How does Apple's mobile phone store things in the storage space of icloud?

Find "Settings" on the phone desktop and open it.

In the setting interface, find "iCloud" and click Enter.

In the iCloud settings interface, you can see the options of photos.

I suggest you check all the options, or you can check them according to your own needs.

You can use icloud to back up your iphone. When this function is turned on, if the iphone is plugged in, locked and connected to wifi, the camera film, account number, address book, reminder events, settings and so on will be automatically backed up. It is equivalent to Apple designating an account for each iphone user in the background, and the data on your iphone or ipad is stored in this account. The capacity is 5G, which is free, but if it exceeds 5G, it will be purchased separately.

It is different from computer backup. When the computer backs up the iphone, you must connect the computer with a data cable and open the software itunes, and "icloud" will be completed automatically. When your iphone is lost, you can remotely erase all the data on the iphone, but the data stored in the "icloud" account is not affected.

When you buy a new iphone, you can choose to restore from icloud. After restoration, you will find address books, text messages, emails, memos, photos and so on. On your original mobile phone, it will return to your mobile phone one by one, and even all the settings of your mobile phone are exactly the same as the original! It seems that "photo stream" can only be saved for 30 days in icloud, and "housekeeper" only backs up photos and videos, not accounts.
