Hi @karson_kwan,

Have you made backups successfully previously from this Core machine?

How many tracks total are in your database (can be found on Overview screen)?

4

The last backup was Nov 2019, How to see how many tracks?

5

Hi @karson_kwan,

The number of tracks can be found on the Overview screen in Roon.

6

about 61000

7

about 61000

Thanks for confirming, @karson_kwan. That’s not too large, so that shouldn’t cause any issues.

How much space is available on the C drive? Do you have any other location you can try to back up to? Does it work if you use the other location?

9

many space

Hi @karson_kwan,

If you back up to a different location like a USB drive or Dropbox does the same error occur?

11

NAS . Dropbox I have been tried. same issue

12

Thanks for confirming, @karson_kwan.

I think the next step here is to enable some diagnostics on your account so our technical staff can get some more insight into what’s going on here.

However, before I enable this feature, I’d like to ask for your help ensuring we gather the right information.

First, can you please reproduce the issue once more and note the time at which the error occurs. Then respond here with that time, and I’ll make sure we review the diagnostics related to that timestamp.

13

OK, Done . The time is 21 Mar 17:29:36

14

Thanks, @karson_kwan.

Now that I have the timestamps, diagnostics have been enabled on your account. The next time your Core is active a diagnostics report will automatically be generated and uploaded directly to our servers

Once that’s been received, I’ll be sure to update this thread and pass the diagnostics over to the team for further analysis.

15

Sorry I don’t understand received what?

16

Any UPDATE?

Hi @karson_kwan,

I spoke with the team about their analysis here and this is what they’ve found:

Whenever a backup is being made, Roon is receiving this error. It’s hard to say exactly what is causing this at the moment, but something about your specific environment is triggering this error.

The first thing we’d like to suggest is this:

  • Close Roon on the Core machine
  • Navigate to your Roon’s Database Location
  • Find the folder that says “Roon”
  • Rename the “Roon” folder to “Roon_old” IMPORTANT ---- Do not delete this Roon_Old folder. You’ll need to keep this.
  • Restart the Roon App to generate a new Roon folder
  • Try to make a backup with this new database — Does the same error occur?
18

If I rename the roon folder. How to restart the app?

19

Thanks for the followup, @karson_kwan. You can find the existing application file in the Roon_Old folder.
