BT CloudBritain’s biggest broadband ISP, BT, has launched a cloud storage app for its home broadband customers.

BT Cloud offers up to 50GB of free storage for existing BT customers depending on their broadband package, although they can upgrade to 50GB, 100GB, 250GB or 500GB of storage. As our sister site Music Ally revealed this morning, BT has launched apps for iOS and Android, allowing users to access files from their mobiles and tablets, while the service also includes the usual range of features such as automatic back up, the ability to share pictures by sending links to Twitter or Facebook and an offline mode.

BT is clearly a big player in the UK market and it will be interesting to see how Cloud fares against existing storage services from the likes of Google, Dropbox etc. Much may depend on how BT chooses to market the service to its millions of existing customers.

BT Cloud does, however, have the possible disadvantage that consumers may not want to be tied to their ISP for their cloud storage.
