Backup Calendar To Icloud. If you have shared calendars, all sharing information is removed when you restore them. First, you can toggle the switch next to back up this iphone to turn on automatic backups to icloud.
You can restore your calendars and events (along with your reminders and reminder lists) from an earlier version that was automatically archived in icloud. If youโre planning to make the switch from google calendar to icloud, youโll need to export your google calendar events and import them into your icloud account.
