Cyber Recovery has two code paths when doing NetWorker application recovery one for Linux based servers and one for Windows based servers. In this case, when the recovery ran, it showed that the application type was Linux instead of Windows. When the NetWorker application was added it did not get the correct information to set the apps type to Windows, and instead it was set as Linux and that is the reason why cp -p is used when backing up the /etc/hosts file. In the Window's code path the '-p' option is not used.
