Problem with backup storage

Hi there,

I've been trying to backup my ipad mini since last week. Yesterday i posted a question to double check if i wont lose any data. Well the thing is, whenever im trying to backup my ipad mini,it says i havent got any storage. I've deleted like 100 of my most precious photos,half my apps,and nearly all my keynote,pages and numbers school presentations.

I'm not liking this because why do I have so less storage left when I only got my ipadmini 1/2 months ago.

If your here to help,then one solution,would be to tell me ways to get more storage APART from deleting data,buying more storage or checking whats "eating" up my storage in settings. Those are the most obvious,in which case,I have found on the internet.

Oh and by the way you know in some forums theres the option of where you can BB code,can we do that on here?

Well thats all and this is very long so PLEASE someone help i will defo give the most helpful answer pointy thingamajig.

Byee
