Hi! What’s not quite right with Roon?

Tell us what's going on

· I was using a roon neuclus but have now switched to a Grimm MU2. My Roon backup was done on the neuclus with an external USB drive, now when I plug in the USB drive to the MU2, the Roon backups fails and says that the backup directory is not available.

Tell us about your home network

· I use a D-Link AX 1800 router to a Matrix Audio SS-1 Pro to the Grimm MU2

I think you’ll find that the Grimm MU2 can’t backup to a USB drive by design. See:

Unable to Backup Roon onto USB Drive (ref#WFVUVG)

@benjamin I have been getting no where with you last request so I decided to email Eelco Grimm on a whim earlier today and see if his team could give an assist. Long story short was that the USB port on the back of the Grimm will NOT allow for download of a backup and suggested I use a NAS. The good news is that I am several hours into a backup on my NAS. Will keep you posted on how the disconnect from Grimm and the switch to the NUC go. One curious question is since I back up every 4 days t…

The USB port on the Grimm MU2 is for input only (i.e. Read Only). You can have a device there holding your library or music files, but not for backup.

Thank you. This was confirmed by Grimm.

Thanks for all the help guys. What do Grimm owners do to backup if I don’t use a NAS. Can I back up into the internal drive of the Grimm?

Hello @desmond1,

Thanks for following up.

You can try backing up to the internal storage of the Grimm MU2, but we would still recommend using a dedicated backup location somewhere else on your local network whenever possible.

If you don’t have a NAS, the best option would be to create a shared SMB folder on a computer on your network and use that as the backup destination in Roon. You can then run backups manually to that shared folder when needed.

This way, your backup is stored separately from the Roon Server device itself, which is generally safer in case the device or its internal storage ever has a problem.

Thanks.

Do not back up to the internal drive of the Grimm. If the internal storage fails, you’ve got nothing. Offline backups are the best.

I back up to my MacBook Pro. Somewhere in this forum, I posted detailed instructions for mastering the syntax and semantics of backing up to a Mac using the SMB-bladdity-bladdity-blah. Perhaps someone here more adroit at finding old posts could dig that up?
