Theoretically, if there was some glitch in iCloud that resulted in the mass deletion of things like Calendar, Contacts, Reminders, or Notes data, could data that be recovered from a Time Machine backup? My Photos are safe because I use "download originals" to my Mac and I know I could always recover "Photos Library.photoslibrary" from Time Machine. I'm not so sure about the other iCloud data though. Is that data also stored locally on my Mac and if so, where in MacOS is it and is it recoverable in the event of an issue?
