SBS 2011 backup rotation

I've configured SBS 2011 to backup to an external USB drive. I've added a second drive. How do I confiture SBS 2011 to use the second disk or to create a rotation?

This is for regular drives but maybe it will work for you -
Use the Backup Wizard in the SBS Console to add the second drive to the pool. Once added, it will automatically be detected and will rotate accordingly.

I initially attached a 2GB usb drive (Backup 1) and configured SBS2011 to backup to that drive. The Backup history indicates Status: Successful, Backup items: C:, E, Destination Backujp 1. Later I added a second drive (Backup 2) on another usb port. Other than adding the backup drive, I have seen nothing that indicates to me that I have to tell the system to use the second drive. Did I miss something? I also see nothing in the history that indicates that Backup 2 has been used. As far as I know, system is not using Backup 2.

How can I tell if anything is written to Backup 2? How would I indicate to system that I removed one of the drives for off  premisis storage?

While I don't like this answer, this is the offical answer.  Attach all the devices at the same time.
Rob WilliamsCommented:
After configuring the backup you simply add drives. The SBS determines when you switch them and it will indicate in the console each day if the back up was successfully or not. It uses what ever drive is attached at the time. There is no need to ever have multiple drives attached at the same time and doing so will 'confuse' the procedure. Unfortunately the log does not tell you to which device it backed up 1,2, 3, but if it was successful and only one drive was attached you are good. There is no set rotation period it just does an incremental from the last backup on that particular device. The first backup on any new drive takes much longer as it does a full backup.

The backup actually works EXTREMELY well, easily, and makes for very simple restore.

I'm going to remove Backup 1 tonight and execute Backup Now and see if system reports success backing upto Backup 2. Is there a way to view a listing of what is on the disk or do I just have to assume Microsoft has done everything correctly and there will be no problems when the first disaster strikes?

Basically, how can I determine that everything is working.

Rob WilliamsCommented:
The SBS console has basic reporting as to the success of the backup and I find that to be quite accurate. There is more detailed logging under:
Administrative tools | event viewer | Applications and services logs (takes a minute to expand when you click on it) | Microsoft | windows | Backup | Operational

You can also do a test restore of sample files to verify all is working. Use the wizard in the console to do the restore.

And no need to wait until after hours.  The backup is quite unobtrusive, and will not interfer with normal operations.  Of course if your system is max on RAM and CPU then probably should wait.

Backup was actually working, but is works so well that I didn't realize it was working. Thanks to all for the resources. For the next person who has questions about SBS 2011 backup here is what was done:

Server was originally configured with one external USB drive and a backup schedule was set up.

At a later date, a second disk was added to the backup pool.

I watched the backup archive and the system continued to backup to the first disk that I put on the system. I began to question whether I had backup configured correctly for the second disk.

I physically removed the first disk by unplugging the USB cable. I then executed Backup Now.  Backup ran through to completion. While it was running, I ran WBAdmin Get Status in a command window (which was started as an administrator). This window gave me some indication of what backup was doing.

Upon completionm, I then restored a file from the second disk.

Thanks to all!

All of the comments and resources added to my understanding of SBS backup. I've increased the points. Thanks to all.

The full server restore process is incredibly easy to do as well. Much nicer than previous versions or NTBackup.
would like to add a comment here.  I have sbs 2011 running in a virtual environment, and currently have two virtual hard disks configured for server on two separate raid volumes, One resides on the same raid card and one does not.  I added the second virtual drive on a separate raid card after about a week of backing up.  Now after two weeks of successful backups I go and check the volume that I added later.  I can only right click it in disk manager and check space.  Nothing has been written to it.  The first backup disk is almost full, and sbs has not bothered to rotate any backups to my second disk.  
from what I have read so far SBS just knows to do this, but in my case I apparently have a SBS that is not this smart yet.  Please educate me on how to ensure that my backups are rotating to separate volumes using a wizard, because I'm not seeing any options that say anything about rotating in the wizard.   Thanks

You really need to open a new question of your own, but SBS only rotates disk that are physically disconnected and reconnected.  In a virtual environment you best bet is to use external drives, which can be taken off site, and use the following to allow a connection from the virtual to physical USB disk

If you attach multiple disks simultaneously, SBS will not rotate them.
thanks.. that's all I need to know.
