Canonical's cloud storage provider, Ubuntu One, today launches its referral program. The Ubuntu One referral program allows users to earn free cloud storage by spreading the word and inviting family and friends to join the service.
As of today, when users open their Ubuntu One web dash they will find a referrals invite link. By sending the link to friends and family via email, Twitter or Facebook, users will be obtaining an extra 500MB of free cloud storage for each person who signs up for an account.
Ubuntu One already offers an initial free 5GB when signing up, plus an extra 500MB offered for both the referrer and referee. The new user can then go on to refer others, giving them the opportunity to gain bonus cloud storage space.
Ubuntu One users will be allowed a maximum of 40 invites, potentially earning them an extra 20GB of free cloud storage on top of the 5GB when signing up. More information can be found at Ubuntu One's blog.
Free cloud storage has proven to be a rather competitive area, with well-established Dropbox promoting a similar 500MB referral offer. However, Dropbox's free storage service offers a limited 2GB.
Other competitors on the free cloud storage market are Microsoft SkyDrive (offering a respectable 7GB of storage) Apple iCloud (5GB of storage for owners of Apple products), Google Drive (5GB of storage) and CX (gifting 10GB of storage).
