SBS 2008 leverages Windows 2008 backup technology.  SBS also includes a wizard to configure scheduled backups. It also provides a centralized location to monitor the status of past backups and other related configurations.

SBS 2008 can backup:

  • Files and folders
  • System State
  • Exchange
  • WSS (SharePoint)
  • SQL 2005 Instances
  • MSDE Instances

With the new SBS 2008 backup solution, the concept of full vs. incremental is very different from what you are used to with previous versions of NTBackup.  With SBS 2008 every backup is incremental from a storage point of view, but full from a restore point of view.  Basically backup stores the changed blocks on the source, and maintains a meta data on which blocks changed per version. On the recovery side you can always recover the full version. The recovery logic looks at the meta data, picks up the correct blocks based on the version and adds them up. This same principle works for Exchange. The exchange recovery logic knows which files it needs to recover for the exchange databases. Then based on the version it picks up the specific blocks from backup drive, adds them up and restores it on the system.
