The Image Option by definition is hardware independent since it works at the volume level. For that reason also normal Restore is also hardware independent.  They both work at the volume level and do not communicate to the hardware level at all.

The DR Disaster Recovery Option is partially hardware independent. Somethings like a different video card is immaterial since it will default to the Windows default VGA. Somethings like a different NIC can be compensated for my loading the new driver during the DR process. However due to the extreamly large variety of hardware you really need to test in your environment and work through potential problems.

Thanks,

So with the DR it should theoretically be possible to load the backup to a whole different computer (with the "restrictions" you mentioned)?

Well yes but and it is a big but, CA does not officially support it as a migration tool to move data from one computer type to another. You really have to do your own testing before it is needed. For example one problem I found was when the boot volume on the original system was SAN attached and from the original system to the new system a different HBA was used. The only way I could get that to work was when the driver for the HBA on the new system was installed on the old system when the full backup creating the DR info ran. Now I've not touched DR in a couple of years and have heard it is working better than when I used it. Install it (by default it will run as a live trial if license is not given) and test it.

From what I've seen just about any problem do to an unusual configuration can be worked out, and it is the unusual configs that cause problems a plain white box system to system DR has always worked flawlessly for me.
