Cloud backup appsBacking up your data is important for any iPhone user. This can be done using iTunes and iCloud. iTunes handles the local backups, and iCloud handles the cloud backups. However, not everyone wants to use iCloud, due to concerns about the privacy of data stored on Apple’s servers. It can also be easier to use the same service to back up iOS devices that you use to back up desktop computers, and iCloud doesn’t support Linux or Android.
