Besides these options, there are many other type of RAID configurations that are possible
using third-party software or hardware. Many external drive enclosures that support multiple
drives include hardware that makes different types of RAID configurations much more efficient.
Restoring Disk Images
A popular way of transmitting large files or applications from one computer to another, especially
over a network, is to create a disk image. A disk image is essentially an archive of a disk
volume that can be mounted like a disk. Occasionally, copies of CDs and DVDs can be stored
and transmitted this way as well. The Restore tab (Figure 6-5) allows you recreate the image file
on a disk volume simply by selecting a disk image, selecting an available volume that the image
will fit in, and then clicking the Restore button. You should be aware that this will often overwrite
the destination volume entirely.
TIP If you work with sensitive data, one thing you can do is create a secure disk image containing
this data and mount the disk when you need to work with the data. Then you can
unmount the image when you are done with it, returning the data into a state of blissful
encryption.
