Mount a Time Machine Backup Disk
Time Machine backup images can be mounted as regular disks using the hdiutil command.
All you need to do is
sudo hdiutil attach <time_machine_file.sparsebundle>
If your Time Machine backup file is on a network share you need to connect to the server and mount the share before you can run the hdiutil command.
It may take some time especially on slow networks or big image files.
