Well, it seems like it's backing up to Gobbler as you work on the projects, it's project specific and happens from within Sonar and is available in both my locations instantly. As far as I can tell, there's no need to back up your entire heap of projects, only the ones you want available in more than one location. I quite like the idea. I'm tired of lugging harddrives around in the rain and cold weather that we have here, and then worry about them on the pub on my way home after the sessions. Plus, it may actually be cheaper than buying new harddrives all the time. I'm usually doing tracking in one location and everything else in another, having everything available in both places - plus available from the gobbler site when I'm out and about - would be extremely convenient for me. And the transfer protocol seems like it could be useful! I could probably do without Digidelivery.
I've tried to make it work with Box, Dropbox (which I use for other things), Cloud Drive, SkyDrive (ugh) +++ and some paid-for services but most of them turn out to be quite unreliable. Box won't take files if they are too big, SkyDrive don't always upload or download everything. Suddenly you're stuck somewhere missing a file or two. Besides, my projects usually get really big, sometimes with video and such, so to use a cloud based storage service to transfer and store my projects, I need to purchase storage space, so why not do that with a service that integrates in Sonar and then I can leave my Dropbox, Skydrive and all that for personal stuff.
The voucher is still not in my account. I guess it will come eventually. If not I might just purchase the service. On my way to the studio today I picked up a new harddrive since my old one is dying on me. I could have saved the 800,-NOK and spent them at the pub
