Adding another disk to Windows Backup

Adding another disk to Windows Backup

Problem: Adding a disk to Windows Server Backup fails unless all disks in the rotation are attached. This is a known and unresolved problem for Server versions prior to 2012. It was in 2012 also, but there is a KB to resolve it (MS KB 2833738).

Workaround: Add the new disk via command-line to bypass this requirement.

Run the following commands from an elevated command prompt:

  1. Run “wbadmin get disks > C:\disks.txt”
  2. Open the c:\disks.txt. Copy the Disk Identifier for the relevant disk you are adding to the backup schedule. It will look like this… {xxxx}
  3. “wbadmin enable backup -addtarget:{xxxx}”
  4. “Y ” to “enable backup with above settings”
  5. “Y ” to “format the drive”
  6. Wait a minute. it will complete and return to command-prompt. You can exit command-prompt.
