Backup DPM Server 2016 itself RRS feed

  • Question

  • Hi,

    Currently, my company only invested on one DPM server.  A second DPM server still in discussion.  

    May I know is it sufficient to backup just the DPM SQL DB?  Can I just reinstall my DPM from scratch if it get corrupted and restore the SQL DB?  Will all recovery points get recovered as well?  

    Thank you.

  • Hello,

    Short answer: Yes.

    Long answer:

    Everything is stored in the DPM database, so this is the crucial component in DPM.

    There are three (3) ways of backing up your DPM servers with a secondary DPM server:

    1. Primary to secondary protection - The database and replicas stored on a primary DPM server can be backed up to a secondary DPM server. If the primary server fails the secondary server continues to back up protected workloads. If the primary server fails you can do either of the following: Rebuild the primary server and restore its database and replicas from the secondary server. Then move the protected workloads back to the primary server after the rebuild. Select to switch protection to the secondary DPM server. With this setting you then restore to the protected computer directly from the secondary server when the need arises. For instructions, see Set up secondary servers.

    2. DPM chaining - A chain of DPM servers provide protection, and each server protects the next one in in the chain. For example: DPM1 is protected by DPM2 (DPM1 is the primary and DPM2 is the secondary). DPM2 is protected by DPM3 (DPM2 is the primary and DPM3 is the secondary) For instructions, see Set up chaining.

    3. Cyclic protection - One DPM server is backed up by another DPM server, and vice versa. So that DPM1 protects DPM2, and likewise DPM2 protects DPM1. This is useful for small environments.

    The most common one is is option 1: "Primary to secondary protection".

    So if your primary DPM server would fail, you simply re-install the DPM server and then perform a restore the database from your secondary DPM server and finally move back the protected workloads to the newly installed DPM server.
