I'm migrating some huge virtual machine files from developer laptops onto a central virtual host, but the connection between our office and the data centre is somewhat unreliable.

It looks like a typical copy is going to be >15 hours and I wouldn't bet my lunch money that it wouldn't drop out in that time. How can I set up uTorrent or even Opera to do the copy in chunks so I can confidently let it run unattended?

I recommend BitTorrent Sync. It's portable and very easy to use. And it doesn't require the creation of .torrent files. I successfully used it to copy >100GiB over flaky wireless connections. Another option is rsync, which is very robust and fast. –  Marco Sep 11 '13 at 10:56
    
Yes it will work with utorrent: File --> Create New Torrent --> Click Add File. Pretty much self-explanatory. Other valid ways would be to use Skype since it reports resuming and can dig even through company firewalls. Also, you could FTP it using FileZilla which is a free FTP client and server program. –  Zerobinary99 Sep 11 '13 at 11:08
    
@Zerobinary99 Skype is the worst of all possibilities. It is an unstable piece of software and it is very very very slow. It is not even remotely capable of maxing out a decent network connection. Bittorrents (Sync or traditional .torrents) easily go up to 40-60 MiB/s, rsync runs at the same speed here, but skype transfers consistenly stay below 0.5 MiB/s. Furthermore it requires a GUI and is totally unsuitable for data transfers. –  Marco Sep 11 '13 at 12:01
    
@Marco Agreed. Except: Speed is way faster than what you make it out to be. I'm transferring files through it with 1MBit and that's my max upstream. I also received files with several MBit/s from faster connections. If you had those experiences then your Skype was probably behind a well secured firewall. I also merely suggested it since the author of the question apparently fails at even setting up a torrent with the dead easy to use utorrent and sometimes a less efficient solution is better than one that goes beyond the capabilities of the person seeking help. Also, a Gui isn't a bad thing... –  Zerobinary99 Sep 11 '13 at 12:14
    
@Zerobinary99 Assuming you mean 1MBit/s, that's 122KiB/s and way less than the 500KiB/s I mentioned. I'd be surprised if someone can confirm that a file transfer over skype goes up to several MiB/s, let alone 50MiB/s. –  Marco Sep 25 '13 at 8:29

1 Answer 1

I took @Marco's advice and tried BitTorrent Sync and can report back that I have been using it for a couple of weeks and have found it reliable and simple to use.
