Make your Time Machine drive more useful and more boot-iful
As we've mentioned recently, one of the conditions for a successful bare-metal restore of a Time Machine backup is a Leopard install DVD; you boot from the DVD, choose your backup as source material, wait some number of hours, and then you're back in business. Wouldn't it be good, wondered a tipster at Macosxhints.com, if you could combine the need for a DVD with all that lovely free space on your Time Machine drive and somehow accelerate this process?Enter the "you got your peanut butter in my chocolate" solution: before you set up your Time Machine backups, use Disk
My idle question (and one I plan to test when I can) is if you can actually install a lean system, perhaps with some key utilities and tools, alongside your Time Machine data; boot from that when you need to, and do repairs/recovery before moving on to the restore process. It would almost certainly be safer to carve off a small boot partition (20 GB would be ample) and set up a bare-bones boot environment, but it would be fun to try it all on the same volume and see what happens. Of course, when you hear "fun" and "backups" in the same sentence, turn tail and run.

It would have been great if TimeMachine automatically did bootable backups with restorable checkpoints. Supposedly the upcoming Leopard compatible version of SuperDuper will work with TimeMachine to this possible.
I wrote a OSX backup strategy guide today, and other blogs today are talking about backups and data recovery. Are sunspots killing our drives or something?
Disk Copy? You still running 10.2??

They run when the volume is mounted, one 3.5" drive is a complete bootable (no "DVD" image needed) backup (weekly) of my current system, and i have another 2.5" drive for home folder backups (daily) that i carry with me. And then of course another 3.5" drive with a full bootable backup (~ every 3 months) that is offsite (at my Mom's house) for disaster recovery incase of fire/theft.

Some PPC machines are USB-bootable (more in 10.4 and 10.5 than previous): http://www.macosxhints.com/article.php?story=20060301112336384
All Macs with a Firewire port can boot from an external Firewire device. If the DVD is cloned to the drive, that makes it a bootable device as far as the Mac is concerned.
This could help solve an issue with a system restore from time machine with the Macbook Air....it eliminates the need for the actual CD drive, if you back up to a wired external HDD
January 29 2008 at 5:58 PM Report abuse Permalink rate up rate down ReplyThe advantage of keeping it all on one partition is that space will be used efficiently. The flip side is that Time Machine will take every megabyte of free space and not leave Mac OS X enough room for a scratch disk.
I have a hard drive that Time Machine has been backing up to since early November. Is there anyway to add the Leopard DVD at this point?
January 29 2008 at 3:47 PM Report abuse Permalink rate up rate down ReplyYes, you can certainly do that. Just restore (using Disk Utility) from the Leopard DVD onto the hard drive in question, make sure you leave the "Erase Destination" box *unchecked*, and it should go fine.
January 29 2008 at 4:08 PM Report abuse Permalink rate up rate down ReplyYep, Leo Laporte and gang over at TWiT suggested doing just this not long after Leopard and Time Machine was released. I partitioned my 1TB HDD and used SuperDuper! to create a bootable Leopard install image for just this reason.
I haven't had a need to use the Leopard image yet, but I have booted from it once to make sure it was bootable. I suspect this method will work just fine for restoring a Time Machine backup. It's not going to be a speed demon like using SuperDuper!, but it should get the job done.
I have used Time Machine to restore a drive that died on me a month or so ago. That worked wonderfully. It really saved my backside!
