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:
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.
Let’s see a quick simplified example to explain how it works, for this example assume a file on a volume is made up of 4 blocks ABCD:
So on the backup disk, the full version is always the most recent version (for performance reasons), while previous versions are moved out to another location with meta data to link it to the backup version. The above example works the same for multiple disk rotation. It will only transfer the blocks since the last rotation. Now let’s say you wanted to restore to a particular backup version. So the backup logic will go through the steps described above in reverse order, and restore the specific blocks associated with the particular file and version.
Click "Next" at the Getting started page.
Select the drive you wish to backup to. You can back up your data to any external storage drive that supports USB 2.0 or IEEE 1394. Drives of this type offer large storage capacities and the speed that is necessary to efficiently back up your data. To backup to an internal hard drive check the "Show all valid internal and external backup destinations" checkbox. Please note that the wizard will only display drives that do not contain system files.
You can use multiple external storage drives for backups, and you can rotate the drives between onsite and offsite storage locations. This can improve your disaster preparedness planning by helping you recover your data if physical damage occurs to the hardware onsite.
When choosing an external storage drive for your server backup, consider the following when configuring the SBS Backup:
NOTE: The Configure Server Backup Wizard formats the storage drives when it configures them for backup.
Enter a meaningful disk label.
Select the drives you would like to backup. You should back up the system drive (typically, drive C). You will not be able to exclude your system drive from backup. You should also back up any drives that contain business information such as:
NOTE: You can only back up data from a local drive that is formatted as an NTFS file system. Drives formatted as FAT (including FAT32) file systems do not appear in the list of drives to back up.
You should protect your computer that is running Windows SBS 2008 and its data automatically by scheduling daily backups. It is recommended that you maintain a daily backup plan because most organizations cannot afford to lose the data that has been created over several days.
When you use the Configure Server Backup Wizard that is included with Windows SBS 2008, you can choose to back up server data at multiple times during the day. Because the wizard schedules differential-based backups, Backup runs quickly, and server performance is not significantly impacted. By default, Configure Server Backup schedules a backup to run daily at 5:00 P.M. and 11:00 P.M. However, you can adjust the backup schedule according to the needs of your organization. You should occasionally evaluate the effectiveness of your backup plan, and change the plan as necessary.
It is also recommended that you store your external storage drives offsite and regularly rotate them to protect your data if there is a natural disaster.
Once you click "Configure" on the summary page you will be presented the following warning:
You must accept this warning to continue. Please be sure that there is no important data on your target drive, as you will LOSE it.
Once you have completed the "Configure Server Backup" wizard backups will be taken on the schedule you specified. You can also manually launch a backup by right-clicking the server name and choosing "Backup now".
Once you have completed the "Configure Server Backup" wizard you can change the backup options using the Tasks section of the console.
From here you can change:
Here is an example of my backup history. The reason that you see so many failed backups is because I lent my USB hard drive to a co-worker for some testing.
Only the most recent entry will have the complete reason for the failure, previous entries will just have a failure, you must reference the Windows Backup event log for more information. To find the backup event log open Event Viewer and expand Application and Services Logs > Microsoft > Windows > Backup > Operational as seen below:
The scheduled backups created by SBS contain enough information to properly restore a system state if needed, however, there might be a need during troubleshooting to create a traditional system state backup. For more information on system state backups please see our blog post here: System State Backups and SBS 2008.

Great information! Does this new backup handle item by item backup of Exchange or just the store, so that restoration of individual messages, contacts, etc. can be done or will it only do the entire store?
SBS 2008 backups the entire store. You can use a recovery storage group to restore an individual mailbox. We are working on a post on this for the near future.
I hate being negative given how awesome Server 2008 and SBS 2008 are, but I fail to see why neither can do granular file/folder selection for the backup configuration. This doesn't seem insane to anyone? Why did we completely neuter NTBackup and end up with this watered down WBS, which is merely an extension of the lame Vista backup solution which was dumbed down for the everyday user? :( Can this version at least be configured to "Keep # of last backups" unlike Vista, which eats up your entire drive until you delete the backup set?
Any hints as to when the plug-in to all Server 2008 to backup Exchange will finally be released? I can't believe this functionality was removed, how do you backup Exchange in Server 2008 if your 3rd party solution takes a dump?
here's a frustrating thing...
been needing to implement SBS2008 now for almost a month. both dell and hp tell me that they'll sell me SBS2003R2, but that i'll then have to pay roughly 2K to upgrade to SBS2008, even though i'm purchasing well after the announce and RTM dates.
and, both companies say that while they know the launch is wednesday, they won't be shipping the hardware for some time because they haven't qualified it.
this, for a product that's been available in retail channels for awhile now.
you may have the greatest product in the world, but as usual, you've dropped the ball on your customers.
what kind of company would sell you yesterday's product today and then charge you for the upgrade two days later?
yeah. we all know that answer.
Any support for RD1000 drives?
Is it necessary to use the "Safely Remove Hardware " when disconnecting the usb backup drive ?
If so, is there a way to automate this ?
I connected a Lacie EDmini to the SBS 2008 server via a usb port. The drive was formatted and is dedicated for SBS backups, however, when I attempt to configure the backup, the utility will not recognise it as a valid backup drive, yet it appears in 'My Computer' and I can open the drive. Is there a fix for this?
Is it correct, that SBS2008 will NOT support tape devices ?
I recently came across your blog and have been reading along. I thought I would leave my first comment. I don't know what to say except that I have enjoyed reading. Nice blog. I will keep visiting this blog very often.
The only thing I've found that will make WSB work with RD1000 drives is BackupAssist - www.BackupAssist.com - I found some information here:

Hi, We have this version of server and our back ups are failing daily all of a sudden - does anyone know what services need to be running for the back up to work as we recently turned off a lot of services to make the server run faster and I suspect there
might be one turned off that the back up needs to run?? Any help would be very much appreciated thank you
our backups fail when the c drive is full. I am attempting a bare metal restore to a new C drive that has more space and have spent the day not finding this to be easy.
