Octavio wants to make a switch to iOS, but he wants to know how he can do backup while on the road and not use iTunes? He wants to also backup his Windows machine with the same option. Leo says that if you want a "trust no one cloud backup" then there really isn't going to be a solution. But a local backup is your best bet for that, and that means a NAS (network-attached storage). Leo likes Synology. It'll backup every machine, except Octavio's iPad. Your only option there is to iCloud directly or through iTunes. But when iPadOS launches this week, you may be able to backup to an external drive locally. Only time will tell.
