  • VMWare backup of a Domain controller

    Hello,

    I am wondering if I should use the "Windows Server Backup" feature in Windows 2008 to backup my domain controllers, or to backup the whole vmware machine in another disk.

    I am also wondering how this is done in actual enterprise, because mine is a lab learning environment.

    Do they backup machines just copying the vmware files in other locations every two hours or every day , or they use still the Windows Server feature within Windows 2008 ?

    Thanks in advance!

    Well here's what MS recommend for virtual DCs on Hyper-V:

      No. As per Scott's link it is not recommended.

      We use Backup Exec to backup our domain controllers. We also have multiple DC's and each has only a single task, being a DC, so if it fails we flatten metadata cleanup (only if it is unable to be properly demoted) and then rebuild.

      Being in a lab environment you shouldn't really be worried about backing up religiously. My lab consists of a prebuilt domain that i've hived off to OVF files. Single DC with DNS and DHCP and possibly a client. If i have issue is delete the old DC and re-import from the OVF file.

        Thanks a lot both for your help!.

        Scott28tt, really nice article , I have read it completely, amazing!.

        A question arises:

        If I take a snapshot of the virtualized domain controller (vmware in my case), when I used that snapshot, the issue would be that the USN would not propagate properly to the other DCs ?. I did not understand this.

          Microsoft have fixed the USN issue with Server 2012R2 DCs but they still recommend not snapshotting in a production environment

            Thanks a lot Ossian ! . That sounds like good news.

            I am also reading that you cannot take a snapshot as a backup for Exchange servers.

            THANKS!

              Snapshots are NOT backups! (repeat that several times to be sure!)

              I would not use snapshots on production machines, but use them a lot for deployment (to allow rollback if something fails)

                I agree.

                I use snapshots prior to making any big changes that affect only a single server and never ever across 2 or more servers.

                I never snap exchange or SQL either.

                  the ohters have said it already. snapshots are not backups.
                  you only make a snapshot for a short period of time, as a precaution or part of risk management.
                  if your operation fails, you roll back the snapshot.
                  Otherwise, commit the snapshot

                  too much shit occurs as a result of virtual guest have 5, 10, 15 snapshots.. filling up the drive and being unable to commit them.

                  Have seen same on both hyperV and esx
