In VMware Tanzu Application Service for VMs, you can back up CredHub and the data with BOSH Backup and Restore (BBR). For more information, see Backing Up and Restoring Deployments in the CredHub documentation.
Ensure you also back up your encryption key. If you do not back up your encryption key, you cannot restore your BBR backups. For more information, see Backing up the encryption keys.
