SOLVED! MY BOOK WORLD EDITION
You need to chmod 755 the /var and var/lib folders.
You can do this via ssh by using the following:
in a new terminal window type
then enter your password (you will need to do this in order to secure root access to your My Book World)
ssh (the IP address of your MBWE i.e. 192.168.1.10)
Password: welc0me (the o is omitted and replaced with a zero '0')
once you are in, to ensure that you are starting at the root, type 'cd /'
chmod 755 /var
chmod 755 /var/lib
You will then have access to the WD_Backup using the following credentials (however if you changed the password you will have to use the password you changed the user account WD_Backup to)
There was a permissions issue with the /var and /var/lib folders, the timemachine folder resides within the /var/lib container and timemachine needs specific permissions in order to work.
This is fully tested and I can confirm that we have backed up all of our Macs now.
Many thanks to paulmc.org for the information
thanks very much. you were right about SSH not being enabled.
I enabled it and was able to enter all the code into Terminal, but unfortunately I still cannot connect as registered user WD_Backup to the NAS. I'm so frustrated as this has been going on for over 6 months and the boards at WD have not been helpful. Anything else you might be able to suggest?
I'll try anything at this point!
well that code did not work no terminal - but with FREENAS and AFP espcially one needs to restart both the Mac and the server and re-create a new SHARE - for TimeMachine mind you that you must be explicit in your instruction so:
on the server :
exclusive folder for time machine only
enable discovery of this folder
enable timemachine discovery of the folder
goto FINDER on client and do CMS+K and punch in your exclusive path
TimeMachine is finiky and always has been!
