Symptom
The an alert box with this message appears:
"You have already backed up another Macintosh using this .Mac account. The information in the iDisk Backup folder from the other computer will be completely erased. Do you want to continue?"
Solution
Backup is intended to back up files from one computer to one iDisk at a time. To back up more than one computer at a time, use one of the following solutions:
- Restore currently backed up files from iDisk to the original computer before continuing.
- Back up to optical media (such as a CD-R/CD-RW or DVD-R disc) instead.
- Before backing up, transfer files that are to be backed up from multiple computers to a single computer, then use Backup to archive the files on that computer.
- Drag files you want to back up to a different folder on the iDisk, such as the Documents folder.
- Use a different .Mac account and iDisk for each computer.
Warning: If you have the same user short name on more than one computer, this alert message will not appear. However, even if it does not, you must not attempt to back up multiple computers to the same iDisk. This may result in unpredictable behavior, including either undesired overwriting of previously stored data or failure (without warning) to save the new data.
