Once again, duplicati runs fine, takes time to process files, scans everything, takes long to run, but doesn’t backup files. Even if there are guaranteed changes to be backed up.
It runs fine for several hours and then this error is shown in logs, and the backup isn’t updated. Yet there’s no any other indication about the malfunction. Everything seems to be ok, except the data in the baclkup. I’m sure many might once again completely miss that the backup job is broken, which is very dangerous pattern.

I just happened to catch this by change, when checking logs and seeing that there’s something seriously off with the file dates being “backed up”. - Truth is that it looks like it working, but it actually doesn’t.
I have no idea why this is happening, probably related to the update I’ve installed, probably I’ll need to downgrade to some old version.
