Let's say my hard drive in my computer totally dies and is unusable. So I go out and get a new drive. Can I restore my entire hard drive by using time machine?

If this is the case, is it a replacement for using a regular backup program?

Mac OS X (10.4.7)

    You have to insert the system-DVD and restart from DVD. Then you can choose Time Machine and restore whatever you want.

    Yes, you can do this, but the Time Machine drive itself isn't bootable so you'll need to install OS X and then do the restore.

    okay but it can restore all files...

    then I really do not need to do a regular backup anymore right?

    That's the intention, yes.

    Personally, I also use SuperDuper! to clone my boot drive on a regular basis so I have a bootable backup.

    Alright I have a another question. I'm having problems partitioning my drive for Boot Camp because my disk is fragmented because of Archiving my disk before Leopard and deleting lots of stuff. I have Time Machine backed up. So can I erase my drive and restore it from Time Machine defragmented? If this is the case would I have to reinstall Leopard again and then restore from Time Machine, or can I just directly restore from the external disk without reinstalling OS X.

    First, a comment on doing a restore from Time Machine. Yes, you're supposed to be able to reboot with the Leopard DVD, startup Disk Utility, and perform a Restore to any volume mounted using your Time Machine backup volume, and end up with a bootable drive. I consider this a catastrophe alternative, since it will probably take hours to finish, but your data/apps/everything in Time Machine is saved. You'll just have to identify a date to restore to. With SuperDuper! backups, you have an immediately available bootable solution that will have you back to work in minutes from the state of your last backup. Personally, I plan to use both. Time Machine will give me immediate recovery (from last hour) from a damaged/lost/deleted file. SuperDuper! will get me back into action fast if the hard drive fails.

    Restoring ANY file from a backup defragments that file. So, if you have a fragmented hard drive and want a quick (copy speed anyway) way to defragment everything, simply copy the data off drive 1 to drive 2, erase drive 1, copy data back to drive 1 from drive 2, and everything will be defragmented to the beginning of the hard drive. While this defragments files, it doesn't do two things: (1) it doesn't allow you to copy bootable volumes and expect the copy to be bootable, and (2) it doesn't arrange the files on the destination disk for best performance. For this solution, use a product like Coriolis-Systems' iDefrag.
