I have just lost my laptop, the one that I use to sync all my books. My iBook size is 2.5g an my iCloud account can support 15g.
I tried to backup my iBooks. It shows only 750mb in the backup. When I try to sync my books, iTunes wants to delete them all.
I did not purchase any from iTunes because they don't sell books in my store. What can I do?
My iOS version is 6.1.3, iTunes is at the lastest version.
