Hi,

I am confuse about making backup using disk utility. I want to know what is the process to make a disk image of the Macintosh HD and then restore the Macintosh HD from the image. I don't want to use the install dvd in the process. It's possible to do all the process from the disk utility?

I want to make this as a prevention if my hard drive fails someday and i need to restore my Mac to the date that the image was made, like nothing happens! Any idea?

Thank You for your help!

Your best bet is to setup a FireWire drive as a time machine backup. Then if you have a failure you can boot with the DVD and restore with the time machine. Otherwise if you want to use disk utility you must boot to another source such as a bootable FireWire or the DVD to make the image of your Macintosh HD because of the locked files the os uses while running.

Sorry forgot to add time machine keeps all of your files current also so you have minimal loss rather that the 6 month old os restore.

So, time machine will restore all the apps?

Time machine will restore the computer exactly as it was at the last backup. If you download an app update that blows up the app time machine can restore just that app to it's unbroken state.

You have to have some type of bootable device to boot to to restore your backup and also to boot to to make your disk backup. If you have another Mac available you can boot in target mode to make your backup.

So,

Using Time Machine is a complete and better option than using Disk Utility?
