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.

It worked for me too. – MadBoy Apr 1 '11 at 12:29

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.

For anyone curious, on Windows 2008 R2 this problem and the solution scales to at least five drives. However, I found that I was unable to set up more than two drives using Adding a Destination. That is, I needed to start from scratch with all five drives simultaneously connected for it to work. – Rhett Dec 3 '09 at 2:14
It's good to know command. Thanks – MadBoy Apr 1 '11 at 12:37
