Once you’ve backed up the contents of a hard disk or CD-ROM to an
image, how can you restore the files?
- If you just need to access specific files, you can double-click the
.dmg file to mount it, then locate the files using the Finder.
If a large image is split into multiple .dmg and .dmgpart
files, copy them all into a single folder before trying to mount the
.dmg. If you have many .dmg files, you can use a utility
such as CDFinder to catalog them so that you can easily find
which .dmg contains the files that you’re looking for.
- To restore an entire CD or DVD, choose Burn Image… from the
File menu and select the image file. This lets you create a copy
of the original disc.
- To restore an entire drive, you can use the Disk Utility program in
the Utilities folder of the Applications folder. (You can
also access Disk Utility by booting from your Mac OS X installation
CD/DVD; that way, you can restore your drive without first having to
install Mac OS X.) First, choose Scan Image for Restore…
from Disk Utility’s Images menu and select the image file. Then
click on the target drive in the list at the left side of the main
Disk Utility window. Click on the Restore tab. Drag the image
file onto the Source field, and then drag the target disk from
the list to the Destination field. When you click the
Restore button, Disk Utility will erase the target drive and
replace its contents with an exact copy of the drive that the image
was created from. If the original drive was bootable, the restored
drive will be, too.
