I need some advice,

I'm setting up a multisite system. It involves tranfering large files (3x10mb at a time or 600x500kb at a time) over not great internet lines.

At the moment i'm using a ftp server and a client at the remote end that checks every minute to see if there's something new.

Is there a better way? VPN seems desirable but I'm worried about transfer speeds - with the ftp the transfer speeds are acceptable, not great but acceptable.

I also plan to do it cross platform - from xp to osx probably.

thanks

Well, a VPN will probably be slower than the FTP, since you have more overhead with a VPN. If speed is already an issue, I'd stick with the FTP solution for now.

@owentb there are plenty of ways of securing and moving files without suffering from poor internet connections. Additionally there are many things you need to consider when moving files around, do they need to be encrypted, does the line suffer from latency/packet loss, are TCP based protocols suffering as a consequence i.e. should UDP be an option?

Can you advise where the two end points are geographically and what daily volume of data is being moved?

thanks for the advice,

the internet connection options available where i am are just not great. i'm looking at moving about 80mb from some sites which need to arrive within and hour probably, 30mb which need to come asap and at some sites upto 1.5gb which should also come asap.

at the moment ftp;ing is working best but i wanted to see what other options are available.

as for the locations - they are a mix of semi urban and urban south africa.

If you're finding that FTP doesn't allow for the throughput you require on your internet connections then you need to look at an alternative delivery protocol. UDP based solutions allow you to squeeze more data through the same bandwidth and can prove to be very effective.

Depending upon your skills there are open source options which would require a bit of work to get running - http://udt.sourceforge.net/

Alternatively you could look at a commercial solution, there are a few around but these are two that I've worked with - http://www.dataexpedition.com/expedat/ and http://www.asperasoft.com/
