I have been running BackupPC 3.3.0 for a few years without trouble. After upgrading to 4.1.1, I am receiving the following errors on backups -

rsync error: rsync failed on file IO(code 11) at exclude.c(1058) [client 3.0.9.6]

** this error is from backup of OpenSuSE Leap42.1 systems with rsync 3.1.0 **

rsync error: unexplained error(code 255) at io.c(629) [receiver 3.0.9.6]

** this error is from backup of Win10 system with cygwin64 rsync 3.1.2 **

Nothing was changed in the hosts configurations.

Let me know if configuration files are needed.

Paul,

Most likely this relates to $Conf{RsyncSshArgs} not being initialized
correctly from the old 3.x settings for $Conf{RsyncClientCmd}.

Can you tell us what $Conf{RsyncClientCmd} used to be (eg, there should be
a copy of the pre-upgrade config in /etc/BackupPC/config.pl.pre-4.1.1), and
what $Conf{RsyncSshArgs} and $Conf{RsyncClientCmd} currently are? Are you
overriding those in the per-client config.pl?

It would also be helpful to look in the XferLOG file to see exactly what
rsync_bpc command is being executed. Could you send the failed XferLOG
file too (feel free to redact host names etc)?

Craig

Craig,
4.1.1 -
$RsyncSshArgs = ['-e', '$sshPath -q -x -l root ', ]
$RsyncArgs = [--super, --recursive, --protect-args, --numeric-ids, --perms, --owner, --group, -D,
--times, --links, --hard-links, --delete, --partial, --stats,
--log-format=log %o i %B %8U %8G %9l %f%L ]

3.3.0 (default and linux systems)
$RsyncClientCmd = '$sshPath -q -x -l root $host $rsyncPath $argList+'
$RsyncArgs = [--numeric-ids, --perms, --owner, --group, -D, --links, --hard-links, --times,
--block-size=2048, --recursive, --one-file-system, --checksum-seed=32761 ]

3.3.0 (Win10 system) $RsyncClientCmd = '$sshPath -q -x -l backuppc $host $rsyncPath $argList+'

I noticed the Win10 system config used the default $RsyncSshArgs which specified 'root' as the user.
I overrode that in the host config.pl to specify 'backuppc' as in 3.3.0.
The linux system backup was looking for a non-existent host.exclude file.
I believe these two errors are the cause of the failures.
However, after all the failures, my BackupPC disk is full.
I need to regain space before attempting any more backups.

I will update this post with the results of the next backup runs.
Thank you for the prompt response and help.
Paul
