· None of the above quite fits
· None of these quite match
· database corrupt after upgrade, all restore attempts fail with corrupt database
· unifi
I would like to add a view things:
Hardware has been running with 100% uptime, NUC Hardware (RAM, SSD etc) hardware checks out 100% ok.
Over the almost 7 years running Roon I had quite a few database corruptions (always caused by updates). But restore was a lifeline.
I have 30 backup generations and so far I have tried 7/30, including the newest and oldest, after completion Roon comes up with corrupt database.
Since I have stopped collecting CDs and I am mostly listening to Quobuz for years now, loosing the database would mean to loose EVERYTHING.
Also: The obscure restore procedure no longer works (as is) on Windows 11. On fresh Windows 11 installation, default policy prevents access to unsecured SMB shares (for very real security reasons).
Time to include a sane backup/restore that operates by exporting/importing by value, instead of just copying out files that may or may not be corrupt.
Hi @Alexander_Holy ,
Thanks for reaching out and letting us know. Can you please confirm the exact error message you see when trying to restore the database, preferably with a screenshot? We’ve enabled diagnostics for your account and I am seeing a strange error I haven’t seen before, I’m escalating this error to the team for review. Please confirm the above while we look into this error.
Please see the guide below for this issue:
Reply to your direct mail: Another restore attempt:
May 15th 19:30 (UTC+2)
ROCK 2.1 build 271
Roon 2.66 build 1658
Stopping Roon Server using Rock Web UI
Connect to Rock share, renaming \ROON\Data\RoonServer to RoonServer_1
Starting Roon Server using Rock Web UI
I connect to the new Roon Server using the Windows App
I press continue when asked for added the Music folder
No thanks for music services
Finish to Audio devices
My local music now gets added anyway. Just to be sure I wait until its finished, takes just a few minutes for my 2020 ripped CDs
I go to settings, backups, Find Backups
I connect to my local SMB share on a QNAP
I select the Folder
The List of Backups is correctly listed
I have Backups every 3 days from 2026 Feb 16 should be 30 total
I select 2026 May 9, Version 2.64 (build 1646) production
Restore is fast, takes just around 2 minutes
The App says to press Relaunch, I click
After a few seconds the Roon Core is listed, I connect
19:53 (UTC+2): The Server comes up with “Hi, Alexander” and the moving logo (screenshot)
at this point, nothing happens…
Its 20:24 (UTC+2). 30+ Minutes have passed.
I close and reopen the Windows app. I comes up with “library loading issue”. (screenshot)
I do a clean shutdown of Rock.

Concerning your KB article:
Still waiting for any suggestions on my corrupt database and the inability to restore those backups
It would be a shame to loose 6 years of data, despite having 10 backups
Day #8 without Roon, no response.
My Roon database has gone corrupt.
I have 10 Backups (and secondary Backup generations), but they all restore as corrupt as well.
I am suspecting a Roon product defect/bug corrupted the LevelDB based KV store (lets not call it a “database”)
My hardware and infrastructure check out 100% ok.
If no one answers or if there is no effective support, what are my options?
As @noris said:
I suspect they are scratching their heads trying to figure out a) the cause and b) the fix…
Personally, I would just start over, but keep the backups for a possible future fix, but it’s your call. Your option 2 won’t affect the situation; option 3 might make you feel better and option 4 is the one to go for if you see no value in keeping Roon.
I have a similar issue, but on a Linux Mint Machine:
My topic was closed without a solution so I would be happy to get further support. I know that a solution can be tricky but it would be nice to hear that someone has my issue on his topic list…
Hi @Stefanshine,
I just looked at your support topic, and have reopen it, I have also messaged Roon’s support team on your behalf requesting feedback.
Hey @Alexander_Holy,
Thanks so much for all your patience here - @Geoff_Coupe is quite correct in that our team is still investigating the issue further, and we haven’t received any updates or additional information to share quite yet. You have our apologies there, as I can absolutely empathize with you regarding not being able to reliably use your existing Roon database.
As soon as we have more information to share, you’ll be notified. We very much appreciate your ongoing patience in the meantime 
Hi @Alexander_Holy,
The team has added a suite of logging to better pin down what occurred to your last database.
If you still have access to your Roon library and wish to give the software another try, we’d be very eager to request a copy of your database so we can pin down what might be causing these recurring library issues.
If you have a Backup of your Roon database from any point previously, please upload it here.
Thank you and our apologies for the deep lapse in communication.
Hi @Alexander_Holy,
It’s been some time so we wanted to check in on this. Were you able to upload any backup of your Roon database through the database uploader so we can take a closer look at what keeps causing the library corruption? If you still have access to your library, please send over the latest copy you have, and we can keep digging from there. Let us know what you’re seeing, and we’ll pick it up from there.
Please note, if we don’t hear back from you this thread may close automatically soon. If the thread auto-closes and you need further assistance, please submit a reopen support request via the technical support help form below and specify that the issue should be reopened. Thank you.
Since it took you so long to contact me my Roon installation and the NUC I have been running it no longer exist. I would have to purchase a new hardware in case I decide to come back to Roon.
I would only do this if there is a convcing story you have fixed your deep problems in data storage and backup. This also means Nucleus is a product best avoided if you want to avoid total data loss.
However I still have all the backups and I have uploaded 26GB of local backups from my two NAS systems.
Let us see if you are able to recover the data.
Hello @Alexander_Holy
Thank you for uploading, and for still being willing to after everything.
We cannot find the files on our side, so we need to ask you to send them again, and to one place this time. Please ignore the older link from August and use this one only:
https://workdrive.zohoexternal.com/collection/nocvrfc5b2ddab55140af8640f1d7ce13291e/external
Please send the entire backup folder as it sits, without picking out individual generations. Roon backups are incremental, so the generations share data between them. A single one pulled out on its own will not restore, and we would end up asking you to do this a third time.
If the upload fails again, please tell us here rather than retrying blindly. We will arrange another way to get the files across.
Data is uploaded.
Hello @Alexander_Holy
We’ve discussed this with our senior QA and development teams. The team is investigating some possibilities here and, as soon as that investigation is complete, we’ll be sure to follow up ASAP.
You have our apologies for the trouble here, and we’ve greatly appreciated your patience as we continue investigating this tricky issue. We’ll be in touch as soon as we can.
