This chapter wraps up the backup and restore approaches for a complete SharePoint environment. Yes, it is complicated and not something that can be done in an afternoon. It is not just the planning and testing that was discussed in the previous chapter, but the understanding of the SharePoint infrastructure.
From reading this and the previous chapter, it can be seen that the skillset that is needed is not just SharePoint, but rather the Microsoft server stack.
The next chapter introduces you to SharePoint out-of-the-box DR processes through SharePoint's Central Administration interface. Both this chapter and the next should be compared together so that you truly understand the DR process for SharePoint.
