Backing up to one drive is just silly.  Everyone knows you have to rotate your backups, so why does Windows Backup make this so difficult?  Command-line to the rescue, it’s actually really easy…

Using WBadmin

First of all, make sure the additional disk you want to backup to is connected to the server/computer in question.  Now, open an elevated command-prompt (i.e. “run as administrator”) and type wbadmin get disks, you’ll get a list of disks in the following format:

Disk name: xxxxxxxxxxx
Disk number: x
Disk identifier: {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}

Look through the list for the disk you’d like to add as a backup destination and make a note of the “Disk identifier”.

Now, type wbadmin enable backup -addtarget:{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}.  You’ll receive a prompt asking you if you want to enable the backup with the above settings, type Y.

That’s it!

Special Considerations

Remember that Windows Backup will look for any and all your backup locations to run the backup.  This doesn’t mean they all have to be connected, but it does mean that at least ONE must be connected or the backup will fail.  So make sure that if you, like me, are using a hot-swap bay for a removable hard disks your system recognizes the drives being switched!

Doing this allows you to swap out different disks whenever you feel like it and Windows Backup will always have a spot to store your backups.  Cool, right?  Now, why it’s not easier/GUI driven… well maybe in future versions?
