How do I ensure a local iPhone backup to Mac won't erase photos not available elsewhere?
Trying to ensure doing a local backup to Mac of iPhone wont erase photos not available elsewhere. How to know what is being overwritten? Normally I backup to iCloud, but finding a lack of reliability in iCloud due to recent loss of data in Calendar app. This made me aware Calendar has no none cloud instances and when rolled back to a date that wipes data leaves no option to recover if data loss becomes worse.
Anyways, as a method to have none cloud backup of my photos I want to back up to my device and trying to sort out if a prior backup contains any content currently not on my iPhone so I know I wont be erasing anything old in a prior back up. Is there a way to know the date range of photos and number of photos in the archives?
