In addition to the birthday calendar, whose backup is not really important, a subscribed calendar is now also saved. Unfortunately, my own calendar, which I use and update daily, is not included in this backup.

Apparently the backup works with all calendars since version 3.29.0. Even those subscribed to from other sources. In my opinion, this is not necessary, but does not interfere.
