After a discussion with cloud, and some thoughts being shared at T284157, it is clear to Jaime that cloud team will benefit from moving their production network database backups workflow from the old system (mysqldump with bacula predump script) to the new production system (wmfbackup automation).

This will provide many advantages on backup handling and restoring, plus will unify the backup systems into a single one.

The intention is to setup the new backup system on a read only galera host an perform a test for validation.
