In attempting to set-up a back-up I got this error message (Failed To Get Authorization To Access Your Account) when I selected the external hard drive connected to my headless Mac Mini. I am using a MacBook Pro to run the headless Mac Mini, running MacOS 10.12.16. I successfully set-up Dropbox as a backup location. No luck with the local drives.
I also have this problem and I can’t seem to figure it out.
The directory I’m trying to do backups to is on my (QNAP) NAS and I’m connecting using Samba. I created a separate user for the backups, created a share to use with Roon and I can access the share as the user I’m trying to do backups with, create directories and such when using Finder. So the user account works, share works, I should have access using the newly created user, but Roon refuses to connect, claiming it has no access 
@support
I’m having a similar problem - I’m running Roon ROCK and it can see the networked drive I want to backup to, but then I get “Failed To Get Authorization To Access Your Account” when I try to run an actual backup?
Just hoping to get some insight on this…thanks…
I’ve shifted this into Support for greater visibility.
Hi @Eric_Luther ----- Thank you for the report and sharing your feedback with us! The insight is appreciated and sorry to hear of the troubles.
Moving forward, to help aide in our evaluation of this behavior you are experiencing, may I very kindly ask you to please provide the following:
An expanded description of your current setup using this link as a guide.
Can you please verify for me that other devices can “write” to the (E:) drive without issue.

Hi, Eric –
Here is more info via screenshots:
• what version of Roon you are running (Settings > About; If you’re running Windows, please let us know whether you’re running 32bit or 64 bit)
• What operating system you are running (Windows 7; OSX 10.9; etc)
• Basic information about the device you’re using (MacBook Pro 2011 w 4gb of RAM; HP Envy laptop w i7; etc).
• Describe where your music is stored – this includes hard drive description and interface type (USB, Firewire, etc. If you are using a NAS or any other kind of network storage, be sure to include the information requested in the Network section below)
• Let us know your collection size (approximate number of tracks)
Describe The Issue
(if you’re having a specific issue or crash)
Describe Your Network
(if you’re having an issue that involves networked components)
If your issue is related to your network, let us know the basics of your network. If your system includes networked storage or audio zones, or Roon running as a remote, be sure to include:
• What router are you using? When did you last update the firmware?
• Is there any other networking hardware involved?
• Is everything wired, wireless, or is there a mix of wired and wireless gear?
• Both my PC and ROCK NUC are connected to the network gateway/modem via cable.
• Can you please verify for me that other devices can “write” to the (E:) drive without issue.
Yup, my PC writes to it just fine…
Thanks for any feedback you might have…
Hi @Eric_Luther ---- Thank you for touching base with me and taking the time to provide the requested feedback, both are very appreciated!
In regard to my question about your ability to write to he (E:) drive…
Q: Can you please verify for me that other devices can “write” to the (E:) drive without issue.
A: Yup, my PC writes to it just fine…
Please do correct me if I am wrong, but my assumption and is that the PC you are referencing in your response is the same PC that is containing the mentioned drive which I would expect to work. My question is if another device on your network (i.e laptop or computer) that has access to the (E:) can write to it.
