    For the last several weeks I’ve been capturing the console logs of our iPhone 6s and 5s (both running iOS 9.2.1) during their daily iCloud backups using Apple Configurator 2 app (available free in the app store).

    50% of the 6s and 39% of the 5s daily iCloud backups have failed to complete on their first try. The entries in the console log include “ Backup failed: Saving asset”, “Backup failed: Encryption key changed”, and “Backup failed: 1 files are missing encryption keys”.

    These daily iCloud backups include both those which I allowed to kick off “automatically” (i.e. 24 hours after the last successful iCloud backup completed) and those which I kicked off manually via Settings>iCloud>Backup> Back Up Now. All of the automatic iCloud backups that failed, did so silently. IOW there was no indication that the backup failed, other than the time stamp of the last successful backup did not change. All of the manual backups that failed, did so with the message “The last backup could not be completed” along with the time stamp of the last successful iCloud backup (Setting>iCloud>Backup).

    Maybe these iCloud backup failures are just a “personal problem” or maybe many iOS 9 daily automatic iCloud backups fail and most people never notice because they fail silently.

    I had the same problem. I deleted last iCloud backup, then turned iCloud backup off, then back on, then manual backup. That backup worked and seems to be backing up at night again.

    Thanks for the reply.

    What were the error messages in the console log when your iCloud backups failed, e.g. “Backup failed: Saving asset…” or Backup failed: Encryption key changed…” or “Backup failed: 1 files are missing encryption keys…” or something else ?

    I just backup to my Mac instead until they fix iCloud backup. Not a big deal to me.

    I have no idea, I never checked. Sorry I couldn't be more helpful.
