These are backups of the second psql database instance, columbus_webapp. It stores all data that Columbus needs in addition to what Omero holds.

For example the tables stored under the columbus_webapp include login and authentication attempts for users connecting to Columbus from a 3rd party app via the webapp, celery queue information and also contains things like the publishing status, cluster job status and the remote references for the measurements that have been forwarded to Amazon S3 during import for the cluster functionality.

It’s use/relevance depends on the whether or not you are using features like publishing or cluster computing.
