Hello,
I'm a Network and System Administrator. If provided root ssh access to your file server, I can optimize it properly, as I also maintain an xfilesharingpro based site: idup.in. As for about a script for transferring files, why would you need that? You can transfer files from your site backend. Please see my feedback to evaluate my previous works, and shoot me your reply if you want to talk about this further.
Regards,
Aroel
