I just purchased a Drobo FS and enabled a TM share on the device. I have previously been using an external HDD with TM to save data, and wish to move the backups.backupdb folder to the drobo FS, continue with my TM on the new device, and throw the external HDD into the Drobo array. I have been following the instructions here under the heading “Mac OS X v10.6: How to transfer your backups from your current hard drive to a new hard drive”, but have hit a wall at step 8. Finder gives me an error saying “The volume is the wrong format for a backup” even though the share is time machine enabled and mounted. Also, I was unable to verify step 4 of the instructions.
Any help on migrating the data for use in the new device would be appreciated
