is your 'local system' linux? then the totally non answer is probably
that you should be using rsync.
if it's a windows machine you can probably still use rsync there by running
it on top of cygwin.
I would also recommend tunnelling the rsync traffic through an SSH connection.

server issues, but perhaps people on the list have some ideas on how to
solve my problems.
I've written a PHP program to "mirror" data on a local drive to a remote
FTP server. It compares file mod times, and only uploads files that are
newer. Works like a charm. Except ---
The remote FTP server is running on a Fedora LINUX system, but I think
any server would present the same issues.
To examine the remote directories, I use ftp_rawlist() to get a
directory listing which I parse. However, the file modification time
does not have a year, and does not show the seconds. I get around this
by "assuming" the year is the current one, and then compare the file
times of the local and remote files ignoring local file seconds. If they
are different, I use ftp_mdtm() to get the real remote time, and then do
my compare. This slows things down a bit, as I have to go to the FTP
server one more time.
Any thoughts on how to get around this? Is there a way to get a better
directory listing?
Second and more serious problem is that when I FTP the file to the
server, the file mod time gets set to the current (file-creation) time.
The same thing happens in a local-to-local file copy using copy(), but I
can use touch() to update the mod time.
Any thoughts on how I might get the remote FTP server to do the
equivalent of touch()?
I realize that these are not actual PHP problems, but maybe one of you
has run across similar issues.
Many thanks.
