Sadly this happened to me to, I synced the deletion of my complete music library to all the devices. Lucky my that I had the CDs and download codes from the vinyls, but it was quite some work to get it back. Since then I use NextCloud for calendar and addressbook sync, notes sync and a browser mail frontend if I'm not on any of my own computers.
