Is Disk Utility useless for Volume Backups? (unable to scan, mount, restore)?

I recently attempted to create a disk image of an HFS+ Volume (my main OSX partition) using Disk Utility under 10.6.7. Used default config (compressed .DMG). Seemed to work fine until I attempted to "Restore" the .DMG to a new, empty partition. Received errors about no scan info being present, so I attempted to scan image for restore. Scan would not complete, received "internal error." After some research I decided to use terminal to force the restore without running the scan. Failure again, as the system could not mount the image. Attempting to access/mount the .DMG image via double-click also resulted in failure, "no mountable file systems." Are you kidding me? Eh well, maybe the .DMG got corrupted.

 

Finally, I gave up. The image was a compressed .DMG residing on an external drive (HFS+). I decided to do a complete re-install from DVD.

 

Upon re-install, I decided to attempt to image the Volume again, so I would have a base OSX .DMG for restore purposes. So now I'm back to 10.0, clean install. This time I created the .DMG on my desktop, thinking maybe the external was the culprit. Image created fine, but same problems experienced; would not scan for restore, would not mount. So I decided to try it again, this time without compression. Same game. Total failure.

 

It seems that Disk Utility isn't cut out for what I'm using it for. Or is my experience an anomaly? Anyone use 3rd party Mac utilities similar to Ghost or Acronis in the PC realm?
