Greetings wise wizard of EE:
I'm helping a friend who runs a window-washing business completely on his iPad... he owns an iPhone, but no computer. He uses the Apple calendar on his iPad, and it is incredibly important to him. He would like to backup his calendar, but didn't know how. I assured him if he was using an iCloud calendar, it would be backed up on the iCloud servers and would be visible on icloud.com. I confirmed that he was signed into an iCloud account on his iPad, and that iCloud "calendar" was turned on. I then checked his default calendar under Settings, and it was set to his iCloud e-mail address... for privacy's sake, let's call it email@example.com.
When I opened his Calendar app on his iPad, and tapped "calendars" at the bottom of the app, it showed that several calendars were available. There were FOUR calendars under iCloud: "Home", "Work" and TWO firstname.lastname@example.org calendars (one colored red, the other blue). I'm not sure (and neither is my friend), how there were TWO email@example.com calendars under the iCloud heading, but I assume these were custom calendars of some type, that he may have created by mistake. Here is where it gets really weird; I logged into icloud.com on my PC, using his firstname.lastname@example.org as the user ID, with the correct password, but NEITHER of the email@example.com calendars were visible on the icloud.com calendar.... just the Apple default Home and Work calendars.
I then set the "Work" calendar under iCloud as the default calendar for both his iPad and iPhone, and so from now on, all future calendar entries will appear on the iPad, iPhone and icloud.com (we tested this, and it worked). However, I don't know how to back up his current iPad calendar, as this mysterious firstname.lastname@example.org red calendar ONLY appears on the iPad. I don't believe a cable sync to iTunes will back up the calendar, as the calendar is normally backed up on icloud.com. I did call Apple support, and the first tech intentionally hung up on me, as the issue was too complex. I called back and the second tech recommended that I upgrade to the latest version of the iOS (he is using version 10), but my friend recently tried this and upgraded to iOS 11, and to his dismay, it WIPED CLEAN his email@example.com calendar, and the only way to get it back was via an iCloud backup.
Whew... here are my questions: does anyone have an explanation as the nature of the mysterious firstname.lastname@example.org calendar, in that it does not appear on icloud.com or his iPhone, and why there are two email@example.com calendars on his iPad iCloud calendar? Finally, is there a way to backup this mysterious calendar on the iPad?
Many thanks in advance and take care,
