macOS Catalina overwrites iPhone backups
Everything I've read seems to state that Catalina does not overwrite Finder based iPhone backups. However, when I backup my iPhone, I only see one backup in "Manage Backups..." which is the latest backup that I have made. I've checked the backup location as well, and only see one backup there as well. I don't see any settings to archive or keep multiple backups. I have plenty of storage space to keep multiple backups. My phone had a problem recently and I tried to reset and restore, but it said my backup was corrupted, so I want to be able to keep multiple backups just in case. How can I enable multiple backups?
