Match system boot disc to Time Machine system before restore System
I was upgrading the hard drive in my MacBook Pro, so I started by making a Time Machine backup of my existing drive, which is running 10.6.2. After installing the new drive, I went to boot off my Snow Leopard disk. I couldn't find it, so I booted my machine from the original restore DVD (10.5), and did a 'Restore from Time Machine backup' using that installer. Three hours later, the machine rebooted from the new hard drive to an instant kernel panic.

I then found and used the 10.6 upgrade DVD to boot and do the restore again, and it worked flawlessly.

So, save yourself a matter of hours (plus a hefty amount of frustration!), and use the appropriate install DVD to restore your Time Machine backups!

Match system boot disc to Time Machine system before restore

I can attest to this! Also, DON'T USE TIME MACHINE OVER WiFi unless you have a Time Capsule. I was, and Apple said that it was the reason why I was left with a corrupt backup. On a related note, make sure you have a usable TM backup. Since mine was corrupted and I had to copy all the files manually.

Is that when you are on wifi, or TM is, or either?

This hint almost goes without saying. I'm guessing that it would work fine if you booted from the Snow Leopard disk and tried to restore a 10.5 backup, though.

Problems like this is why I don't use TimeMachine. Cloning your boot drive so it's "hold option bootable" is a much safer alternative. It's easier to restore from, it can be used as a alternate boot drive if the hard drive is toast and do everything the original boot drive can. It can be used to repair and recover files from the original, it works if your Superdrive is dead and one can have many clones of various boot drive states. Perhaps best of all is one can keep a boot able clone off site in case of fire, water, theft, so all one has to do is get another Mac, the investment in apps, fonts, files etc are safe on the latest clone. In the case of malware attack, a disconnected clone sure will come in handy after first erasing the boot drive using the write protected, DVD restore disk>Disk Utility>Erase w/Zero method and then reverse cloning onto the clean drive. A TimeMachine drive, being in constant connection, will likely be pwned along with the boot drive. TimeMachine has some benefits as well that cloning doesn't offer, but can be bypassed with a little self discipline of backing up and making "Save As" file change revisions, making sure of one's Trash contents before deleting. However the two backup solutions should be carefully considered in any backup situation, some use both as the situation calls for it.

Good information in this hint.

A good way to not lose or misplace your Snow Leopard DVD is to create a 10GB partition on your external drive and to clone the DVD to the partition using Disk Utility. The DVD can then be put away, the DVD clone can be booted from by rebooting while holding the Option key, and booting from the clone runs more quickly than booting from the DVD in an optical drive.

Can that be done on another mac and used over a network?

Good to know about that. I'm going to upgrade my HD too, and I was thinking about issues that may happen to restore my system. I was thinking in installing my OS 10.6 and then restore with TIME MACHINE. Is this the correct way to do that?

Good call. ;)

Thanks for the tips on this. I had the exact problem mentioned here. Booted from a OS X 10.5 install disc and started TimeMachine restore after being told by AppleCare senior tech that 10.5 disc could restore a 10.6.3 TimeMachine backup. Restore took over 8 hours using Ethernet. Rebooted and got KP Reboot message. Found this post, found my Snow Leopard disc (that was the hard part). I then booted from Snow Leopard disc, did the restore from TM via Ethernet. Restore took 3 hours and worked flawlessly. Thanks again for the post. Too bad Apple doesn't have the knowledge that the user community does. That being said, I would like to praise AppleCare. Started down this path because HDD was clicking and sometimes not booting. Took it in to Apple Store, they not only swapped out the HDD, but replaced the case (MacBook 18 months old) which was cracking a tiny bit, as well as the keyboard. No questions asked, no additional cost, 1 day turn around.

Just wanted to add a note to this hint, you CAN restore a 10.5 Time Machine backup with a 10.6 DVD.

I had to do it this weekend on my Mac Pro when I couldn't boot the 10.5 DVD because the video card I'd added wasn't supported by the version of 10.5 that came with my Mac Pro.

I booted from the SL DVD, selected Time Machine restore and 1 hour later my machine was back and running 10.5.8
