Migration From 2008R2 to Azure RRS feed

  • Question

  • Hi All,

    I am migrating my DB to Azure. Now the requirement is :

    • I dont want to shut down R2.
    • I want to use this as similar to <Active-Passive mode> that is when Azure is down R2 should be up and when R2 is down Azure should be up.
    • For this I want a simple audit table which records the changes done in my R2 or azure what ever is up <in required tables>, For example if an update is run on the table I need to store the PK of updated row and "Update" in Operation column. If an insert is done then PK of that row and "Insert" in Operation and Simalar others.
    • This is similar to 'Always On - HA' feature of 2012 RC0. (I cant create a new instance of RC0)
    • The audit table will be used for knowing the operations done and replicating these in the instance which is currently in down mode, so that I always get recent updated records in the tables.
    • I am using a trigger methodology for this, but knowing the performances of Triggers, I dont want to use that.

    Please suggest alternative scenarios for solutions.

    If I am not clear in my requirement. Please ask.

    Thanks.

  • Hello,

    We can have a disaster recovery solution for  SQL Server databases in a hybrid-IT environment using AlwaysOn Availability Groups, database mirroring, log shipping, and backup and restore with Windows Azure blog storage.
    For example, in a AlwaysOn Availability Groups, some availability replicas running in Windows Azure VMs and other replicas running on-premise for cross-site disaster recovery.

  • Liu, My base DB is 2008 R2, So Always On AG is not an option for me.
