I'm almost brand new to UNIX, so I have no idea if how easy or difficult this would be, or if it's even possible.

I've been using FTP to copy a total of about 150gb of files to a remote drive. Since the directory being copied is so large, I've been trying to break it up into smaller chunks based on file names and file extensions, but I'm still running into some timing problems, where I'll have started it first thing in the morning, and it'll only be a quarter or so done by the end of the day, and if I try to start again the next day, it'll start at the very beginning of the directory and just copy files that have already been copied

My question is would there be any way to get around this? Would it be possible to somehow start the FTP session and skip copying the files already in the new drive?

Thanks
