How can I manage iCloud Backup?
Use icloud for contacts, not photos. Photos take up a lot of room on icloud. Do you have itunes? Assuming so - create a backup on your PC-- you will be given an option upon plug in to backup "now" ? If you aren't you can go into your settings and do a complete backup now - make sure you have ticks next to each item you want backed up. i.e. photos, apps etc.
