Apologies if this is in the wrong place but I couldn't see that it fitted anywhere else either
My clients regularly transfer largish files via ftp and everything generally works happily
As they are in an expensive serviced office one client has transferred their internet connection over to a 4G solution to get much faster access without the corresponding bill and generally it works but....
as might be expected their ftp transfers now have many retries and failed transfers. Sometimes the transfer appears to be successful but the resulting file might be a small percentage of the correct file size
Does anyone have any suggestions for alternatives to look at that might work better (more reliably) over the 4g network?

As you're trying to transfer files, I'd suggest looking at rsync instead. I believe that there are rsync versions available on the major mobile platforms now, so this should be an attractive option.

this looks great, do you need a license to operate the pigeon service?

We switched for pigeons two years ago, but had to switch back to slower data transfer since our main concurrent trained eagles to catch our data. I doubt they managed to decrypt them, even that they tried, but we lost a dozen of well-trained poultry and some business because they never arrived at destination.
We contemplated training bats to frighten the eagles, but they would only fly at non-work hours, making the reception of the transfer complicated since we would have had to hire people working at (overpriced) night hours.
We also still have an ostrich : my management was convinced we needed something big and looking mighty, but they did not realize ostrich could not fly. The eggs are great, but the smell is terrible though - I hate when I am on ostrich week.

I was told Ostrich was the green option to replace smart cars, mini's and other small vechicles. All of our execs use them now. I'm unsure about some of the paint jobs.

Pigeon post is also less likely to crash than FTP/Broadband, because the pigeon knows that his life depends on not crashing.

Torrents. Resumable on a 16kb block level, built-in integrity checks, clients are designed for sudden loss of connection. If things go really wrong, a "piece" will fail its hash-check and will be redownloaded.
They're meant for P2P, but they also work fine with 1 seed and 1 peer, essentially acting like 1 server and 1 client. If there are multiple clients, they can limit their upload capacity if they want to.

Gets my vote!
Normally I think of Torrents in the "Pirate Bay" sense - I'd never considered using them for a business system.
But you're right - this is exactly one of the problems they were created to solve.

Absolutely. They take seconds to set up, are actually less hassle than dropbox (where you've only got "public" and "not public"), and fly faster than either European or African swallows. I use 'em for just about everything.
I used to use MegaUpload, until the US government decided that it had the right to confiscate my subscription to the service and access all my confidential customer files. You have no idea how close I came to taking the US government to court (in NL) over that.

I would have thought torrents would be a good way of getting your internet connections revoked by your ISP?
I haven't used torrents at all since anti-piracy three-strikes law came into effect here in NZ.
Sure there might be legit reasons for P2P file sharing, but it must raise a red flag on the ISP servers.
Have I been needlessly cautious?

Well I don't know, I'm not that familiar with how the system works in NZ. I'd hope they'd check the hash against a database of "files that are not supposed to be shared" (which would take quite some effort to maintain), but on the other hand I'd also expect a stupid automated system to be stupid.

I suppose for his case, he should his own (private) tracker and only give the .torrent file/magnet link to the customer or the other way around.
The listing should not be public, the connection should be encrypted (MSE), and usually the government wouldn't know unless they enable deep-packet inspection on for each packet.

I've had good luck with BitTorrent Sync[^]...it's peer to peer, works on all platforms and it's free.

Thank you very much for this suggestion
I have now set this up (pretty straightforward) and it has just completed it's first successful transfer
It took 69 hours to transfer 3.2GB over the 4g connection but it was a good transfer which is way more important
I can also see a number of other benefits in using this as a replacement solution
Cheers Mike

On the Torrent note, there is Bittorrent Sync[^], from the official Bittorrent Labs site.

Did you know there is a name for that?
It's called FedExNet[^] - and it is used for really fast transfer of really big data!
