[BackupPC-users] SMB shares backup issue with smbclient 4.2.10
Just thought I'd share this, in case someone else comes across the same issue. BackupPC-3.3.1-1.el7.x86_64 on CentOS 7.1 After a nightly yum update, which updated smbclient to 4.2.10, all SMB backups of my NetApp filers stopped working with the error below: 2016-04-20 15:00:04 full backup started for share backup1 2016-04-20 15:00:07 Got fatal error during xfer (session setup failed: NT code 0x80090302) 2016-04-20 15:00:16 Backup aborted (session setup failed: NT code 0x80090302) The fix was to change the smb backup command, adding --option=clientusespnego=no, like so: $smbClientPath --option=clientusespnego=no \\$host\$shareName $I_option -U $userName -E -d 1 -c tarmode\ full -Tc$X_option - $fileList Cheers, Otto -- Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.

Re: [BackupPC-users] Issue with samba client 4.1.6 and newer
Thank you for your efforts David.
I've implemented the patch and it works in my environment, backups complete
ok and I can do sucessfull restores. :-)
But as you say, the system thinks 0 files got backed up:
2016-01-19 09:48:39 full backup started for share Backups
2016-01-19 10:58:59 full backup 75 complete, 0 files, 0 bytes, 0
xferErrs (0 bad files, 0 bad shares, 0 other)

Re: [BackupPC-users] Issue with samba client 4.1.6 and newer
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...

[BackupPC-users] Upgrade to CentOS 7.2 broke SMB backups
Hi, Since upgrading to CentOS 7.2 via yum a few days ago, all my SMB backups are failing for no apparent reason, and with very little information. Rsync backups work fine though. BackupPC log shows: 2015-12-18 09:11:04 full backup started for share backuppc$ 2015-12-18 10:29:04 Got fatal error during xfer (No files dumped for share backuppc$) 2015-12-18 10:29:13 Backup aborted (No files dumped for share backuppc$) Traffic monitoring of the BackupPC host show there is continuous network traffic from the client to the host at the usual rate (about 30MB/s) for a backup, so some sort of data is flowing. Checking processes while the job is running shows the following relevant processes, which appears quite correct: 16585 ?S 0:00 /usr/bin/perl /usr/share/BackupPC/bin/BackupPC_dump -f sql01 16588 ?D 0:10 /usr/bin/perl /usr/share/BackupPC/bin/BackupPC_tarExtract sql01 Backups 3 16589 ?S 0:02 /usr/bin/smbclient \\sql01\Backups -U domain/backupacc -E -d 1 -c tarmode full -TcrX - /proc /sys /mnt /var/lib/yum/yumdb /var/cache/yum /run /tmp Any idea where to start investigating this?
