Summary
Backing up a device is an essential thing to do for every computer and/or smartphone user. You won't lose data if your device is lost or you accidentally delete files. With iCloud Backup, you can back up your device every time and everywhere without a computer. If you have access to a fast and stable Internet connection, you might find no problem in backing up your devices daily. If not, it will take hours or even days depending on your device's storage and it's better if you perform a local backup using iTunes.
