If you are unable to delete the Recovery Services vault despite having no backup items, ensure that all dependencies have been removed. Here are some steps to check:
- Verify Backup Items: Double-check that there are no backup items, backup management servers, or replicated items listed in the vault. You can do this from the Essentials pane in the vault menu.
- Check for Registered Storage Accounts: Ensure that all registered storage accounts are unregistered. Go to the vault dashboard menu > Backup Infrastructure > Storage Accounts and unregister any listed accounts.
- Remove Private Endpoints: Ensure there are no Private endpoints created for the vault. Go to the vault dashboard menu > Settings > Networking, and check under Private access.
- Disable Soft Delete: If the Soft Delete feature is enabled, you need to disable it before deleting the vault. Go to Properties -> Security Settings and disable the Soft Delete feature.
- Use Azure Resource Manager (ARM): If you are still unable to delete the vault, consider using the Azure Resource Manager client to force the deletion. Ensure that all dependencies are removed before attempting this.
If you've completed all these steps and still encounter issues, you may want to consult Azure support for further assistance.
