Situation definitely improved after applying the patch (now we see a list of files passing via sambe), but backup still gets marked as bad:

Got fatal error during xfer (No files dumped for share C)

Not saving this as a partial backup since it has fewer files than the prior one (got 997 and 0 files versus 997)

Thank you,

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,

Did you also upgrade the version of samba, or any other packages on the backup server at the same time?

Adam
