When using VCF9 there are multiple places to configure SFTP backup for some components. For SDDC Manager and NSX it is still somewhat the same as in VCF 5 but within “Operations – Administration – SDDC Manager – Backups”. Here you configure your external SFTP and setup schedule and retention periods for those 2 products.
When you want to configure Backup for Fleet Manager, VCF Identity Broker and VCF Automation you need to head to “Fleet Management – Lifecycle – Settings – SFTP/Backup”. Here you also configure your external SFTP site and within Backup you arrange the automatic backup of these 3 components.
Hope this helps keep the searching time down for these settings 🙂
