The backup location has always been on the same Windows 10 shared folder that also has all of my music files. Nothing has changed (the Windows 10 PC acting as a server does not get any Windows updates at all).
To see if it was some kind of trouble with the network I inserted a 16GB USB drive into the NUC. I restarted Roon and the USB drive appeared as available location to use as a backup. But I get the same error with the USB drive. So, what happened?
I pulled the log file, but I donāt see how I can upload it here.
Yeah, I tried that. I even deleted the backup folder and tried starting āfreshā. I still get the same error.
It does the āSnapshotting of Databaseā, then switches to āpreparingā and thatās where it fails.
How do people upload the log files? I kind of think itās going to some examination of the logs to see why itās failing.
Iāve put a copy of the log on my google drive. The entries for the backup should be near the end. Log file
Um, does this mean that you donāt have any backups any more? If so, that a pity, because the symptoms sound as though your Roon database has recently become corrupted - thatās probably why Roon is now refusing to take a backup of it.
Try restoring an older backup and then seeing if you can make a new backup.
Roon now checks for database integrity before taking a backup, so in principle the last good backup should reflect an uncorrupted database, but you could try one slightly earlier just to be sureā¦
Nope, looks like Iām outāa luck.
It refuses to restore from the last good backup.
I get āerror retrieving backup listing (invalid root)ā
I tried selecting different folders and sub folders but I always get the same error.
Seems like the entire backup/restore routine is messed up.
No, the Roon watched folder is another sub folder on this āMusicā share.
Itās like this: \MUSIC\MP3 ā this is the Roon watched folder (I have just double-checked this to be sure) \MUSIC\Roon_Backups ā is the backup folder
Iāve tried every folder to initiate the restore and no luck. Always invalid root.
OK, then weād better wait until @support has had a chance to examine the logs. Once last shot in the dark - rebooting your Core changes nothing, right?
Yeah, rebooting both the NUC and the Windows server didnāt help.
I just exported the database to an excel sheet. So, if I have to start over from scratch I can al least recreate some of details like tags.
Thanks for your help.
Hopefully support will be able to figure out whatās going on.
I just updated Roon to build 1232 - and that made no difference.
Same problem though. My backups all fail.
To recap:
This has been backing up weekly just fine for 3 years.
I normally backup to a windows 10 share.
I also tried a USB stick plugged into the NUC (exFAT formatted) - same error.
I tried backing up to a different share on the Windows server - same error.
I am not backing up a watched folder.
I rebooted the NUC and the Windows server.
I posted the log file earlier in this thread.
The backup starts fine with the message about performing a snapshot. Then when it shifts to āpreparingā it fails with a non-helpful āError backing up databaseā.
Iāve seen other posts here with the same issue. I think thereās a bug.
I performed the update to build 1234 today. I tried the backup again (even though there was no mention of addressing backups in the change log).
I still get the same backup error. I decided to look into this some more. After scanning the log info (below), I noticed that it was getting a SystemIO error on a particular file - abhaaaaa.jpg.
I went and followed that path to that file on the server. The jpg opened fine and it was a picture that I had added by editing the metadata (in the Roon app) on a particular obscure jazz quartet that Roon was unable to add any information on itās own. So, I deleted the file and ran the backup again.
IT WORKED! The backup completed.
For some reason that jpg was crashing the backup. It would have been nice if the backup error could have included some more info, like the filename it was choking on.
