How to switch backup from iCloud to one drive?

Thanks for reaching out, LadyKarenM.

It sounds like you're looking for a way to move your iCloud backup to OneDrive, or to back up to OneDrive directly. We can help.

What you're trying to do isn't a feature of iPhone backups. The two options you have are to either back up using a Mac or Windows PC using either iTunes or Finder depending on the software involved, or by backing up to iCloud.

If you'd like to submit feedback about this, you can use the Product Feedback link.

Hope that helps.

Take care!
