Question on the DPM backup/recovery process RRS feed

  • Question

  • Hi,

    I am new to DPM and have a couple questions. We currently have a single DPM server backing up a few Hyper V servers, one back up is ran each night to disk, and then a weekly backup is ran each Sunday using Firestreamer to an external hard drive, which is rotated out each week. 

    Lets say we have a fire and lose everything, including our current DPM server, and we need to restore backups from the external hard drive. Would I be able to just set up a new DPM server from scratch and restore the backups, or would the backups somehow be "locked" to the old DPM server/database

    I guess that brings the next question, is it a good idea to backup the current DPM config, if so what is the best way to do this? I saw C:\Program Files\Microsoft System Center 2012 R2\DPM\DPM\bin\DdpmBackup.exe mentioned, is that what I should be using?

    In the event that this actually did happen, I just want to make sure I am prepared on the process of doing the recovery. The info I've seen on the subject online always mentions using a secondary DPM server which we do not have. Any help would be appreciated. 

    Thanks

  • Hi,

    So lets start with your first question regarding the virtual tape/external hard drive.
    The data that is stored on the virtual tapes can be imported to another DPM-server if you have not enabled encryption(How to Encrypt Data in a Protection Group).

    Your second question regarding the DPM-config. All configuration is stored in the DPM SQL-database so backing up this one to a remote location is strongly recommended.
    If your current DPM-server fails you will need to install a new DPM-server with the same version as your current one and restore the backed up database using the command-line tool DPMSync(Recover a backed up DPM server).

    As you probably understand but worth mentioning: The data stored in the DPM-diskpool will not be recovered but if the storage device, were you keep your daily backups, is still working you can attach it to the new/restored DPM-server.

    Note: What the DPMBackup.exe tool is doing is basically performing a backup of the DPM-database and the Reporting-database.

    Its a life/company-saver to have a well worked our Disaster Recovery-plan in place and if any information above is unclear, please do not hesitate to ask further questions!

    Kind Regards

  • When you install a new DPM server you can use "Recatalog imported tape" command to add backups created by another DPM server. See Recatalog an imported tape for more info.

    DpmBackup is an utility that creates a backup copy of DPM databases and all replica volumes, so it is not exactly what you're looking for if you need to protect local DPM server configuration data (files, registry)

    Reliable protection (and hassle-free recovery) of DPM server is best achieved using secondary server/DPM chaining. You can set up two DPM servers, distribute backup jobs between the two and, in addition, configure the servers to protect each other. Do not forget to take backup of DPM databases. See the following links for more info about DPM server protection:
