I have…

So yeah, there is the (1%?) chance that BackupPC chose to revalidate
the file in question, but I kinda consider that unlikely.
Is this recorded somewhere? I can't find anything in the logs. What
LogLevel would be required for this to show up?

I might have to look into that ;)
Has anyone managed to make BackupPC run from source?
