It's looks as though it may be more than RegEx issues. I looked the RegEx lines over in Smb.pm and could see some changes were needed, but those alone are not the only problem. It also looks like BackupPC expects a line of output for each file that is transferred with smbtar. The new version of smbclient is only dumping three lines:

Domain=[HOST] OS=[Windows Server 2012 R2 Standard 9600] Server=[Windows Server 2012 R2 Standard 6.3]

tar:322  tarmode is now full, system, hidden, noreset, verbose

tar:800  Total bytes received: 463398359

If you update your Smb.pm per this patch: https://bugzilla.redhat.com/show_bug.cgi?id=1294761 You can get BackupPC to read the new style lines properly. However, without the (missing) output lines for each file being transfered, $t->{fileCnt} is never incremented, and thus is 0 after the transfer.

This results in:

if ( $newStat->{fileCnt} == 0 ) {

       $noFilesErr ||= "No files dumped for share $shareName";

}

I'm having a hard time finding an example of what the tarmode verbose output used to look like, and also how to get (actual) verbose output from the new smbclient.

Thanks for verifying. I hope someone with good regex skills will work out a solution. It seems newer samba versions return results formatted slightly differently, so parsing fails.
There is a config setting:  $Conf{BackupZeroFilesIsFatal} = 1; (Under "Schedule").
I have changed this to '0' so that even tho' I get the warning, the "partial" backup is still saved.

Hi,

For the record I am experiencing the same issue as you are seeing with a BP install on a CentOS 7.2 with smbclient 4.2.3.

Backups are working for the 1st share listed in the job, but BackupPC reports them as failed with "backup failed (No files dumped for share backuppc$)"

A resolution would be most welcome...

Cheers,

Otto

I tried to add the "verbose" option, and I'm still getting a failure: 

Missunderstanding - The verbose option is only ONE of TWO required changes. The second one is to fix the regex of Smb.pm. Because my know how to create a new filter is really bad, I can't publish the solution for this (I've tried, but is still not working). Perhaps someone else has an idea/fixed regex?

OK, I got it now.
So this problem parsing the output of smbclient affect both versions 3.x and 4.x of BackupPC.
Quite a show stopper.
