Along with OS X Lion 10.7.2 combo update, Apple has also pushed iCloud beta 5 to the developers. This beta however only works if you update to 10.7.2 (developers’s preview) so if you’ve already got your hands on that, you might like to give this a try too. Please note that this is yet another beta release since iCloud has not yet been released to public. It is intended exclusively for developers so before you proceed, backup your files offline in addition to the iCloud storage.

iCloud Backup

As this is beta software, it is recommended that you do not use the iCloud services to store any critical data or information. If you enable iCloud Backup, automatic backup with iTunes when syncing will be disabled. We suggest you also manually back up your device with iTunes.
