You need to change directories. This is probably running from your
cgi-bin directory, which the web server doesn't have (or need) write
access to. Is cgi-bin where members, templates, and reviews are kept?
The directory you switch to must be writable by the web server in
order to create backup.tar, or you will have to specify a directory
that *is* writable.
