Firstly,Thanks all for extending your help.
About, need of our product:: At a very high level, I wish to intercept the
I/Os (essentially Writes) made to a set of files and store the changes in my
secondary storage so that in the event of machine crash user should be able
to reconstruct his/her files with the help of the product. In general
terminology it is Continuous Data Protection (C.D.P.)
My intention is to track the block changes that happen to the files and have
my meta data pointing to the old (changed) blocks so that I get to construct
various versions of the files from my meta data.
As and when plans are crystallized I will have more concrete questions to
chalk down. For now I just need to get started with the Mac OS X Internals
and think of possible avenues to meet my requirements.
Thanks again,

What are the "needs of your product"?
