See the message that was sent to this list by Holger 6 minutes before
you posted:
that's a change in tar's exit code in version 1.16 which signals
the fact that
files changed while tar was reading them. This is non-fatal and is
ignored in
BackupPC 3.0.0. If you don't want to upgrade, you can patch 2.1.2:

Re: [BackupPC-users] Strange OSX tar errors

[BackupPC-users] CGI Success!
After two weeks (and then some) I got the CGI Interface working correctly. I saw a note on the web someplace about SELinux needing to be turned off (configured) to allow the CGI from httpd to work correctly. I enable CGI to work from httpd in the SELinux configuration applet. I ran the BackupPC_Admin from the browser and the BackupPC software world opened up! All I can say is, Wow! The interface is fantastic. I've successfully backed up several Windows XP clients and all seems to be working well. I initially tried the RPM that came with Fedora Core, but the Source Installation is the best option, which allowed me to select the Data Directory I set up for backups. I'm running BackupPC on: Fedora Core 4 with a 750GB SATA HDD installed in the server. Windows Clients are using Rsyncd as the Transfer Method. I need to tweak the FilesExclude list to omit Temp Files and Virus Scanner directories, etc., but all is working well. Thanks for great software and for the support from the List. It was much appreciated.

[BackupPC-users] Absolute Symlink Hang
BPC Users,
I'm backup up a remote Linux system using rsync over SSH with BackupPC-3.0.0.
My per-host config file contains:
$Conf{BackupFilesOnly} = [
'/etc',
'/usr/local',
];
Everything works fine unless I put an abolute symlink in /usr/local using
cd /usr/local ; ln -s /var var
Then BackupPC will hang during the backup and it will have to be manually
killed. If the symlink is relative, everything works fine.
Thanks,
Doug

[BackupPC-users] Installing BackupPC on Mac OS X
Hallo all together, as I have seen in the README file, BackupPC seems neither tested on Mac OS X host nor on Mac OS X clients. Is anybody out there who is experienced in installing BackupPC on Mac OS X (10.4.x) host as a server application? If there is anybody, where have I do some (special) adaptations in/on Mac OS X? Exists anywhere in the net a detailed documentation installing and running BackupPC on Mac OS X? Do I need anymore software? (I don´t think so.)

Re: [BackupPC-users] Permission Issues?
Well either way it did not work. I had to force the user and group through /etc/fstab to get the folders to have the user group permission set to backuppc. This got the status page to load, but during backups it would crash as i said in my first email. The logs showed they were owned by backuppc, but maybe some read/write setting were not there? I'm not sure. I formatted the drive and setup the USB drive to use ext3. I would of liked to use NTFS, but eh oh well. If someone else has gotten it to work flawlessly on an ntfs partition, then please let me know how.

yes, sorry, my fault. There's a typo in my patch. You applied the patch
correctly and to the correct file (/path/to/lib/BackupPC/Xfer/Tar.pm).
The patch should have tested $? and not $! ... in context:
if ( !close($t-{pipeTar}) $? != 256 ) {
I would prefer to test these things before sending them to the list, but
it's not really trivial in this case, is it? :). I had copied the comment
from BackupPC 3.0.0 after first applying my patch from memory and then
checking in 3.0.0 if it was correct. Seems I didn't look close enough. I
hope I did this time.

Holger
