After opening "iCloud Backup", iCloud will automatically backup your data for you.
After that, we enter the "Manage Storage", and then you will see the space occupied by the backup and email select to manage the backup of the device, iCloud will display the information of the machine and the time and size of the latest backup and other information, iCloud can back up a lot of things, such as cell phone contacts, photos, mail and even apps can be backed up. You can back up many things on iCloud, such as your phone's address book, photos, email, and even apps. iCloud only displays five backups by default, so to see more, click "Show all apps".
We can choose the data we want to back up, and when we're done, we can choose to back it up. In fact, the process of backing up means uploading the data you want to back up to the iCloud servers, so you can keep your data safe.
There is a special reminder that the backup data will be uploaded to iCloud, so there must be network support, preferably in a WIFI wireless network environment, otherwise it is very consuming traffic, for mobile or Unicom network, the traffic costs are higher, coupled with the backup of data is larger, so it is strongly recommended that we have a WIFI wireless network to backup data.
Finally, if you want to restore your data, it's relatively simple to find a backup point and restore it, and if you need to clear your iCloud cloud backups, click "Delete Backups" at the bottom of the page.
