Cant add additional destinations to SBS Backup

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

1. Run the following command from an elevated command prompt to determine the Disk Identifier of the new disk:
        wbadmin get disks
   
2. 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.xx GB
   Used space : xxx.xx GB
3. Run the following command to add the new disk to the Scheduled backup.  Use the Disk Identifier from the previous step as the “AddTarget” parameter.
        WBADMIN ENABLE BACKUP -addtarget:{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}
   
4. When you receive the following prompt, type Y for Yes.

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