Thnx Torsten, 
 
This worked. I also had to add a sudo for the env command.. 
 
Cheers,

 <pre wrap="">OK, this sounds like access control. Your tar must have the right to 
read /etc.

Try $Conf{TarClientCmd} = '/usr/bin/sudo ...

and in etc/sudoers

apache  ALL=NOPASSWD: /usr/bin/tar

Cheers, Torsten

    <pre wrap=""> Okay but this is LC_ALL=C .. I did try it nevertheless and had the same
issue; same error.

 If i do the same command as root I get the contents of the /etc directory
and the contents of each file. This is pushed out to standard output.

 My feeling is the command works but not when running as apache..

Could you try without "env" in the tar commands? I had the same problem and
for me "env LANG=C" did not work but "LANG=C" did.

Hello fellow backuppc users,

I'm attempting to backup a directory on a linux box with using the
following host config file:

----------------------------------

$Conf{XferMethod} = 'tar';

$Conf{TarClientPath} = '/bin/tar';

$Conf{TarShareName} = '/etc';

$Conf{TarClientCmd} = '$sshPath -q -x -n -l root $host'
                    . ' env LC_ALL=C $tarPath -c -v -f - -C $shareName+'
                    . ' --totals';

$Conf{TarFullArgs} = '$fileList+';

$Conf{TarIncrArgs} = '--newer=$incrDate+ $fileList+';

$Conf{TarClientRestoreCmd} = '$sshPath -q -x -l root $host'
                   . ' env LC_ALL=C $tarPath -x -p --numeric-owner
--same-owner'
                   . ' -v -f - -C $shareName+';

----------------------------------

The command it eventually uses is reported as :

/usr/bin/ssh -q -x -n -l root wind env LC_ALL=C /bin/tar -c -v -f - -C /etc
--totals .

Which works from the cli when logged in as root (after copying ssh keys
to client in question) but not from within backuppc; error:

Running: /usr/bin/ssh -q -x -n -l root wind env LC_ALL=C /bin/tar -c -v -f
- -C /etc --totals . full backup started for directory /etc
Xfer PIDs are now 24504,24503
Tar exited with error 65280 () status
tarExtract: Done: 0 errors, 0 filesExist, 0 sizeExist, 0 sizeExistComp, 0
filesTotal, 0 sizeTotal Got fatal error during xfer (No files dumped for
share /etc)
Backup aborted (No files dumped for share /etc)

backuppc is running as user "apache" and has the following line in
/etc/passwd:

apache:x:48:48:Apache:/var/www:/sbin/nologin

Any ideas on how to get this to work. For security reasons i'd prefer to
keep apache running without shell access.

Thnx in advance,
