Hello @Moses Abraham, Densinghdaniel ,
Thank you for reaching out to Microsoft Q&A Platform.
Based on your previous thread, i believe you were able to configure the backup successfully for SAP Hana workload using azure backup and now you would like to trigger an adhoc backup?
If i am right, the right usage of az cli command for an on-demand backup is
az backup protection backup-now --container-name MyContainer --item-name MyItem --resource-group MyResourceGroup --retain-until 01-02-2018 --vault-name MyVault --backup-management-type AzureWorkload
To fetch the info for optional parameters, please refer to https://learn.microsoft.com/en-us/cli/azure/backup/protection?view=azure-cli-latest#az_backup_protection_backup_now-optional-parameters
For example : for --container-name is Name of the backup container.
It accepts 'Name' or 'FriendlyName' from the output of az backup container list command. If 'FriendlyName' is passed then BackupManagementType is required.
Please "Accept as Answer" if any of above helped so that, it can help others in community looking for remediation for the similar issues.
