I would argue that’s the opposite, given how cloud sync works (not Logseq sync), once you have a single file being updated and the in memory state differs from multiple devices, the whole database will be replaced, potentially erasing recent changes.
Main concern is that Logseq sync seems to still have a few rough edges (that’s why I haven’t enabled it), but once there is a database, all the data will live there, instead of having separate files. With separate files if data is lost it will be limited to some data, but with a database, all data is lost at once
Picture me very concerned
