Changes

This part is a repeat of part2, except we will be demonstrating how to use the '''find''' command to backup recent changes to files. In this case, we will save date/time stamp information in a file, configure to connect centos2 '''centos1''' to the network, run the '''find ''' command, and prove that the incremental backup worked (showing the files created as a result of the configuration of centos2 centos1 to the private networkVPN).
