There's a new Cloud sync service that is cross-platform called `Copy`. I first read about this at OMG! Ubuntu (‘Copy’ – New Cloud Storage Service With Apt Name, Linux Clientx).
Copy, a relatively new entry into the ‘cloud storage’ service arena, has a very apt name. Aside from supporting Linux out of the box from day dot the rest of its offerings are, sadly, fairly predictable.The gimmick they are using is that you get 5GB for free, and for every referral you get to sign up You and Them both get +5GB bonus. So you get 5 more GB of space and the person signing up gets 10GB. So if you get 9 people to sign with your reference code up you'll 50GB of space.On the ‘cons’ side the privacy and security policies safeguarding your data aren’t quite as robust as competitors; it can’t auto-sync; and the app gives no indication/notification that a file has completed syncing.
It isn't as integrated as Ubuntu One, and don't know about the long-term standing of the company but I did get an account so I can explore it.
If you are interested, check out the website for Copy.com and if you are interested in getting an account I offer this (my) reference code so you get 10GB and I get a bonus as well.

Outside of the size and cross-platform/distro aspect of it, there is little to it, but I am going to check it out anyway since I do use Ubuntu One, SkyDrive, Dropbox and more and want to see how this stacks up now, and in the future. Of course, if I could get like 100GB for free from Dropbox or UbuntuOne, I would probably not look at any offer like this. I may even be willing to drop my 25GB of SkyDrive.
