I have continued to work with people on getting Time Machine setup and working with your Windows Home Server. I’m calling these new directions version 3 and it’s easier than the last steps that required an applescript. The reason why the applescript wasn’t working in version 2 is that some people had a Windows partition on their Macs, including myself on my new iMac. Instead of fixing the applescript to check for multiple partitions it is easier to just use Disk Utility. Below are the new directions. I have had multiple people confirm that they are working. For informational purpose you can find Version 1 and Version 2 of my directions. Version 2 has some good comments if you have trouble.
You still need have iTimeMachine enabled.
UPDATE: iTimeMachine is no longer active. Use the following command in terminal to enable network disks. The following command does what iTimeMachine did.
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
1. Open Disk Utility in the Utilities folder.
2. Select the Macintosh HD, then go to “File” -> “New” -> “Blank Disk Image”.
3. A box will come up with a lot of different options. The save as name is important as Time Machine will use that name to see if it’s correct. The save as name should be machinename_macaddress. For example mine is jeremy-iMac_0a0a0a0a0a0a. I’m not giving my MAC address but that’s what the 0a stuff is. You can find the name by going to sharing in system preferences or types hostname -fs in the terminal. The MAC address is for the connection that will be used for Time Machine. My laptops are wireless, my desktop using ethernet. Important: You need to use the MAC address for the ethernet card. You can still use wireless after is it setup and running.
4. Name = whatever you want. I called mine Time Machine.
5. Size = Over your total data amount. Right now I set mine at 400g. With Disk Utility you can resize this later if you fill the amount.
6. Partition = Single Partition – Apple Partition Map
7. Image Format = sparse bundle disk image
8. Now create the image. Default is to save to your desktop.
9. Transfer that disk image from your desktop to you time machine folder on the WHS.
10. Point time machine to your WHS folder and start the backup.
If you have questions please leave comments. As always I will try to respond as fast as I can. This is still not supported and I give no guarantee on the safety of your data or reliability of your backups. It works for me and I have been backing my Macs up to Windows Home Server for months.
