Most of the Synapse server's state is in its SQLite database. It also has a `media_store` directory that needs to be backed up, though. In order to back up the SQLite database while the server is running, the database must be in "WAL mode." By default, Synapse leaves the database in the default "rollback journal mode," which disallows multiple processes from accessing the database, even for read-only operations. To change the journal mode: ```sh sudo systemctl stop synapse sudo -u synapse sqlite3 /var/lib/synapse/homeserver.db 'PRAGMA journal_mode=WAL;' sudo systemctl start synapse ```
