Not quite - on the official images, the entire service is installed to /usr/local/bin/ignition, rather than the ‘exploded’ path we used in previous versions - so the equivalent path would be /usr/local/bin/ignition/data. Not that Ignition as a whole has some limitations with single volume persistence like this; backing up the /data directory will capture the internal database and projects, which is 90% of what you would want to restore, but it does omit any custom JDBC driver files, modules or Python libraries you’ve installed (all of which are in ${install dir}/user-lib/).
