Iphone not backing up
Am using an iphone 5s, ios 9.2. Whenever i want to backup my icloud, it says that iphone cannot be backed up at the moment. It's been going on for about 3 weeks. It happens too when i want to delete a backup, it says that it cannot be done at the moment. Same thing is happening with my mum's phone- iphone 6, ios 9.2. Please help.
iPhone 5s, iOS 9.1
