Assuming FTP is actually the protocol you want to use, by all means use Net::FTP.

You can find documentation on installed perl modules by typing perldoc ModuleName, in your case perldoc Net::FTP.

It says (amongst other things):

SNOPSYS

use Net::FTP;

$ftp = Net::FTP->new("some.host.name", Debug => 0)
   or die "Cannot connect to some.host.name: $@";

$ftp->login("anonymous",'-anonymous@')
   or die "Cannot login ", $ftp->message;

$ftp->cwd("/pub")
   or die "Cannot change working directory ", $ftp->message;
[download]

...

put ( LOCAL_FILE [, REMOTE_FILE ] )
           Put a file on the remote server. "LOCAL_FILE" may be a 
           name or a filehandle.
[download]

Personally, i'd probably use scp instead. It's much more secure, and with a properly configured key pair, all you need to do is

scp -r localdir remote.host:/remote/dir
[download]
