iMessages not included in iCloud backup if Messages in iCloud is on?
This has been discussed before, but I'd be happy for a recent confirmation.
I friend of mine accidentally deleted a valuable iMessage conversation from her iPhone. As she has a recent iCloud backup from before the unfortunate incident, my first thought was that an erase and restore would get her messages back. But as she had Messages in iCloud turned on, it seems like no messages are included in the backup. Apple's resoning would be that it'd be redundant - except for the case where things are deleted by mistake (which usually is a pretty big reason for backups).
Is that the case? An accidental erase - gone forever?
