I had a working BackupPC configuration (based on CentOS 7) performing backup of Windows share over SMB, then with minor BackupPC version upgrade it broke in samba part, still operattes normally for linux hosts.

What is interesting, for the "full backup" of Windows host it shows partial backup with ALL FILES PRESENT, but then declares this backup to be aborted.

As I understand it:

• samba performs files copy: OK
• tar extracts all files: OK
• looks like some checks after that fail

Here is version change on my server:

Packages Altered:

    Updated     BackupPC-3.3.0-4.el7.nux.x86_64          @nux-dextop

    Update               3.3.1-5.el7.x86_64              @epel

Here is an error log:

Thank you,
