  • Running Acronis Backup & Recovery on Windows Server 2012 Running Acronis Backup & Recovery on Windows Server 2012

    It becomes clear that Acronis didnt released build of Acronis Backup & Recovery, that will work on Windows Server 2012. Actually - support was not declared, but we can start Backup & Recovery on 2012... with a little trick.

    Sympthoms: after Backup & Recovery installation, management console didnt start with reference to "Acronis Managed Machine Service" (the service didnt start) (service name - MMS).

  • Step-by-step deploying AlwaysOn on MS SQL 2012 Step-by-step deploying AlwaysOn on MS SQL 2012

    Before Microsoft SQL Server 2012 and mechanism AlwaysOn were released, database administrators had only Database Mirroring as solution for replicating databases. It was the only option to get the "cheap" high availability. And Database Mirroring was not so good as it intended to be. Moreover, as my testings showed (and this is NOT written in documentation), it is NOT synchronous replication and transaction logs.

    In short - we have studied the behavior of the database during intensive recording and different faults. What failures we saw:

    • Planned shutdown of the master server (manual service stop) of the master server without any notification of the mirror server.
    • Unplanned shutdown of the master server.

    Oddly enough, it was a planned shutdown that showed that there is a difference between a mirrored database on the master and the mirror servers.

    Therefore, I would not recommend to use Database Mirroring in production deployments, but take a look at the AlwaysOn technology.
