Description Of Issue
Scheduled and manual backups are both failing since mid-June. I’ve tried manual and scheduled backups to local disk and NAS storage where they were previously working and they’re still failing.

I’ve tried shutting down RoonServer and deleting Cache folders, still failing.

Stack trace from latest log:

Any advice?

Hello @Laver, thanks for sharing that trace! Are you able to back up to the Windows 10 core locally by forcing a backup now? Also, if you still have that log file, please upload it here. I’d like to have our team take a look. Thanks!

New backup to local disk on Windows 10 also failed. I’ve uploaded the latest log showing that failure.

If it helps; this system was originally setup as a standard “Roon” box performing both Control and Core roles. I subsequently downgraded / installed RoonServer to run the Core, and installed Roon to get the control UI back.

Reason being is RoonServer is MUCH more stable to be left running. With Roon I’d end up fairly regularly (once a week or so) having to restart the OS as somehow Roon had consumed all available memory.

This PC runs mainly headless so I had little use for running the Roon control UI 24/7.

Any advice? I’d like to migrate my Core to a new machine but my backup is 20 days old. Is it possible to copy the Database folder after shutting down the Core? Or are there other folders to migrate?

Looks like it was an issue with extensions being enabled. I disabled the DeepHarmony extension and just finished a successful backup!

Hello @Laver, thanks for the update! My apologies for the delay, we were on holiday here in the US. I’m glad things are working again, though! I’ll pass this solution onto the team so we’re aware.
