The pre-migration mysqldump was added so we would have a backup to restore to in case a migration went south. However, given the size of the DB, and the times involved in both writing a backup and restoring from one (which takes days) this isn't very practical. Also, whether there is enough local disk on logstash.o.o where this will be run is not entirely clear. Given this we should just abandon this idea before we begin and just pray that a migration never goes south. (which is probably a terrible assumption given that I've written most of them) If/when we consider the data in the subunit2sql database valuable enough to warrant backing up we can investigate using a real multi-region periodic backup solution.
