Simple method (that is explained in much simpler detail and all sections have the minimal how-to content in them, as compared to or versus the "Advanced" method guide that we also have to read here, and you can utilize that "Advanced" method guide if you need a further explanation or if you want more help on a particular section, that contains some screenshots) guide for unable to create a new network based (UNC-based) 'Local Backup' device type in NovaBACKUP 21.x and newer.

Issue Summary

In NovaBACKUP 21.x and newer, you might run into an error when trying to create a new network based (UNC-based) 'Local Backup' device (which is also sometimes referred to by the NBK Support and Engineering team as a 'Local FPI' device). This usually happens if there's already an open connection or mapped drive to the same network path—even if it's not the exact same share.

Common Errors You Might See

  • "Invalid credentials!"
  • "Network error! Unable to access this network share."

Why This Happens

The backup software has a limitation in how it adds or edits devices. If Windows already has a connection to the network path (even just browsing it in File Explorer), NovaBACKUP might block the creation of the new device.

Workaround Steps

  1. Disconnect Existing Connections:

    • Use the net use command in Command Prompt to check and remove any open connections to the network path.
    • Example: net use * /delete

  2. Close File Explorer Windows:

    • Make sure you're not browsing the network path in Windows Explorer.

  3. Reboot Your Computer:

    • If you’ve disconnected everything but still can’t add the device, try restarting your PC.

  4. Try Again:

    • After rebooting and ensuring no open connections exist, try adding the UNC-based Local Backup device again.

Important Notes

  • This issue affects both protected and non-protected network shares.
  • Even if you think credentials aren’t needed, NovaBACKUP might still require them during setup.
  • Once the device is added successfully, backups should work fine—even if connections to the path are open later.
