I've done a clean install of 10.8 on my macbook pro mid 2010 15". Trying to set up a time machine on it using an old time machine-hdd. In 10.7: TM saved to External hdd/Username MBP.dmg/backups.backupdb/Username MBP/ In 10.8: TM saved to External hdd/backups.backupdb/Username MBP/ How do I change the location of the TM-backup? I want the TM to continue to backup in the same folder so that I can see the old files when I enter Time Machine. I want to save the backup in the "backups.backupdb" inside the .dmg-image (as in 10.7).
