Need some clarification from you.
What are you actually asking for? Shadow copy itself, which saves 'selected' files on your system, saving it not to the drive the files are on but to a computer on the network? Are those files to be used on that other computer?
Are you asking how to save ONLY the system files to another computer?
Then you use the word 'data' which can be anything?
If you mean you want a FULL COPY of computer A's drive(s) saved to a computer on the network, then you want something like Macrium Reflect (http://download.cnet.com/Macri.....opDownForm which is FREE) to Norton Ghost (http://us.norton.com/ghost/ which is NOT free). Features vary by product, and there are others too, however, some free versions of some products will not support network devices or scheduled operations.
