Can't be fixed since Samba simply doesn't output the needed data. This is
actually a Samba bug if I recall well :)

Well, I have this problem since April and still waiting for a fix. And
since downgrading Samba seems to be a PITA, can we have an update on
this bug?

Problem still happening with Samba 4.3.11

Thanks!

Title:
  backuppc/smb: BackupPC failes to backup SMB shares after smbclient
  update

Status in backuppc:
  Unknown
Status in backuppc package in Ubuntu:
  Confirmed

Bug description:
  After the current update of samba 4.1.6 to 4.3.8 samba on trusty the
  BackupPC smb transfer is broken.

  Several bugs in smbclient >= 4.1.6 in combination with BackupPC:
   https://bugzilla.samba.org/show_bug.cgi?id=11642 (tarmode is no longer
verbose and ignores verbose flag)
    - patch1 (reenable tarmode verbose, and skip inaccessible files)
https://attachments.samba.org/attachment.cgi?id=11733
    - patch 2 (modified clitar.c for tarmode verbose)
https://attachments.samba.org/attachment.cgi?id=11734
   https://bugzilla.redhat.com/show_bug.cgi?id=1294761 (mis-interpreted
failure of new tar:\d+ lines) (fix: https://bugzilla.redhat.com/
attachment.cgi?id=1111264&action=diff)
