I would like to backup the OS for future use and have leant that
Ghost
is commonly used for this purpose. Can some experience users

how to accomplish it and any minimum hardware and software in
need.
No, it doesn't backup "the OS," it backs up the entire drive (or
partition).
If that's what you want to do, it comes with a manual and help
files that will tell you how to do it.
Regarding hardware, many people back up to a second drive or
(even worse) a second partition on their only drive. But I don't
recommend backup to a second non-removable hard drive because it
leaves you susceptible to simultaneous loss of the original and
backup to many of the most common dangers: severe power glitches,
nearby lightning strikes, virus attacks, even theft of the
computer.
In my view, secure backup needs to be on removable media, and not
kept in the computer. For really secure backup (needed, for
example, if the life of your business depends on your data) you
should have multiple generations of backup, and at least one of
those generations should be stored off-site.
My computer isn't used for business, but my personal backup
scheme uses two identical removable hard drives, which fit into a
sleeve installed in the computer. I alternate between the two,
and use Drive Image to make a complete copy of the primary drive.
