Keep in mind that while you can use litefs or marmot to replicate the database, PocketBase wasn’t designed with multiple servers in mind and some things may not work as expected even if you sync the db files across the servers - custom event hooks, realtime subscriptions and anything else that relies on the core.App instance since technically you’ll have multiple separate applications and there is no builtin mechanism at the moment that will keep them in sync.
