ISO is a nearly universal file format that allows a CD to be read in different CD-ROMs, even in a MacOS. It's not perfect, but it comes close, as long as there are no illegal characters in the file and directory names, like slashes and backslashes.
The first thing I do to create an image is run a complete scan of the partition to be copied. I move all the file directories to the top of the partition with the boot-time scheduler built into Diskeeper after the thorough scan. Then I defrag the partition, twice if necessary.
Then I start QuickImage. I choose a predefined "definition file" ... one that I've previously created, with my preferences. This includes the partition to be copied, the destination of the image, the compression level, whether the image should be verified, the files system checked for errors, and if the Disk Writes should be verified. A password for the image can also be added. And the image can be spanned into files that are the right size for a CD-R.
Normally, I choose high compression, image content verification, and span the image into 730,000,000 byte files.
The only thing I change when creating the image is the date. This is what I put in the image description window. I save this change as a part of the definition file for that particular image. I have four definition files; one for each partition in my system.
I always choose the file name of the image to have 8 characters or less, since it must be accessed in DOS.
Note: The image verification doubles the time needed to create the image. But I'd rather be safe than sorry when I really need it.
The first file to be created will be a .pqi file. The other files, if needed, will be numbered in sequence, starting with .002, .003, etc.
After the image is created, I just fire up Nero, and burn each file to a separate CD, with the settings mentioned above. I don't use the Nero Wizard, as creating a new compilation from the File menu gives me more control over the burning process.
Each CD should be burned with no testing simulation, and the CD should be finalized (or closed, so that no further data can be written to the disk.)
The ISO settings I prefer allow a File/Directory name length of 31 characters, a path depth of more than 8 directories, and more than 255 characters in each path. You should also choose the ISO 9660 character set. You'll see a warning that this kind of disk might not be visible in DOS or Win3.1 ... but I have never had any difficulty booting with an image like this in DOS. I don't expect to see Win3.1 again anytime in the future.
I've tested the images in the past, and each one has been viable using this method.
It takes 34 CDs (and most of an evening) to backup all four of the partitions on my main system. Because of this, I only backup the active partition regularly, and the rest every four weeks.
This might be time-consuming, but if I ever have a hard drive go down, I'll lose very little data, if any, and nothing that I consider to be crucial. That's worth feeding CDs to the Plextor one evening a month while I watch some TV, IMHO.
