on my phone to iCloud with the intention of having them (history included) accessible on my computer too in the event that my phone fails or something. how does iCloud backup play into this? I don't have it turned on because I don't have enough storage space for it to backup everything -- and the only thing im hellbent on saving in an emergency is my messages (since my photos are backed up differently).
Without iCloud backup turned on, will my message history be visible on my computer (same Apple ID) once they are done downloading? Say my phone or computer goes kaput, will I be able to put my message history on any new device if I'm just using iCloud for messages and not iCloud backup?
Thanks
