Server 2008 has a good backup solution however if a drive goes bad trying to add an new drive is a pain unless you use the command prompt!

Add a new disk to the backup schedule by running the wbadmin command from an elevated command prompt.

Run the following command from an elevated command prompt to determine the Disk Identifier of the new disk:
wbadmin get disks

Based on the output, locate the disk that will be added to the scheduled backup. Make a note of the Disk Identifier. The output will resemble the following:

Disk name: xxxxxxxxxxx
Disk number: x
Disk identifier: {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}
Total space:xxx.xxGB
Used space: xxx.xxGB

Run the following command to add the new disk to the Scheduled backup. Use t he Disk Identifier from the previous step as the AddTarget parameter.
WBADMIN ENABLE BACKUP -addtarget:{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}

When you receive the following prompt, type Y for Yes.

“Do you want to enable scheduled backups with the above settings?”
