What you said is right, from MACBOOKPro, in FINDER window, I can see two conections
MybookLive which shows all my shares correctly
MybookLive-BACKUP which shows always as failed.
From what I have read somwhere else, the number 2 above is normal (?) MBL does not give direct access to this BACKUP drive. It is seperate from the SHARES I have created.
What I wanted is to make a manual backup of this TIME MACHINE BACKUP stored in the MBL as BACKUP. And looks like there is no way to do that?
You may use Go > Connect to server > yourmybooklivename.local, then mount Time Machine as Guest.
I have time machine setup for auto backups on my macbook pro. I leave the TimeMachine share unmounted so the hourly & daily backups are saved on my local hard drive. One a week, I mount the TimeMachine share (in FInder GO->afp://mybooklive.local, connect as guest and select Time Machine on the next screen). The next backup then does a full backup to the MBL. When done I just eject/unmount the TM share.
