Regular backups of the management components ensures that you can keep your environment operational if a data loss or failure occurs.

You implement scheduled backups to prepare for:

  • A critical failure of a management component.

  • An upgrade of a management component.

  • A certificate update of a management component.

In addition, as a best practice, you can take on-demand manual backups in the following use cases:

  • After a successful recovery operation.

  • After resolving asynchronously reported errors in SDDC components.

  • After resolving an incomplete workflow in SDDC Manager.

  • After noting the failure of a scheduled backup of an SDDC component.

  • Immediately before performing a system upgrade.

You can backup and restore SDDC Manager with a file-based or an image-based solution. File-based backup is recommended for customers who are not using composable servers.

For a file-based backup of the SDDC Manager appliance, you can configure a backup schedule and enable task-based (state-change driven) backups. When task-based backups are enabled, a backup is triggered after each SDDC Manager task such as workload domain and host operations or password rotation. You can also define a backup retention policy to comply with your company's retention policy.

By default, NSX Manager file-based backups are taken and stored on an SFTP server that is built into the SDDC Manager appliance. It is recommended that you configure an external SFTP server as a backup location for the following reasons:

  • An external SFTP server is a prerequisite for restoring SDDC Manager file-based backups.

  • Using an external SFTP server provides better protection against failures because it decouples NSX-T Data Center backups from SDDC Manager.

By default, VMware Cloud Foundation does not configure any file-based or image-based backup protection for the vCenter Servers.

This section of the documentation provides instructions on backing up and restoring SDDC Manager, NSX-T Data Center and vCenter Server.
