This chapter covered essential maintenance tasks every administrator should be aware of when it comes to a ConfigMgr server. The most important task for each administrator should be properly securing systems in the environment he/she manages. One of the ways to secure the server is to secure data with proper backup and--what is probably even more important--ensuring that this copy is reliable and can be used to restore a server.
A ConfigMgr server could be very useful and can provide a lot of benefits to the company, but, in the wrong hands, it might do a lot of harm, so protecting and securing the server is also important.
