I have the same setup. But you can avoid the risk of both being in the same place by having a passwords only DB on your pc and a TOTP/Auth only in your phone (or also in PC but with different master pass and usually closed)

But, is there a way to backup and restore? For example, in invididious (Hope devs keep it up with the hard work) you can export all your data to an OPML or json and import it in another instance. For mail it can be done through IMAP.
