Here on Connect, under Endpoint Management, go into the Backup and Recovery forum and seek advice in there, as they will be able to give you the full picture on what is available and how you can use it to give you a reliable server recovery solution.
Yes, you can use Ghost with WinPE to make images of the server, but it does mean that the server needs to be taken down and rebooted into WinPE, so your images will stop being up to date as soon as the server goes back into service and files start to change. It is also a time consuming process.
With a solution designed for server backup, you can perform automatic full and incremental backups which are more current and require a lot less of your time.
There are also similar products from companies such as Acronis which again can take backups while the server or workstation is running. I use Acronis TrueImage on my Windows 7 workstation and it is really an install and forget program.
