Iphone use OneDrive to backup files, Contacts, Photos
I recently bought an Iphone and changed from my Windows Mobile devices. I was using Android prior. Today, I received a message that something called, Icloud, has storage almost full. I checked and saw I was inadvertently backing up files to this service. (I'm assuming it is an Apple service?) I went into the settings and deleted it. Question, however, is how do I ensure all my files, photos, and settings are backed up to OneDrive For Business. We have this setup and I have 2TB of storage on OD4B. Also, it is encrypted and approved for our corporate use.
Any ideas?
