I'm trying to start using time machine on my new mac book pro that uses the 10.8.2 osx, but after a few seconds after the backup starts I get a notification saying: the backup disk is not available (see screenshot).

For the backup I'm using a Iomega StorCenter ix2-200 connected via ethernet cable. If I switch the cable to my old computer (os x 10.7.5) then there seems to be no problems.


Could someone help here please?


thanks a lot.


Time machine, OS X Mountain Lion (10.8.2)

    Does the Iomega disk still show up in finder and is still available.. ie you can open it?


    Sometimes setting up TM on a non apple disk is tricky.. have you gone through the whole procedure that iomega should have in the instruction manual.. particularly that the login to the network resource is setup. I suspect you have a permissions issue that TM cannot create the backup because it doesn't have permission to use the disk.

    I bought my MacBook Pro (in June 2011) with OS Snow Leopard (OS 10.6.7) and used my Iomega StoreCenter as NAS for may data and timemachine. All ok. Last year I added the Iomega StorCenter ix2-200 to my network for data files and all worked ok.

    I have now upgraded my Mac with OS 10.8.2 and now my problem starts. Time machine is not working neither with my "old" StoreCenter nor with the ix2-200. The Iomega non protected diskfiles show up in the finder and I can connect as guest and use them. However when I want to use Timemachine I got the same above uerror message as dongiulio (German text, because I am using a German system).

    Is there any possibility to get TM running ? What did they recommend to you ?

    There were major changes made in Lion for Time Machine that caused issues with lots of 3rd party NAS.. in particular the security of AFP protocol was upgraded. Check with Iomega if there is a firmware update for the NAS to bring it up to Lion & ML standard for AFP.
