I did something like that with an overseas connection a few years ago between Houston and France. I did some testing with the connection using various strategies. We tried copying files in native form and also dumped into 'split' zip files. We used a scheduled batch file to do the hard work. The zip file strategy got the best throughput if we were copying all files but our files typically had less than 1% change per 24 hour period... so we used "xcopy /d" (which does not delete files on the remote side which get deleted on the local side).
There was a considerable difference in elapsed time on whether we used xcopy on the sending end or receiving end. I've forgotten now which was faster but I think we did one of the following:
xcopy /a /d /s /e /c /i /q /h /r /k /o /x /y D:\localfiles \\remote\blahblah
xcopy /a /d /s /e /c /i /q /h /r /k /o /x /y \\remote\blahblah D:\localfiles

For future reference, you should look into something like the rsync protocol (usually available by default on linux, but there are versions for windows too).
This is designed to synchronise large files over slow connections, and hence exchanges CPU power for line speed, by hashing the contents of large files and only sending changed blocks within files: thus, if you have a 4Gb file where only 10 bytes gets added every day, instead of transmitting the whole file each time it is updated, it will only sync the block(s) that contain the changed bytes.
I've used this to keep many Gb of data backed up off-site when I only had a 512k upload speed to do it. The initial backup can take a long time, but once its done...

We were not interested in continuous updates, but periodic updates upon demand. My understanding of rsync is that it runs continuously.
Also, we weren't dealing with large files, but a mix, mostly small files.

Fair enough. My experience is that rsync still works well. You can schedule when it runs easily enough - backups were only done at night to avoid loading the slow broadband during the day when it was in use for news feeds etc.

We work using remote desktop (Germany <-> Asia) and it goes pretty well.
For many small files is good enough. For big files is a PITA though.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.

Have you considered using Dropbox or one of the other "cloud" drives? They keep the content synchronized pretty continuously.
|

Second option in the original post.
The server has an inbuilt "dropbox" like software that allow that.
Thank you!

RDP is an excellent tool BUT if you decide to allow the remote working then have an FTP Server (I use FileZilla) at the hosting end and use something like "winscp" to feed the modified files back
winscp runs a sync across the ftp protocol and therefore only transfer modified files and can be run multiple times to make sure that transfers aborted due to PC restarts get completed
you can run over ssl/tls and providing you have decent usernames and passwords then it would be reasonably secure
for added/alternative security factor in a VPN
FileZilla would also allow you to set different transfer rates for different times of day so that the DSL wouldn't be maxed out at busy times

I'll have to look for the VPN thing (which sounds good when it increases security), but, the RDP (VNC, TeamViewer, the one that comes with windows...)... will help a lot and then, no files need to be stored into the remote computer as everything will stay in the server always...
Thank you!

If they're not tech savvy, then they're probably using windows (you didn't say), so I'd suggest OneDrive if the files have to available locally to the user. With that, the files are locally cached and automatically synced to the cloud as they are changed. Just don't let the user put files elsewhere on their system, so maybe move all the microsoft directories to it. You'll get all their personal crap too, but hey, they're getting free backups of their person stuff, so they shouldn't complain.
If the files don't need to be local with the user, then I agree with others -- have them remote desktop into a system at the company. That way you limit their person stuff, and you get to control what's installed on that machine, when (if) its virus checked, etc.
If they're using a fruit, then you'll have to find an equivalent for that OS.
We can program with only 1's, but if all you've got are zeros, you've got nothing.

Nah, the remote option will do it...
Even the onedrive, google drive... options are there, there's too much data and it will be much easier to handle it by remoting.
Thank you!

I'd be impressed if an unsavvy user managed to touch 3 GB worth of files faster than it could be backed up.
If they will alter 3 GB worth of files every day, and you need them backed up every night, and they can turn off their computer, then there really isn't any choice -- the files have to live on a server you control at your company or you won't reliably have backups of them.

Non tech-savvy people have strange super powers that grant them the ability to destroy everything in seconds...
You know... like leaving a bottle of tequila on the backspace key of a computer... 
|
|

|

True. And there's far better places for that bottle of Tequila, like filling our glasses, something a lot of non tech-savvy people do seem to understand 
Good luck with the backup strategy for that user. Something tells me you're going to need it.. or a lot of that said Tequila

It's a good suggestion, but given there will be only two positions... all the sending/receiving would be done between two computers so the p2p magic would be reduced to a kind of dropbox... and this solution is already in the server the company has.
Thank you!

Too much suing.

I'm split on this one. I mostly agree with you. But, there is a reasonable expectation that parts of the plane won't fall apart in flight and injure you. For Pete's sake, the thing could have come loose during take-off or landing and smacked someone in the head...
After reading the article however... When the parent says 'The entertainment unit kept falling down, and to entertain a two-year-old you have to try to keep that TV up' then clearly the parents are to blame as well. Falls once? Maybe it wasn't fastened in securely... Put it back up, carry on. Second time it falls? Seriously, don't risk your kid's safety. Switch seats, notify an attendant... Anything except put it back up and act like everything's going to be alright.
The airline is negligent in this case, sure, but $200k for a situation the parents could have easily avoided? That's just ridiculous. Pay for any hospital fees and post-op care and call it even. Parents need to learn their lesson on this one.
