I do all of my development in a virtualbox virtual machine. Copying it over and over again to an external for back-up gets tedious and I simply do not do it as often as I should. Ideally I would like to simply be able to shut down my VM, click 'backup' and it will back up the virtual machine to some service.
My vm disk drive is pretty much a 30 gig single file so it would have to work via rsync so as not to be uploading constantly.
I am not very worried about syncing to multiple computers.
It should be relatively affordable, I would be paying for this out-of-pocket.
I would just use dropbox, but I haven't heard of anyone storing a file this size in it, and I've seen it mess up enough that I'm not sure I trust it.
Does anyone have any ideas/experiences to share?
