I decided to play with $Conf{TarClientCmd} variable, which in my case is:
$Conf{TarClientCmd} = '/usr/bin/sudo $tarPath -C $shareName -c -v -f -
--totals';
I tried this way
$Conf{TarClientCmd} = 'cd $shareName && /usr/bin/sudo $tarPath -c -v -f -
--totals';
and this way
$Conf{TarClientCmd} = 'bash -c "cd $shareName && /usr/bin/sudo $tarPath -c -v
-f - --totals"';
but they all fail - it seems like BackupPC uses exec() call and not shell
invocation. So I have written a small wrapper to solve the problem of
wildcard expansion:
$Conf{TarClientCmd} = '/etc/backuppc/tar_wrapper.sh $shareName+ $tarPath -c -v
-f - --totals';
$Conf{TarFullArgs} = '$fileList';
$Conf{TarIncrArgs} = '--newer=$incrDate+ $fileList';
=== begin tar_wrapper.sh ===
#!/bin/bash
if [ $# -lt 3 ]
then
echo "Wrong number of arguments."
exit 1;
fi
cd "$1" || exit
shift
eval /usr/bin/sudo $@
=== end ===
Special cases (like spaces in filenames) should be taken care in configuration
(e.g. './world\ wide\ web/*.ini') - honestly I have not explored such case
closer.
