Hi!
Backuppc is a backup service that can be used to backup SMB shares with
the help of smbclient.
Unfortunately, a security update of Samba, from 2:4.1.17+dfsg-2+deb8u2
to 2:4.2.10+dfsg-0+deb8u2, broke Backuppc backups and restores
because smbclient was completely rewritten with the 4.2 release.
Backuppc relied on messages output by smbclient 4.1 to confirm that
file transfers were ok.
This patch add new regexps in Backuppc, to provide compatibility with
smbclient 4.2 and more.
Of course, the best would be maybe to patch smbclient, and add some
code that was removed in the 4.2 release, since this update may have
broken other file backup programs.
Best regards,
Ludovic
