You can perform the backup and recovery on windows server 2008 using server backup feature which you can install from windows features. Here I will show you that how you can schedule a backup and then how to recover from this backup using windows server 2008 backup and recovery feature. But you should keep in mind that windows server backup and recovery feature is not a enterprise backup solution because of many limitation.

A wizard will start, from backup configuration option you can choose the type of backup like full server backup, if you choose the full server backup then you are not able to select the same drive/volume where server is installed. From custom option you select the optional files and folders from your computer. Since am I giving to a demo therefore I am choosing the custom option. 
And then choose the custom files and folders for backup by add items button. 
Set the schedule time. 
Next you need to set the destination type which may be a local drive or remote shared folder. I am choosing the remote shared folder and providing it my shard folder path. 
And then finish the wizard.
