Backup: Requires Internet Connection and .Mac Membership When First Opened

.Mac membership authentication takes place when you first open Backup in order to make sure you have a valid .Mac membership. .Mac membership authentication is also required when you back up to your iDisk.

If you change the backup destination to CD/DVD after authenticating your .Mac membership, the next time you open Backup the authentication process is not required. You don't even need to be online to back up to CD/DVD. However, if the destination is changed back to iDisk, you will be required to authenticate your .Mac membership again.

Note: If you open Backup after the first authentication, you will see an alert box with this message: "iDisk Server is Unreachable. The iDisk server is either unavailable or unreachable. Please try again later." The options are to select "Open Network Prefs" or "OK". If you click "OK", Backup will open with CD/DVD selected.
