DPM 2010 crashing when using sha256 certificate for tape backups RRS feed

  • Question

  • Hi,

    we are using DPM2010 to backup our exchange databases and do encrypted tape backups.  Recently we upgraded our certificate as it was expiring.  The new certificate is sha256 based.   Whenever DPM tries to run a backup with that certificate the DPM service crashes.

    are there any known issues with DPM and sha256 certificates?

  • Hi,

    DPM seems to only like 256 AES encryption.

    People who have to have deal with Real Certificate Authorities can use the following information to assist with their requests:
     
    If you are dealing with an organization that uses a Windows CA, have them issue a certificate based on the "Web Server" Template.
    If you are dealing with an organization that uses another vendors CA, request that they issue you a certificate with the following:
     
    Key Usages = Digital Signature, Non-Repudiation, Key Encipherment, Data Encipherment
    Extended Key Usage = Server Authentication
     
    The above match the values of your self generated certificate.
