Hi Mauro,

Setting BackupZeroFilesIsFatal to 0 might be dangerous. It is configurable for 
a 
reason. Think about what happens in the following scenario:

- BackupZeroFilesIsFatal is set to 0.
- On "/srv" you have mounted a disk or something.
- Suddenly the mount disappears due to you "fat fingering" the configuration 
(remember that human errors are the most common errors) or faulty hardware or 
something else.

Now when BackupPC comes along and wants to backup "/srv" it does that without 
complaining, even though it contains no files. Depending on the schedule and 
retention settings you might have lost your backup completely. Especially if 
this continues for some days/weeks and you don't notice it.

So the recommendation is to leave BackupZeroFilesIsFatal at 1. Don't add "/srv" 
to the backup until there is data on it. If the client machine has other 
directories you are backing up and if "/srv" is a dynamic mount that sometimes 
isn't used, I would recommend that you create a separate host alias in which 
you 
backup only "/srv".
