latest blog entry: “restoring data from macOS addressbook backup”
Today I noticed that one of my contact cards from my macOS's address book
was missing. Since I've got Apple's advanced data protection enabled, there's no way to
rewind the address book via icloud.com. To work around this
I'm regulary creating local backups using address book's “Choose File”
→ “Export” → “Contacts Archive”. I didn't want to simply restore
last week's backup though, I rather frist wanted to know what had
changed between last week's and today's state. I also didn't want to run
a restore operation since I've linked two external carddav accounts
into the address book and I had no idea what would happen to them.
