A faculty member came to me today unable to use her iPad because icloud
was unable to back up her data. We had to force quite her iPad by
holding down both the sleep/wake button and the Home button until the screen turned black and the Apple logo appeared. Once we restarted we were able to see that she had used all her iCloud allotment.
Here is what Apple says about iCloud. Your iCloud account includes 5 GB of free storage for iCloud Mail, Documents in the Cloud, and your iOS device backups. Your purchased music, apps, books, and TV shows, as well as your photo stream, don’t count against the 5 GB of free storage. If
your iCloud storage starts to get full, you can make more space
available by removing items you don’t need to store in
iCloud. For example, you can free up iCloud storage space by not
backing up specific iOS apps or removing the backup of a
device you have replaced. Go to Settings>iCloud>Storage & Backup>Manage Storage, tap
the name of your device under Backups, then under Backup Options turn
Camera Roll to Off. However, it may be best to keep it turned on and use it how it was intended and to rather remove the pictures from the iPad as suggested below:
2. Remove the backed up pictures from the iPad
3. Learn about and utilize PHOTOSTREAM (including its limitations like no videos, only 1000 pics and only for 30 days) to make backing up and saving the photos from the phone easy and simple.
Alternatively, you can also increase your storage by
upgrading your iCloud storage plan.
