3-2-1 rule: 3 copies, 2 different types of storage, 1 off-site copy (e.g., cloud). Apple Support

Windows (choose one or both)

1. OneDrive PC folder backup:
   Start → OneDrive → turn on Desktop/Documents/Pictures backup.

2. File History / Backup:
   Settings → Accounts → Windows backup or Backup → add an external drive → turn on.

Mac (Time Machine)

1. Plug in an external drive.
