Prerequisites:  

– admin account & password  
– AFP-share & server IP-address

1. Boot the Computer to Recovery Mode.
2. Open Terminal in the Utilities menu
3. At the prompt enter: `cd /Volumes`
4. Create a sub-directory in Volumes as a mount point for your time machine share:  
`mkdir TimeMachine`
5. Enter `cd TimeMachine`
6. Enter `pwd`. pwd should show /Volumes/TimeMachine
7. Mount the network share with your admin loginname & password:
 
        mount -t afp afp://adminname:password@ServerIPAddress/ShareName /Volumes/TimeMachine
  If your password contains wonky characters like :@\\/ use [URL encoding][1] to [protect][2] them
8. Enter: `ls -la`. Note the exact name of your sparsebundle.
9. Enter: `hdid /Volumes/TimeMachine/NameOfYourSparseBundle`.
You may enter the first letters of the sparsebundle name and then hit <kbd>TAB</kbd>.
Hitting tab should auto-complete the Time Machine sparsebundle name. It may not look the same as above as it escapes spaces and special characters.
10. After auto-completing the name, hit return. 
If you return to the prompt the sparsebundle has been opened.
11. Enter `exit` and <kbd>⏎</kbd> and quit Terminal.
