Windows Server Backup says the filename, directory name, or volume label is incorrect when adding another destination drive to the backup

  • 772

I have Windows Server 2008 R2 installed and running. I created a full server backup to an external portable drive (MyBook by WD). It scheduled and has been running with no errors for a week. I purchased another MyBook (same size too) to swap out so we have an offsite backup in rotation. I plugged the new drive in and ran through the wizard to add this drive as a destination. It gets to the end and says "The filename, directory name, or volume label is incorrect." Then says the backup has not been modified.

If I look in the disk managment, the external drive has been formatted and labeled exactly like the first drive, only with Disk_02 instead of Disk_01.

This is the second drive it has happened on. We had another drive that I assumed was just going bad so we bought this new one to replace it.

Edit: Also, this type of scenario was working just fine on a Windows Server 2008 machine. The boot drive went bad so I decided to start over with R2...

    I solved this by plugging both removable drives in while adding the second backup drive. I didn't need to do this in Server 2008, I guess R2 requires it or it's a bug.

  2. You can use Server Backup Command line.

    1. Use command line or UI to create backup schedule with a disk as backup target.
    2. Detach your first disk
    3. Use WBADMIN Command line for adding another disk to schedule.

    Sample Usage:

    WBADMIN ENABLE BACKUP -addtarget:{aa123d14-bba0-1dd9-0d93-80aaaa6bbb63}

    Note that the AddTarget parameter takes disk ID which can be got by running WBADMIN GET DISKS command.
