It is, therefore, not something that someone should play with without understanding what he or she is doing. As a matter of fact, the manual makes good reading for anyone who wishes to understand more about how a hard drive works and how modern hard drive systems can be organized for maximum efficiency. The reference material makes no mention of compatibility with MacIntosh operating systems. A large hard drive, for example, might be divided into two or more logical partitions, each of which is designated with a letter. The size of the image will depend upon the amount of used space on the partition for which you are making an image.
Compression comes with a substantial time penalty, however.
You must number the cartridges, however, and use them in order when you restore the image. Using no compression makes the image creation fast, but it requires substantial media space to store the product. Most back-up programs available today permit you to select the drives, directories, and even files that you wish to back up. You can elect, for example, to back up only your data on a regular basis, figuring that you can always reinstall your applications in the event of a catastrophic system crash. Other backup systems may be even more efficient.
