- a9s Backup Manager: Add missing configuration
anynines-backup-manager.jobs.backup_fragment.max_attempts. This configuration is only relevant if you have at least one a9s PostgreSQL service instance in your environment with Continuous Archiving enabled. In this case, without the mentioned configuration, backups for these service instances cannot be handled and it leads to failing background workers of the a9s Backup Manager and so to a decreasing functionality of the a9s Backup Service.
