    Thanks for posting this… this is exactly what I want do… specifically I want to save my MacBookPro backup to a PC Server that I have running in my house… which is then backed up to the cloud. However, after I past the following text into the terminal…”sudo tmutil setdestination /Volumes/MacBookProBackup”

    I get prompted for the password which I enter…

    and then I get an error saying “No such file or directory (error 2) back up destination could not be set.

    Any ideas what I might be doing wrong?

    Which password am I supposed to use in Step 6B?

    What happens if I boot up the MAcBookPro but the server isnt available?

    Thanks so much in advance for any help you can provide!

      It’s usually happens when Terminal couldn’t locate a disk image on network, most of the time we get this problem because of the “Disk Image Name”, to resolve this problem you can try following steps:
      1. Check disk image name as same as in the command you entering in Terminal, also make sure no spaces in “Backup Disk Image Name”.
      2. If you still get problem then start the whole process again.
      3. Enter your user login password same as your computer password for Terminal-Step 6B.
      If you couldn’t able to resolve the problem, let me know.
      Good Luck!

    How do I do a restore from the PC backup to a Mac after upgrading SSD then fused with HDD?

      April 6, 2015    

      Well in your case i would recommend you new installation of Mac OS, after… just bring your data manually from PC Backup into your Mac.

      However this is a good question, and i believe you can restore your Mac from PC Backup by using a Terminal commands, unfortunately i’m not expert in commands, if you find commands please share in comment box here. Thanks!
