    I have daily partition backup scheduled for my D data drive. My C system partition was low on disk space so I had to delete the D drive, extend C drive then create a new D drive and restore the contents. Only problem is the Windows Server 2008 backup utility cannot find the reference to the D drive anymore. What changes do I need to make so the D drive gets seamlessly backed up like it used to? -Kyle

    Modify the backup job, and re-select the d: drive would be the easiest method.

    That probably would be easiest. My concerns are 1) the current backups take up 650gb of a 1tb dedicated drive and 2) they are incremental backups. Ideally I'd like to keep the incremental backups going, plus I don't have enough disk space to do a second backup of the D drive so I'm assuming I'd have to clear out the disk and start a new backup..but that would leave me without a backup for the time it takes to establish the first one.

    Hi kcs2009,

    Check the output from "wbadmin enable backup"

    Check if you see a disk ID parameter, if yes, check with "wbadmin get disks", if a disk ID mismatch, then you then will need to change the diskid (http://networkadminkb.com/KB/a471/how-to-view-and-change-the-disk-id-in-windows-2008.aspx)

    Be aware I never did that, I strongly suggest to try in lab. Does that will work too is another story. (as the size change, does the incremental job will be able to fully restore it if the size of the target is shorter than the full partition when the first time backup was done in exemple)

    nb; A thread that show the disk ID parameter too (http://social.technet.microsoft.com/Forums/en/winserverfiles/thread/f9cd6cf1-7846-4364-b0eb-1ac5999ffe6f)

    If that tip does not work, you will have to change the backup job and re-run the full job in my own opinion.

    I took the risk and just reformatted the backup drive and rescheduled the incremental backups. The built in extend/shrink partition and backup functions in windows server could be a bit more robust in my opinion.
