A bit hard to guess without knowing the use case and reasoning. Keeping 10 devices synced on a DB that changes often = poor. Protection against some cloud service going down and leaving you stranded seems reasonable. Every server/cloud could explode, decide to charge me $1m a year, or be confiscated by the government and I could still use my phone and then export it to use a 2nd standalone device if I needed to. Even transfer it over USB if needed. But even with 10 devices and a fast changing DB, using rsync or similar sounds pretty painful. Not sure where the ground is that good for rsync, but bad for import/export. I've friends that are particularly security conscious and only sync sometimes, and only over a VPN... but use bitwarden.... just like they would if they used rsync.... which you could use.
