Combine the power of Azure with your existing VMware or Hyper-V landscape in your regional datacenter.
The Azure Site Recovery Toolset contains disaster recovery solutions for different hypervisors, guest operating systems and databases running on-premises.

SAP supports its applications on Linux and Windows guests on VMware vSphere (SAP Note 1492000). You can use Azure Site Recovery with both guest operating systems starting with VMware vSphere 5 and higher. Additionally ASR covers many databases like Oracle, MS SQL Server, DB2 and Sybase.

For more information on prerequisites, costs, recommendations of this setup, check this blog. It contains many insights and implementation details how to set up such a scenario.

    Hello Claudia,

    We are currently looking to replicate a 2-Tier SAP Source system (including MSSQL) to an ASR recovery site.

    As I understand, this is unfortunately not recommended (it would be better to have a 3-Tier system), but this is historically setup like this at the customer.

    In your blogpost you state that ASR covers databases such as MSSQL, but I assume that this is in combination with classic DB replication methods (like it is stated in the other blog).

    Is there a recommendation how to move forward or what the best-practice would be in this case with a 2-Tier system?

    hi Lieven,

    you might find some interesting topics in section 6 of this blog. Furthermore, my Microsoft colleague who advises on this topic, listed some remarks:

    1. We do recommend using the native DBMS replication tool (alwayson, log shipping, dataguard, Hana Sys. Rep, DB2 HADR) for replicating the DB
    2. If ASR is used, it is difficult to do a DBMS point in time restore
    3. ASR on Windows (and some Linux distributions) can do a DB consistent replication (so ASR does communicate with the DB and ensures the filesystem is consistent)
    4. So technically you can use ASR to replicate a 2 tier system
    5. Based on customer deployments so far we really do not recommend it.
    6. Most 2 tier customers have moved their systems to 3 tier, but some have stayed 2 tier
    7. If a SAP system was very small (say 100-400GB) then I would think ASR would be an “ok” DR solution
    8. The preference is to move to 3 tier via SAP system copy procedure

    In case of further questions, you could get in touch directly with him.

    Best regards, Claudia
