https://guides.dataverse.org/en/latest/admin/troubleshooting.html recommends regularly deleting entries, which will reduce the size of a database dump in text format. The doc also mentions Postgres' custom format, which offers far better performance and affords per-table restores but performs a table copy. When the custom format is used, to reduce the storage consumed by actionlogrecord one must perform a vacuum full actionlogrecord to write a new copy of the table prior to dumping the database. I'd like to add that last bit to the troubleshooting page.
