message that ICloud can't perform backup because of no space?

[kat.hayes]

I just received a message when I turned on my Air2 that there was not enough iCloud space with my account so it was unable to do a backup and it had a button to upgrade my space. I just put some large videos on the iPad, so I'm guessing that is why I ran out of space, because it is trying to back those up?

1. What exactly does iCloud try to back up off the iPad?
2. When does it perform these backups?

Thanks.

Not sure about specifically the iPad, but...

iCloud will back-up just about everything, except for media I believe. You can toggle off whatever don't want backed-up.
(But if you are using an app that has incorporates the media into its own, then that may inflate whatever is backed up for that app)

Back-ups default to happen when the device is plugged in.

Backups occur daily, generally overnight - your device has to be connected to wifi, plugged into a charger, and asleep (not fully off). So basically, if you plug your iPhone in to charge when you go to sleep, the backup should be done before you wake.
