After I updated to OS X Lion on my iMac I received an email from the online backup facility Carbonite.com.
Their Customer Support informed me that at this point in time my online backups might not work properly with
OS X Lion as it is currently not supported. It is expected that carbonite will release an update in the near
future to support OS X Lion.
However in the meantime if you are using the online backup facility make sure you use an alternative
solution to backup important files until carbonite is working form OS X Lion.
If you are an existing Customer you will receive updates via emails or check the website for updates.
