It seems like an eternity since the last time I was able to correctly perform a time machine backup on my Western Digital MyBook World Edition (MBWE). On top of that, last year a bought a new mac mini with OS X Lion and my MBWE didn’t support it. So after upgrading to what seemed the buggiest firmware ever, the guys at WD released another firmware (to be precise Firmware Version 01.02.1) and in the release notes it stated: Resolved issue with Apple® Time Machine® incompatibility in Mac OS® X Lion™ update.
The incompatibility was resolved but the Time Machine issue is stil here. So after digging up the web, Apple support forums, WD support community, etc. I finally found something that solved my problem. Actually my problem was that Time Machine was unable to connect to the backup disk with an error message containing “OSStatus Error 2″. So what I had to do was to check the permissions on the MBWE. So the solution is the following (brief and step-by-step)
- SSH as root into your MBWE and check the permissions for
/var/libto apply the correct permissions.
- Use the Time Machine System Preferences to set your backup disk to your MBWE.
In a new terminal window type:
Then enter your password (you will need to do this in order to secure root access to your MBWE)
ssh (the IP address of your MBWE i.e. 192.168.1.10)
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
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/lib folders, the timemachine folder resides within the
/var/lib container and timemachine needs specific permissions in order to work.
If this worked for you please leave a comment. Cheers!
