Symantec Ghost used to be the tool to use, but from what I read, you no longer get a cli-client, unless you are willing to buy the Ghost Solution Suite at least 5 licenses and have another service running on a server somewhere.
So what tool do you recommend for disk cloning and image-based backup.
There are several OSS products, but it isn't entirely clear how well they support NTFS.
I am not really to just get a list of cloning. Instead, I would like to know what tool you use, why you choose that tool, and what you use it for.
After reading the answers I have a followup question. Given the tool you suggest, is it possible, and how easy is it to extract a particular file from the image without having to restore the entire image?
