Restoring image of Time Machine disk I have a raw image of a Time Machine disk made with ddrescue, now I'd like to know if I can hook it up on the Mac and restore data from it.
You should be able to mount the dd image.


Transfer the file to your Mac, add .dmg as file extension and open the file


or


Transfer the file to your Mac, attach and mount it with hdiutil:

hdiutil attach -imagekey diskimage-class=CRawDiskImage -nomount ~/path/to/file


and with the printed device identifier:

hdiutil mount /dev/diskXsY



Then check with tmutil destinationinfo if the now mounted backup volume is associated with the Mac. If a reassociation is necessary check the inheritbackup and associatedisk verbs in man tmutil.
