another hint (because BackupPC_tarCreate is really the better option, as it
restores file attributes as well, handles multiple files with just one
invocation, and gets file names right without having to copy and demangle them
by hand): read the error message. The "files/directories ..." parameter is not
optional. You need to specify at least one file or directory to put in the tar
file. If you want everything, just use "/". Eg.

        ./BackupPC_tarCreate -n 55 -h server1 -s /etc /mail.rc > /data/test.tar

(presuming your share name is really "/etc"), or

        ./BackupPC_tarCreate -n 55 -h server1 -s / /etc/mail.rc > /data/test.tar

(if your share is "/"), or even

        ./BackupPC_tarCreate -n 55 -h server1 -s / /etc/mail.rc /var/log/mail 
/etc/init.d > /data/test.tar

for the sake of having an example with multiple files and directories.

Obviously, you need to use a share for the -s argument that you have actually
configured BackupPC to back up.

Note that the leading "/" in your files and directories is optional
("/etc/mail.rc" and "etc/mail.rc" are equivalent, but "./etc/mail.rc" won't
work). This is also true for the first example: use "-s /etc /mail.rc" or
"-s /etc mail.rc". Inside the resulting tar file, file names will have a "./"
prepended, i.e. they will be named "./etc/mail.rc" or "./mail.rc" respectively.
