Q: Help me backing up mu ipad

Dear sir,

Since i bought my IPad last summer, am doing the backup normally with no problems at all.

But yesterday while am trying to do it, a message appeared that i have no enough storage space, so i deleted my last backup to free up all the space (5 GB). And although it has the whole 5GB free, but still giving me the same message that i have no enough storage space and that i need to either buy more storage space or free up by deleting some data.

Can you kindly and urgently help and advise.

Thank you for your coop.
